Nitto 315\35\17 No fender roll. Spring boosters

[ericwilloughby]

Got these for $40 mounted and balanced so I just wanted to try them out. The traction is awesome. I have a first gear that I never knew I had.

You can see where they rub the lip. I think 275's would go up into the fender easily.

More pics. I tryed to roll the lip by cutting a slot every 3 inches and hitting it with a hammer and 2X4. Cracked the paint. I might try cutting the lip off with a jig saw. Edit: I did cut the lip, no rubbing issues. But the 275's may fit with no mods. It's close.

Yea...Fenders need rolled. You definitely need a wider wheel, that stock 8" isnt helping. But other than that Id like to know your progress.

[radkon]

Most folks don't have any problems with the 275's.

Kudo's for risking your tires and trying it out.

[ohsixbrazengto]

I may try to go with a 285 or a 305 now instead of a 275. just have to find a tire I like in that size.

With the 8" rim those tires probably aren't much wider than my BFG 275's on a 9.5" rim.

In the picture that is numbered 8, I can tell that those are wider than my 275's, but that sidewall looks like it is suffering. Probably would leave a really nice big footprint on some wider rims. Kudos for providing some new (at least to me) info.

[Lorider680]

FAce!

[GT086]

To be brutally honest I think it's stupid to put 315's on an 8" wide wheel BUT it looks amazing, so I can't fault you too much. These cars look so good with wide tires on the rear.

[TprGTO]

For some reason those tires do not look as wide as I thought they would from the pictures.

That's because it is squeezed onto an 8" wide wheel.

I had decided not to try the Nitto's. I was going to have PEP boys put on there 275's they had in stock just to see how they fit without having to buy them first. Luckily for me they had none at the time. I went back to the little tire shop that always comes through for me with customer service. The reason I got them mounted is it's a 1 man owned shop. No corporate office looking out for my safety and covering there ass.

I risked these tires because I got them for $40. I thought he meant each. Handed him $80 and he said no, $40 for the set. I gave him a $20 tip.

Anyway, want to see stupid. These stockers had 13,500 miles on them and went to 100 MPH every day. Wear bar at 8,000. Took a 1,300 mile road trip with 3" of cord showing at 10,500 miles.

Wheel width: They are to narrow. It's what the car came with, know what I mean. As far as that being the reason they almost fit. Yes and no. They fit, sort of, because of the roll over. If the wheel were wider with the same backspacing they would hang over worse. But anyone buying new, wider, wheels should be getting there extra wheel width spaced to the inside of the wheel well. So wider wheels "should" properly spaced, move all that extra roll over to the inside and they "should" fit better. Not worse.

I've decided I love the overhang. A little less on the rear would be better but I wish there were some on the front.

And here is the spring booster. I didn't know they still made these. $10 for the set at Autozone. I know this is cheap ass. It's just research. I have $70 in this. tires, $40, tip $20, $10 spring boosters.

The Nitto Drag Radials have a very rounded shoulder.
The BFG Drag Radials have a very square shoulder.

That is why it is easier to fit the 275 Nitto's than the BFG's.

The traction from a dig is amazing. No more drifting for me. It is now impossible. This cured me of the desire to take the curves. I was 16 and stupid crazy. 110 MPH into a guard rail. Sheared the carb off and started a fire. Ripped the Craiger off the wheel studs. Flipped the car over and smashed the top onto the 3 of us. Guy behind me hit the seat so hard it pulled all the bolts out of the floor. The A pillar is wrapped around the steering wheel. When it was over I was laying in the center console looking into the rear seats. The only way out was temporarily blocked by my unconscious friend in the pas seat. & the guy in back could see smoke.

No more fast curves for me.

No crap, these 315's almost fit with no fender roll. If the extra wheel width is all backspaced, to the center line of the car, they would be in there no problem. I doubt you'd even need bags. I really can't see a problem with anything narrow than these 315's.

Rolling is not working for me. I will be cutting with a jig saw this weekend and there is a chance these things will go up into the fender well.

Do yourself a favor, and use a 4" angle grinder. The jigsaw could get messy if you are not careful, and the grinder makes very quick work of it.

Use an angle grinder and make long smooth sweeps. Should take you about 15-20 minutes to remove half of the lip (down to the spot welds).

