8's in front 9's in back?

[brazenorange06']

Is this the biggest setup I can go to without dealing with wheel well rubbing and having to roll panel's? This would be in an 18 inch format. has anyone had Good/bad experience with their Beyern's?

[BIGRED1]

you will have to roll the rear on a 9 inch

[s/c'd cav]

that depends on the offset of the wheel

the drift r's with a 52mm offset dont require the fenders to be rolled

[BOTLFED98]

Drift Rs 18x9 in the back forsure!

[Venom]

I have 18X9 with a perfect offset of +52. I use BFG 275/40/18. It rubbed extremely bad. Fenders pinned back maximum, sledge hammer work on the INNER wheel well, new shocks, rubber spring blocks, raised the rear 3/4", removed spare tire and accessories.

I think it rubs so bad because I got 275/40 when I should have got 275/35.

Good luck finding the Drift R's in the 18x9 format though. I've been searching all over....:bomb:

Yes the 40 series is why you had problems. The 35 series would have been a better (ideal) option

[brazenorange06']

so have none of you used beyern? what about bbs lm's?

There are people with the Beyern 5's in the rear but the offset is too far out therefore requires some rolling of the fender lip.

I believe the offset for those are 45mm and you need about 52mm to clear with a 275 tire.

[TampaGoat]

9 1/2's out back are easy too. theres even someone on here with a yellow goat i think with 10's out back.

ive never shopped for wheels and im slightly going off topic here but what is the offset? And is theyre an offset with 275s that does not require fender rolling whatsoever? also, what offset is going to take care of my strut rub issue? (sorry for the hijack i still think im slightly on topic)

Strut rub??? no high hijack:) thats what I made this thread for! I think out offset in 52. But i dont know for sure...Probably wrong...and no the increments the offsets are dealing with are so miniscule, that there's no way we could get a 275 under there without mods. besides, Why wouldnt you just get 265's? Are you on squeeze?,Turboed?, blown? i dont event have many traction issues with my 235's!!! just get good rubber!

stock offset is +48mm which means it is 48mm to the outside from the center of the wheel.

On the front, most go with a +40mm offset on an 8" width. This gives you 8 more mm away from the strut. (this is also a common aftermarket design spec for our bolt pattern, 5x120mm) :)

This spec also will work for the rear without issue if you keep the rim width the same 8" and use the stock sized tires.

keep in mind that if you increase the wheel diameter the tire (which is what rubs is higher up the strut, the strut leans inward as it goes up) This is why there more of a problem with 17" wheels and not the 18" or 19" that the car was designed for orignally.

For a 9" wheel to clear without rubbing on the lip you need something around a 50mm -55 mm. (not very common to find)


A very common rear wheel spec is 9.5" wide and 45mm offset, these work but require you to roll the fender or (use drag bags, heavy duty springs...which limit suspension travel)

The tire design also plays a role as some tires have a squared blocky shoulder and some have a rounded shoulder, the rounded ones give you more clearance to the fender lip. (Toyo and Nitto brand tires are 2 of the most used rounded ones, generally summer only stiff sidewalled tires)

BFG's are an example of the square shoulder tires.

Sir thank you very much! this is honestly the most informative reply anyone has ever given me! Where did you find that offset diagram? That was really helpful, but can I use an 18X8 in front with a 245 and a 18X9 using a 265 in back without rub? what would the proper offset be? regardless of rarity

[sporaclic]

why do you only have 235s? the stockers are 245 did you downgrade?

[s/c'd cav]

stock 18's are 235's , and most go up to 245's

stock 17's are 245's

[brazenorange06']

No, the factory 18's are equipped with 235's stock.(not to mention shitty bridgestone's) and the 17's are 245's(bfgoodrich) so i honestly just have them for the look

[sporaclic]

is that what makes the 18s not rub? or is it the tire profile that makes it rub?

The 1" larger diameter of the wheel tire sits farther up the strut (that tilts in as it goes up to the shock tower)

Plus sidewall bulge and shoulder... it's a combination of all.

It just gives you more slack in alignment then the 17" with 245 BFG's. The 17" with BFG's can be made to not rub but you have to be closer to the right alignment specs then the 18' combo.



Brazen , the picture was on discount tire directs website..., I just did a google images to find a diagram.

on a 9" (rear only) you need somewhere in the 50mm-55mm offset range to clear the fender lip, 55mm may contact on the inner with certain "wide running" tires. 45mm on a 9" wide will require mods (either rolling or suspension, some do both)



On an 8" you are safe out to 40mm (both front and rear) without problem, with the proper tire size for your rim.

[sporaclic]

so does the 18 inch w 245 fit better or worse than the 17 with 245?

should be slightly better, but it depends on your alignment.
