I have a e46 325i sedan.

My current setup right now for wheels is 18x8.5 Et 32 wrapped with 245/40. But somehow the tire sidewall in the rear is rubbing on fenders.

What should i do?
1. Change tires to 225/40/R18?
2. Change wheels back to stock 16", if yes should i go with 205/55?

I really don't want to roll my fenders :(

TIA

245/40R18 and ET32? No wonder you're rubbing, the factory staggered setup has either 245/40R17 or 255/35R18 on ET50 wheels, so you have a full extra inch of tire diameter stuck out further than stock. Going to the correct diameter with either 225/40R18 or 255/35R18 tires should fix your issue.

Thank you! I forgot to mention that i am running a square setup. Thanks!

Why dont you want to roll your fenders? If you're running ET32 wheels, rolled fender is definitely required, unless your car is not lowered. Depending on how low the car is, changing the tires to 225/40/18 is unlikely to eliminate rubbing. My fenders are rolled, and I tried ET32 wheels with 255/35/18 tires, and I had rubbing all the time, even when accelerating on flat tarmac.

I wanted to preserve the car as much as I can. Glad to know changing tires wont make any difference. I guess I'll just go back to stock 16". Do you might happen to know which tires are best? 205/55 or 225/50?

Not to add confusion to the before mentioned posts. But I am currently on 17x9 +30 with a 245. Not slammed by any means but I had to trim my fenders back when I was on style 42's, so my 9 wides fit with no issue. That being said. 225 on a 8.5 would be a pretty mild stretch, but would probably get you plenty of clearance in the rear if you arent trying to dump the car.

18x8.5 +38 Front , 18x9 +42 in the rear. 225/40 and 255/35. (zoom on the front, should be able to see what 225 would look like with stretch in the front). Wish I had better pics of the 18's but I wasn't a fan of that setup so I didn't grab many.
Hope this helps, sorry for the massive photos. Message me if you have any more fitment questions. I've played with quite a few setups.

I see you're on stock suspension. I thought your car was lowered. 225/40/18 MAY clear, but I'm not 100% sure. You can always try playing with the camber setting, but I dont really like the idea of buying new rear tires every 5000 miles or so, and it may even be dangerous in the wet. Maybe try tires with rounder sidewalls like toyo or falken? I dont know about their new models, but I used toyo years ago, and it helped a lot.

Thanks, i'll see if i can get a used toyo tire to see if curved sidewalls will help. Appreciate your reply!