Then take and put some tape on the lip and see if it rubs, if it does, look at the tape to see where you need to grind some more.

The finish it off with some coarse wet dry sand paper to remove the roughness and sharp edges.

[ericwilloughby]

I can't see them not fitting. As long as you get the extra wheel width all on the inside and they are Nitto's.

[Pro GTO]

But at some point adding wheel width towards the centerline is going to run into interference with the suspension, right?
Pardon me for resurrecting this thread but I've learned a lot from it ... Has anyone ever computed the "magic" offset and backspacing numbers to get the most wheel and tire width under the car?

[ericwilloughby]

There is a lot of space on the inside of the wheel. The issue is with the lip. I cut mine off with a jig saw a couple weeks ago and now I have no rub at all with the Nitto 315's. They actually go up inside the fender.

The first photo is the clearance between the tire and shock >1".
The second is the cleanance between the tire and frame where the spring seats 1". Notice the spring boosters. They are set to give me 2 fingerwidth between the tire and going inside the fender. 3rd pic.

Yeah, but they are also pulled in onto an 8" wheel. I wonder if they would fit so well on a proper sized wheel?

[ericwilloughby]

They would fit better. More of the tire would be on the inside and not interfere with the lip. But I couldn't see going over a 10 inch wheel. If you push it inside more than that the wheel will be getting close to the shock.

I had 275's on stock wheels, and I now have 275's on 9.5" wheels. If you lay them flat on the ground next to each other, the one on the 9.5" wheel is considerably wider. Like more than an inch wider. The narrower wheel compresses the tire. I am not saying it cannot be done, but it will be a tight squeeze if it does fit.

Your right, a wider wheel would make the tire wider. You say going 1.5 wider on the wheel made the same 275 tire 1 " wider? Good info. I didn't know mine were pulled in that much. I should have measured them off the wheel so I would know how much. I didn't think about it. I will when I buy the next set.

I'm starting to confuse myself:)

The tire would be wider on a bigger wheel. But how much?

What would happen if: I went to a 10" wheel with the same front set. The tire would be moved inside 2" and hang over the rim less. So even though the tire would be wider it would hang over the wheel less. Is this correct? It could never hang over the wheel more than it does on a narrower rim. So if it fits now it would have to fit, hang over less, on a wider rim.

This last one shows how, where, any tire will hit the spot where it comes out of the fender. It is the same as the stock tire. Why this isn't a problem I don't know. But it's not.

[jcain]

how much air do you have in these things? with my 275s on stock 17s, cut/rolled at 12psi they would barely clear

[BobthePhotoGuy]

Look at the cross section of the tire.

Take two straight edges and lay them across the tire (like you did in that earlier pic) on both the inside and the outside. Now compare that to wha the manufacturer lists for the cross section. For a 10.5" rim, the width is listed as 12.13.

The only reason why they fit is cuz it's on a 8" rim which is pulling the tire in and it's not as wide as it should be. To say a 315 would fit on our cars without any aftermarket wider fenders is just dumb. What you are doing is just dangrous IMO. I would not drive that car with those tires.

So if it fits now it would have to fit, hang over less, on a wider rim.
It was definetly at least an inch wider. I did not measure the difference exactly. The thing is, in order to fit a 10" wheel, some of the wheel will be further out, as well as in. Unless you can find a 10" wheel with some crazy offset, like 90mm. I have 275's on 9.5" wheels with a 45mm offset, and they barely fit. My fenders are cut about as much as yours, but I have stock rear suspension. There is a little room to go inboard, but it doesn't appear to be enough for the difference between a 275 and a 315.

[BobthePhotoGuy]

Eric, just want to point out a few things.

315/35R17 Nittos have a recommended wheel width of 10.5". By installing them on an 8" rim, you are not only going to cause excessive wear to the center of the tire, you are also stressing the tire beyond it's structural design. It may seem fine, but if you end up in a situation that requires extremely aggressive maneuvers, things could get ugly.

I have 18x9.5 rims at 45mm offset, running 275/35R18 BFG Drag Radials. These tires have a sectional width of 10.9" on a 9.5" rim.

Clearance on my setup was quite close. I had less than 1 inch of clearance on the inside and basically no clearance on the outside (I would still get a little bit of rubbing when going in a driveway at an angle). My fenders were ground down to about where yours are.

