widest tire that will fit on my setup
Guys, Help needed.
I got a set of 18 x 8.5" ET35 (square) rims fitted with 235/40/18 4s tires. I was told only 225/40/18 would fit but I went with 235 ones and they fit so I wonder where the line is. Would 245/40/18 fit? I have stock suspension. Is there a calculation that can tell me for sure? How can I tell the margin I have for my current setup? Do I turn my wheels and watch somewhere to see current margin? |

By measuring! I swear I spent half the winter on the ground in the garage with a bunch of rulers and squares, calculating and recalculating a super aggressive fitment on 17x9 with 255/40/17 tires. I'm cambered and rolled with a 1" drop so there was no tried and true fitment to copy.
Heres a website I found useful: http://www.42draftdesigns.com/wheel-offset-101/

Probably will fit on the fronts with some fender rolling. I have 245's on 8J ET40, with M4 arms which push the wheel out a good 12-15mm at the top. It's tight, but works.
The rear will cause rubbing I think. I have some room to fit lower ET, but probably not the extra 11.4mm an 8.5J ET35 will bring. |

Potenza PP S04's. No drop, no additional camber, only the extremely rare rub on a particular high speed compression dip. A little pokey, but I like the look. Took them off my old E90, and they fit! Maybe too much tire for most driving but mad grip at speed. I was wondering what I was going to replace the Potenza's with, they're almost done. Or do I get rid of them and go for the standard Apex 18" with 235's of some sort. (boring, but more mainstream look) I guess I know my answer.
