Who has successfully put something larger than 245's on stock 18's

Just as the title says.

Would it cause any problems to put a 255 45 18, or even a 265 35 18 on stock 18" wheels?

My '04 wears 255s on 18s up front with a Pedders "no drop" kit, and no rubbing anywhere, no wheel well mods necessary.

I have 275/40/17 Pilot Sports on stock rears. I'm told that shouldn't work but it's never rubbed.

If you get drag bags, you could go 265 or 275 on 18s. I would still probably at least roll the rear fender lip or cut it off if youre going to have (adult) passengers in the back seat. I think 255 is max up front from what I have seen posted around here and talking to people.

He was talking about the STOCK 18s. I think that you could do 255, but not sure about 265.

I wouldn't put a 265 on the stock rim....255 would be pushing it for me

[Jim346]

The wheel is only 8" wide and has little sidewall. The 17s can get away with 275s because of the larger sidewall...but the 18s, I really doubt it.

And IIRC, the 255 would go on a 35 section (255/35/18) as the stock size is 235/40/18; and the best "fit" from a rolling-diameter POV would be a 265/35/18.