Here are a couple of pics of the inside clearance:
http://www.bobthephotoguy.com/misc/Tire2.jpg
http://www.bobthephotoguy.com/misc/Tire1.jpg

This shot shows where the outside of the tire was in reference to the fender.
http://www.bobthephotoguy.com/GTO2/crw_8431_std.jp g

Now look at the difference between my 275/35R18 and the 315/35R17 widths, it's 1.23" (12.13 - 10.9 = 1.23). That means you have to have room for a little more than 1/2" on the inside AND the outside. If you do get a custom backspaced 10.5" rim so there is about 1/4" clearance on the inside, you still have 1/2" more tire going to the outside.

Sorry, it just won't work without some serious fender modification.

I give you credit for doing it! If ti works for you, roll with it. But I do have to agree BobThePhotoGuy in the sense that if you have to drive aggressively left and right, it COULD be dangerous. AS long as you accept the risk, go for it, as you said it your car!

[ericwilloughby]

Black marshmallows, hahaha. What is the offset of the factory 17's?

The offset is the distance from the hub to the outside of the wheel. So you would want to stay at 30-45mm. Not 90mm, right?

I just looked at the new Nitto's. I stole these things for $40:) They are $175 new. I didn't know that they don't make them in any size between 275 and 315. That sucks. I would chose the BFG 275 if I were buying new.

I like your wheels Bob. Send me a link to more pictures. I doubt the Nitto is that much wider than the BFG but it doesn't matter. On a wider wheel, same offset, there would be less tire hanging over the rim. It would fit easily because it fits now, hanging over the rim about 1 inch. The problem would be do they make a wheel with the same offset? I don't know what the factory offset is. But I have about an inch between the wheel and fender lip so there is a little room for a wheel with more offset.

Long technically boring post below!!

Offset is how much the hub mount is offset from the wheel center.

You don't really want to use the same offset on an 8" wheel and a 9.5" wheel.

Backspacing is the distance from the hub mount to the inside lip.

The stock wheels have a 48mm offset. So take the rim width and change it to millimeters. 8" = 203.2mm.
Now divide that in half. 203.2/2 = 101.6mm. This is the wheel centerline.
Now add the offset to that. 101.6 + 48 = 149.6mm.
That is your backspace (the distance from the hub mount to the inside wheel lip).

Now if you take 101.6 and subtract the offset, you get the frontspace. 101.6-48 = 53.6mm. That is the distance from the hub mount to the outside lip.

Now if you change the rim to 9.5" wide.
9.5" = 241.3mm
241.3/2 = 120.65mm is the wheel centerline.

Now take the wheel center and using the stock 48mm offset, calculate the frontspacing and backspacing.
120.65+48 = 168.65mm backspacing
120.65-48 = 72.65mm frontspacing

Now compare the 8" wheel to 9.5" backspacing
8" = 149.6mm
9.5" = 168.65mm

So the 9.5" wheel is going to have 19.05mm backspacing or 3/4" (19.05mm = .75") more backspacing.

Now the front spacing
8" = 53.6mm
9.5" = 72.65mm
Frontspacing is 19.05mm or 3/4"
So you basically added 3/4" to the front and 3/4" to the back of the rim.
Now if you did a 10" rim @ 48mm offset, it would add 1" to the front and the back. This would start to get too close to the suspension.

What you need to do is figure out what a good backspacing would be and use that to calculate the offset.

Let's use my 9.5" wheel with a 45mm offset as a starting point. I have about 1" of clearance between the tire and the suspension. Since the tire will flex back and forth and the tire crosssection can vary with brand, we'll keep about 1/2" clearance.
First, calculate the backspacing:
9.5" = 241.3mm
241.3/2 = 120.65mm
120.65+45 = 165.65mm of backspacing

Now if we figure on going with a 1/2" more backspacing:
1/2" = 12.7mm
So
165.65+12.7 = 178.35mm of backspacing as the optimal

So what would be the optimal offset for a 10" wide wheel?

First caclulate the wheel center.

10" = 254mm
254/2 = 127mm center line

Now take the wheel centerline and subtract it from our optimal backspace:
178.35-127 = 51.35mm offset

So a 10" wheel with a 51mm offset could be considered optimal.

