What would be the negative affects of putting a 255/35/18 tire on an 18x8 rims.

Also.....is it possible?

The other half of the question is I am running a 245/35/18 in the rear right now. What would the effects be if I decided to go with a 245/40/18 in rear....and I would plan to keep fronts at 225/40/18.

Thanks

Imagine the tire.... But thicker.
The problem with running a 255 on an 8 inch wheel I that your tire will sit wider than the rim. Problems with that is that it will be a bit more prone to rolling as the wall of the tire will be stretched over the outside. The rubber will have more travel if you will.

Rubbery handling.

ok......I think I'm gonna go with the Yokohama AVID ENVigor from Tirerack. Do 225/40/18 in front, and 245/40/18 in rear. We'll see what happens.

I knew the side wall was the concern here, but wanted to here waht you guys had to say.

Don't you have 8" all around? Why not put the same size tire up front?

Money, and then it wouldn't be staggered, and it won't fit.

I vote square. Even if that means 235's all around.

With a square setup, you'll see a handling improvement (less understeer). My old M3 had 17x7.5 with 225/45 and 17x8.5 with 245/40 and when I went to 8.5 with 245s all around, the handling was noticeably more neutral.

This. Square setup = win.

So...if I went 235's all around, then used spacers to tweak, that would kind of defeat the purpose...correct?

It's funny to see how people with cars that have staggered wheels want to go square, and people who's cars come square want to go staggered...

You can fit 245's up front.
If i can fit 255's all over the place, you can do it with 245.

I got a set of 19's last week. 245's on the front with a 35 offset, so you should be able to run the stock front with a 255 just fine.

I have ET 42 and am lowered significantly.....

I don't have a stock front

I don't have a stock wheel.

Curious... why would you want staggered?

But it looks better. That is all. I think I'm gonna go 235's all around though.

I would think with moar lowering, and more positive offset than me, you would have more tuck and be able to fit it. By my math, with 255's you should have 2mm less poke than I do, and I don't rub in front ever.

I have one index finger of clearance. I just checked. This is not only to edge fender well......but also near top of arc on tire...

I am running 235's up front and 255's in the rear. No rubbing in the rear. Of course, I also had my alignment shop do -1.0(i think it was one, maybe just under -1.0) camber on the rear wheels to pull them in a hair. So they sit and go up and down well within the rear arches. ie: No rubbing if you can pull camber on the rears with 255.

The offset on those BBS is prolly ET 38?

I agree that it looks better... on a 911. :)

Same here. Remember a 255 on an 8 won't have any more contact patch than a 235 on an 8, and will feel very sloppy.
