I have been reading up and it seems the consensus says that 275/40/17s will fit on the OEM wheels and will not rub. I just want to make doubly sure before I order a set.

Thanks!

I would love to know also. Anyone done this and care to comment?

Same as stock!!! Wow!!! I didnt know what came on my car :wall:





LOL I am teasing. Its funny how you can get carried away when posting on the internet

Hahaha and if you want to get REALLY technical, KDWS is the model, BFG is the brand

 

[Shocker]

mine will be on in a couple of weeks, i should get the goat today. Wavydavy is the only one I think who did the upgrade on size with the bfg's. But he replaced with Nitto slicks. so i doubt he has pics.

They may fit but it is not advised to put a 275/40/17 on an 8" wheel. You should have at least a 9" wheel and preferably a 9.5" wheel for that wide of a tire.

I had 275/40/20's on a 8.5 rim no problems. Whats the reason isnt something like the tire sits different? and "could" tilt the tire. If there is any problems when i put mine on I will let everyone know. I've been told by discount tires that a 285 would fit on stock rims.

The only issue is that the tire may "crown" some.

I had put 285 series rubber on my HD on a 16x6.5" wheel (vs. a normal 16x8 wheel) which they recommended I not do, the only reason being that it "crowned".

Well my opinion for what it is worth is don't bother.

No manufacturer that i could find (Yokohama, BFG, GY) rates a 275 tire as fitting on a 8in rim. You can do this on a 9in rim.

I know it looks like it will fit but i'm not inclined to go against the manufacturer recommendations.

The other issue is KDWS. Why go to a bigger tire but retain the compromise rubber. It may look great but some guy with 245/45-17 KD's will out brake, accelerate, and corner you.

BFGs website says 9"-11", the wheels on my car per the window sticker are 17x8.5. I work at a tire company so I can get them cheap. I will take the chance on the 1/2"

I was looking at my tires today they look so big compared to the 245's It looks like a tight fit. Anyone put the BFG's KDWS 275/40/17 on their car?

 

[FLORIT]

I'm running 275/35/18 on 18" x 9", 48mm offset wheels. They fit fine in THAT configuration.

I'm inclined to agree with PFYC and the manufacturer's recommendations. A 9" wheel for 275 tires... For those of you who have already bought the tires, nothing to lose by trying them out. For anyone considering the wider tire, also consider the wider wheel.

I do know from personal expierence that 275/40-17" tires will work on 17"x8.5" wheels. Many 94-96 Impala SS owners, including myself, have done this with no problems whatsoever. The smaller rim does pull a little bit of tread off the ground (crowning). Not bad or objectionable at all.

I thought our GTO rims were only 8" wide though?

 

[Shocker]

yea its 17x8 drivers are doing it and so far its working.

 

[Shag Finger]

My window sticker expressly says 17x8.5" wheels.

 

[Shocker]

is it a 18.5?

 

[FLORIT]

My window sticker expressly says 17x8.5" wheels.

Dude, save your window sticker. It will be worth something someday. It is misprinted.

The stock wheels on the 2004 Pontiac GTO are definitely 17" x 8".

Unless they made another mid-model-year change, like they did with the tstat housings...

 

[Shocker]

my window sticker say 17x8 5 spoke alloy wheels

Look Closer At Your Window Sticker

BFGs website says 9"-11", the wheels on my car per the window sticker are 17x8.5. I work at a tire company so I can get them cheap. I will take the chance on the 1/2"

I keep hearing folks say our wheels measure 8.5" and their info was gotten from the window sticker. WRONG, if you look it says 17' x 8'5 Spoke Alloy Wheels
It is typed with no spacing between the 8" spec for the wheel width and the 5 that's referring to the amount of spokes the wheel has. Soooooo, we have 17" x 8" Wheels! I just had to throw in my 2 bucks worth in! <--- Inflation is a killer