Now this doesn't take into account the front side. You need to watch that measurement so you don't get too far out and end up with the tire hitting the fender. With this 10" @ 51mm offset, the front spacing would be 76mm, using my 9.5" @ 45mm, you have a difference of .35mm (76mm - 75.65). Very minimal difference.

So if you get a 10" wide wheel with a 51mm offset, it SHOULD fit in the fender well with a 275 wide tire. For what it is worth, a 315 tire on this rim will be about 1.5" wider than a 275. I highly doubt that a 315 will fit without some heavy modifications.

Now compare the 8" wheel to 9.5" backspacing
8" = 149.6mm
9.5" = 168.65mm

So the 9.5" wheel is going to have 19.05mm backspacing or 3/4" (19.05mm = .75") more backspacing.

Now the front spacing
8" = 53.6mm

So a 10" wheel with a 51mm offset could be considered optimal.

The tire overhang is a result of using rims that are too narrow. Of course wider rims will reduce the tire overhang, but it will also cause the tire to widen. Arim that is too narrow can also cause the center of the tread to bow outward and pull the shoulder down towards the rim.

Here are a couple of pictures of my 04 (traded for an 06 and haven't yet installed all the funstuff except the stereo).

Wow, all these years I thought the offset was the distance from the HUB to the outside edge of the wheel.

I agree, except that I think it would fit with a 45mm offset.:)

After reading all that and knowing I have 9.5" wheels and knowing I still had some rubbing you still think that a tire that is 1.5" wider would fit on 9.5" with 45mm offset?

I'm speaking from experience, I have the rims with the BFG DR sitting in my garage right now, I can take measurements of the tire width really easily. I can tell you that a 315 on 9.5" a rim with a 45mm offset WILL NOT fit. Period!! (unless you want to cut the fenders and add flares, or jack the backend up so high the tire doesn't get close to the fender).

Here is another pic, pay particular attention to the relationship of the outside edge of the tire and the fender. Now how would 3/4" of more tire on the outside fit into the wheel well?

Don't worry, you're safe. You'll never get the opportunity to drive this car. It's too much for you.

Dumb. Bite me. The 315's did fit. There's the damn picture dumb ***.

You don't have to like it but don't call me names....
Your car is too much for me? You my friend are one of the dumbest people I have come across on this forum.

You do understand that you are losing over an inch of width since you mounted those on an 8" rim? On a 10.5" rim those tires would not work on our cars. We do have people running 305's on the correct size rim and they had to do suspension work to get them to fit (aka stiffer springs and lifting the rear 1.5-2", etc).

Now I'm running 275/35/18 BFG DR's on my car on 9.5" rims with quite a bit of suspension work and my tires still rub. Also yes I did grind the fenders down to the spot welds. So for you to sit there and say that 315's will fit on our cars is just stupid, you really don't seem to know what you are talking about.

[ericwilloughby]

You are a real dip shit. Just because you didn't or can't doesn't mean it's not possible.

1. They may not work on a 10.5" rim. We never spoke of that. They are on an 8" rim. They won't work on ANY rim with more frontspace.

2. Nitto 555r's do not come in 305 or 295 in 17's today. I qualified my statements very well. I said NITTO's. We are taking about Nitto's hard head.

For you to argue that they will not fit is stupid. I have the damn tires, pictures, and proof. Now they won't fit with the wrong frontspacing. But they do fit "as I have them". You don't like how I have them and that is fine. I don't care. They are on there. They fit. And I cut well past the spot weld. You assume to much. Qualify your statements and compare apples to apples or shut up.

I'm not certain of the term offset anymore. I have to relearn that. You are speaking from experience with BFG's that are wider than Nitto's of the same tire size. I'm sure bigger BFG's wouldn't work.

I'm not sure they would fit on a 45mm offset. Cause I don't know what that is. But Since I have them on there now. If I had a wider wheel with the same frontspacing I know for a fact that Nitto 315 would fit. With my cut fender lip of course. Cause they fit now.

I love that color:) and the chrome badges.

Hey Bob. I think there may be some misspoken explanations in your write up. You said the spacing is measured from the center line of the wheel but then you say you take that measurement and add or subtract it from the hub mount point. Sounds like you are assuming those 2 things, the centerline and hub mount point are in the same location.

Can you verify this for me. I don't want to learn it wrong again.

