What size tires for 8.5f46et and 9.0r50et? 18s

dread1 · 05-02-2010, 02:57 PM

Looking for tires kinda just want to know what size to runs.
I can only find topics related to people running the same widths but on 19s. This is with various and mixed opinions.

I want to run a 225/40/18 on a 18X8.5 front with a 46 offset and a 255/35/18 on a 18X9 rear with a 50 offset. I am on bmw sport suspension and do not want to dial in any camber or roll fenders.

Would I run into issues in doing this set up? At the very least run a 225/40/18f with a 245/35/18 out back or would I be fine with my intial set-up?

that should be safe... It looked like it would have been an easy fit with Yokohama s-drives when I tried to get the set of forgestars I ordered. Unfortunately three of them came new from the factory warped and got no support.

I think you could fit a 235 i the front too, but that MIGHT be a little risky. The rears should fit EASY (255's that is).

i've noticed that 225/255 seem to be the most common tire sizes people are running regardless of whether 18's or 19's.

225/255 are the largest to fit on stock rims, but they will also fit well on yours. I would go with this.

You must update this thread with pics!

I guess I should have changed the phrasing of the question a bit.

Will
F225/40/18 on 8.5 46offset rub? Yes/No
F235/40/18 on 8.5 46offset rub? Yes/No

R 245/35/18 on 9 50 offset rub? Yes/No
R 255/35/18 on 9 50 offset rub? Yes/No

I'm really againts rubing and rolling an dpulling fenders. This was the ofset recomended. So just want to make sure
