I'm running into all kinds of issues with my S4.

Here's my situation:

I am currently running Sumitomo 225/40/18's on Ronal 18x8's (18x8? not sure but I think that's it). The wheels poke out of the tires a little, something I'm not a fan of. I recently purchased Continental's -- 245/40/18's -- a size that apparently, many people with stock suspension S4's have used without any problems. I had them mounted and there was almost instant rubbing on the back of the tire. With the 225's on the 18s, there was maybe 3/4" there.

What's the best solution here? Spacers? How did you guys who ran this combination do it?

My other set of wheels are Ace Lola's -- 17x7.5 (again, I THINK, since this set is not in my possession right now).

Which option would you use?

A) Ronal 18x8's with 245/40/18's and spacers (if so, what size?)
B) Ronal with a narrower tire (what size?)
C) Ace Lola's 17x7.5's with 225/45/17s (stock?)
D) Ace Lola's with a wider size tire?

HELP!!

Do you mean the inside of the tire at control arms? or outside at the fenders?

kenji91

I meant... at the control arms, sorry for the confusion.

In the rear? If so, raise the car or run a spacer

kenji91

what size spacer should i use?

HIS4

235/40/18 is more common for cars with conservative drops or stock suspension. If you're going to do 245 a 35 series tire is required to make it fit. There's too much sidewall on a 245/40 to allow it to fit under the control arm.

kenji91

so which combination would you use if a 35 isnt an option?

HIS4

If so, 235/40 could still be pushing it depending on the brand of tire. There are some guys here who are running that size with minimal rubbing but 245/35 would be safer. Why is 35 series not an option?

kenji91

35's aren't an option because i live in new jersey, the pothole (and a**hole) capital of america.