The backspacing is calculated from the centerline. That is the starting point.

wheel centerline + offset = backspacing (for our cars, some cars have a negative backspacing, in that case you would subtract the offset from the centerline.

Pictures might help you to visualize.

First off as I said they are over an inch less wide than they should be. So instead of being the size of a 315/35/17 (12.13") they are really only 10.9-11", the size of a 275/40/18-275/40/17 which is why they fit. Do you now understand what I am saying. YES you may have a 315 on there but cuz of the width of the rim you got them on they are only as wide as a 275. I hope your tire blows out :D

[ericwilloughby]

Wow. Learned something new again. Offset is the distance from the centerline of the wheel to the hub mounting point. It has nothing to do with frontspace or backspace except that you can use it to calculate what they may be. Copy on that.

So, I was speaking in error when I said if the offset stayed the same on wider wheels they would fit. What I should have said and later did say is if the frontspace stayed the same they, Nitto 315's, would fit.

So on wider wheels you would need more offset, like 24v said earlier. He said like 90mm, was joking but he was correct in going with more offset.

[BobthePhotoGuy]

I'm not certain of the term offset anymore. I have to relearn that. You are speaking from experience with BFG's that are wider than Nitto's of the same tire size. I'm sure bigger BFG's wouldn't work.

I'm not sure they would fit on a 45mm offset. Cause I don't know what that is. But Since I have them on there now. If I had a wider wheel with the same frontspacing I know for a fact that Nitto 315 would fit. With my cut fender lip of course. Cause they fit now.

I love that color:) and the chrome badges.

BFG's fit wider than Nitto's because they have a square shoulder, while the Nitto's have a more rounded shoulder (shoulder is where the tread meets the sidewall). The reason the Nittos fit smaller is because the round shoulder allows the tire to go farther into the wheel well before it rubs. This statement holds true if they are BOTH the same size tire.

With the 315's mounted on an 8" rim, I bet that your maximum width is less than 11". Put a straight edge on the front and back and measure the distance between the straight edges. The maximum width on the recomended tires size is 12.13". So in essence you are pulling the sides of the tire inward and making it more narrow. This in turn puts tremendous stress on the beads, distorts the sidewall from it's intended use and causes the tread to push up in the middle, making the tire vary unsafe.

Remember that even if you keep the same frontspacing, you also have to keep the backspacing inline. You can only go in so far before hitting the suspension. The scenario with the 10" wheel above is about the max you will be able to do (you could probably get away with a 55mm offset without any problems, though that only moves the wheel in by 1/8").

That is a pic from a year or two ago. I believe it is Brent and he was running 10's at the time.

Someone else might be able to chime in with more info. I kept the pic just because it shows how much the GTO can squat when launching with the stock suspension.

[ericwilloughby]

Ok, I have literally spent the last 2 hours on this. I took the wheel off and did a lot, and I mean 2 hours of measuring. I even cut some AL strips to lay against the rim. The tire is only 11" wide. How wide it would be on a wider wheel??? 12" Doesn't matter. It is now hanging over the rim 1 1\4". That's a lot. And it is not rubbing the cut lip but darn close. On any wider wheel there would be LESS overhang of the rim. More overall width but less overhang. As long as the front spacing is the same or less it would fit. It meaning Nitto 315.

Also. These are 8.8 inch wheels. 224 mm. Outside.
159mm backspacing.
65mm frontspacing.

Doing the math that's 47 mm offset. I believe 45 is what I've read you guys saying. Ok.

I agree these tires are pulled in bad. They wouldn't fit on a stock rim otherwise. If and when I buy wheels, I'll get 10 or 10.5 and keep the same front spacing. So the offset would be 80-96. Shit. 24v wasn't joking. He really did mean 90mm:drink:

Me too. I've been looking at these TSW's. But at 17x7 or 18x9 and 42 mm offset, these just aren't even close to cutting it. None of those figures are what I'm looking for. I doubt I would find something that fits no mater what it looks like. I need a 17x9.5 or 10 and 70-80mm offset.

[wolfdogs]

well.. dont want to take the wind out of your sails, but they might look wider on the rims..cause the body is wider, but with the mushroomed tread surface from having them on the incorrect rim width is giving you the same contact patch as the stock tire, maybe a tiny tiny bit bigger, but not enough to make it worth the risk of debeading on a hard cornering manuever. Every component of the tires construction is designed to function under the proper inflation and rim width for a specific load on a particular vehicle. The crown edge wedges incorroparated into the belt package are not happy campers on those narrow rims, an neither is the cord body thats trying to stabilize the footprint thru the belt package thats going to weakend and begin to squirm after some cornering, causing irregular tread block wear... maybe even river-wear.. which is a wavy wear pattern caused by belts shifting.

in an emergency manuever, such as a spin out due to a sudden lane change or loss of control causing the car to go sideways, the crown edge can roll under and pop the bead off the rim......... would sure hate to read something bad down the line on this forum....

not a good idea what you did here, broh. not good. just my 2 cents and 20 years as a tire/testing engineer for the U.S. Govt.

Yeah, you are not going to find an off the shelf rim with that high of an offset. I think the highest I have seen are the roh drift r's. I believe they are 50 something on a 9" wheel. Your best bet is to either resign to a regular sized tire on an off the shelf wheel, or call someone like CCW, and see what they can make for you.

Warning!!
Long technically boring post below!!

Offset is how much the hub mount is offset from the wheel center.

You don't really want to use the same offset on an 8" wheel and a 9.5" wheel.

Backspacing is the distance from the hub mount to the inside lip.

The stock wheels have a 48mm offset. So take the rim width and change it to millimeters. 8" = 203.2mm.
Now divide that in half. 203.2/2 = 101.6mm. This is the wheel centerline.
Now add the offset to that. 101.6 + 48 = 149.6mm.
That is your backspace (the distance from the hub mount to the inside wheel lip).

Now if you take 101.6 and subtract the offset, you get the frontspace. 101.6-48 = 53.6mm. That is the distance from the hub mount to the outside lip.

Now if you change the rim to 9.5" wide.
9.5" = 241.3mm
241.3/2 = 120.65mm is the wheel centerline.

Now take the wheel center and using the stock 48mm offset, calculate the frontspacing and backspacing.
120.65+48 = 168.65mm backspacing
120.65-48 = 72.65mm frontspacing

Now compare the 8" wheel to 9.5" backspacing
8" = 149.6mm
9.5" = 168.65mm

So the 9.5" wheel is going to have 19.05mm backspacing or 3/4" (19.05mm = .75") more backspacing.

Now the front spacing
8" = 53.6mm
9.5" = 72.65mm
Frontspacing is 19.05mm or 3/4"
So you basically added 3/4" to the front and 3/4" to the back of the rim.
Now if you did a 10" rim @ 48mm offset, it would add 1" to the front and the back. This would start to get too close to the suspension.

What you need to do is figure out what a good backspacing would be and use that to calculate the offset.

Let's use my 9.5" wheel with a 45mm offset as a starting point. I have about 1" of clearance between the tire and the suspension. Since the tire will flex back and forth and the tire crosssection can vary with brand, we'll keep about 1/2" clearance.
First, calculate the backspacing:
9.5" = 241.3mm
241.3/2 = 120.65mm
120.65+45 = 165.65mm of backspacing

Now if we figure on going with a 1/2" more backspacing:
1/2" = 12.7mm
So
165.65+12.7 = 178.35mm of backspacing as the optimal

So what would be the optimal offset for a 10" wide wheel?

First caclulate the wheel center.

10" = 254mm
254/2 = 127mm center line

Now take the wheel centerline and subtract it from our optimal backspace:
178.35-127 = 51.35mm offset

So a 10" wheel with a 51mm offset could be considered optimal.

Now this doesn't take into account the front side. You need to watch that measurement so you don't get too far out and end up with the tire hitting the fender. With this 10" @ 51mm offset, the front spacing would be 76mm, using my 9.5" @ 45mm, you have a difference of .35mm (76mm - 75.65). Very minimal difference.

So if you get a 10" wide wheel with a 51mm offset, it SHOULD fit in the fender well with a 275 wide tire. For what it is worth, a 315 tire on this rim will be about 1.5" wider than a 275. I highly doubt that a 315 will fit without some heavy modifications.


:iagree: WOW great info anyone else have to read this like 4 or 5 times??

There was a pic a couple of years ago doing a WS6 wheel with 315's on them. He didn't drive the car as far as I can remember but they weren't rubbing sitting there.

275's on the WS6(17x9) wheels fit with no problems. I have pictures of them that I posted a couple of years ago. There is another member here running WS6 wheels all the way around but had the fronts cut 1" shorter.

The offsets are pretty much the same as my ROH wheels, 52mm I believe. My 275's don't rub at all. My 275 Nittos never rubbed on the stock wheels either.

I also ran BFG 315 DR's on my WS6 wheels about 10 years ago with no problems. My parent's both ran 315 BFG Comp TA's on both of their Comp TA's with no problems.

well.. dont want to take the wind out of your sails, but they might look wider on the rims..cause the body is wider, but with the mushroomed tread surface from having them on the incorrect rim width is giving you the same contact patch as the stock tire, maybe a tiny tiny bit bigger, but not enough to make it worth the risk of debeading on a hard cornering manuever. Every component of the tires construction is designed to function under the proper inflation and rim width for a specific load on a particular vehicle. The crown edge wedges incorroparated into the belt package are not happy campers on those narrow rims, an neither is the cord body thats trying to stabilize the footprint thru the belt package thats going to weakend and begin to squirm after some cornering, causing irregular tread block wear... maybe even river-wear.. which is a wavy wear pattern caused by belts shifting.

in an emergency manuever, such as a spin out due to a sudden lane change or loss of control causing the car to go sideways, the crown edge can roll under and pop the bead off the rim......... would sure hate to read something bad down the line on this forum....

not a good idea what you did here, broh. not good. just my 2 cents and 20 years as a tire/testing engineer for the U.S. Govt.

I'm sailing just fine:) They may not be much wider than stock but they hold all I can give them in 1st gear where as before 1st and the shift into 2nd was just a smoke cloud.

These $40 tires took me from 13.5 to 12.8

I will be buying the BFG 275's next time. Unless I find another set of $40 tires.

food for thought:

Straight from the Industry's horses mouth. the Tire and Rim Assoc. of America, who allows the tire companies to include it in their tech data.

RIM WIDTH
Correct rim width ensures flex at the designed flex point in a tire sidewall for optimum tire performance.

If the rim is too narrow, the flex point moves toward the shoulder area, creating heat buildup in the shoulder, which reduces tire life and could result in failure.

If the rim is too wide, the flex point moves towards the rim area, causing heat buildup in the lower sidewall, which reduces tire life and could result in failure.

Within the acceptable range of rim widths, one can select wider or narrower rims than the measuring rim. Selection of a wider rim, from within the approved range, (T & RA tables) stiffens the sidewall and improves handling at the expense of handling. If carried too extreme, either too narrow or too wide of a rim, it can result in uneven tread/pavement contact pressure causing uneven wear and potentially reduced traction, or increased vulnerability to bead dis-lodgement. Always check with your Dunlop dealer for permissible rim width options.

Remember - safe clearance must be determined for a particular tire/rim contender and vehicle.

Wider rims may offer some performance advantages over narrow rims. A wider rim increases the distance between the beads, which results in a straighter sidewall, which stiffens it. This results in quicker steering response and higher cornering forces.


Negatively, the straightened sidewall transmits more road shock to the wheel and suspension, placing greater stress on chassis and suspension parts and delivering a harsher ride. The straighter sidewall exposes the rim, making the wheel more susceptible to damage.

A narrower rim pulls the beads closer together, curving the sidewalls. This increased curvature allows the sidewall to flex more readily over bumps and absorb more road shock during driving. This offers a softer ride.

Eric...you must be floatin on marshmallows!!!

[ericwilloughby]

Yeah, haha, I have cheap wrinkle walls:)

I don't burn through the corners that's for sure. I can feel the instability. I'm used to drifting the BFG stockers though. I can handle it. Not that I want to go back to that.

If it gets away from me I'll just get the chain and have someone pull me out. Like I did last time :secret: :gears:

outta the snow???:iagree:

[ericwilloughby]

No snow, I was drifting with people in the back seat and it caught traction and around she went and off the road completely backwards. All 4 tires in the grass. I got lucky. Stopped with a fence at 1 quarter and the speed limit sign on the other. No more drifting with these sticky meats.

I cut the pass lip weeks ago but just got around to cutting the drivers lip today. Without the lip I am able to put the rear end back down to a ride height of just a few inches above the tire.
