Hello guys,

I really need some help because i'm searching alot on the internet for fitment but i'm still not sure.
So i have a bmw 428i from end 2014 and bought z-performance zp2.1's in liquid metal. The size z-performance gave me were these:
front: 9x20 ET35
back: 10x20 ET35
I got bridgestone potenza s001 245 35 20 on the front and 275 30 20 on the back. Now the front fit perfect but in the back the wheel sticks out (check photos) and on hard bumps it hits the fender .. The rim just pokes a bit out of the fender, i think like 5-8mm or so.
Now my question to you guys is can i mount 245 35 20 in the back and have the tire fit without rubbing issues? I want to take the front tires to the back and buy some 235/35 20 for the front? Think it's going to be perfect that way. I am planning on lowering the car on air or coils btw.

Well... 245 on a 10" wide wheel will be stretch... I'm not a fan of that kind of setup. If your front fit fine, why changing it? In my opinion, you should simply put 265-30-20 in the rear and add a bit of camber to make it fit without scrapping tire after 1 year. staying in the below the -3 camber. I can fit a 20x10.5 + 41 in the rear with 275-30-20 on my 435 without rubbing.

hope it helps!

Will 265 work without rubbing? And i def don't want to mess around with camber!
Maybe 245 30 20 and 255 30 20?

I will order size 265 30 20 for the back tomorrow if anyone can assure me no rubbing issues and that the car can be lowered without issues

If you going to drop the car, you will have a bit camber (witch is normal, dont worry about it) You have to aligne the car, and should not have any rubbing issue on 265. But i'm not a pro, so maybe wait to have a few more answer about it.

Ok Thanks! I can imagine a 265 might work but will be very close if so. I think the tire will sit nice no question about it, also the sidewall on 265 30 20 is smaller. I like the aggressive look tho but the 275 is a tad too wide especially on top at the fender. Also Now it only rubs if i go too hard on bumps, I can drive the car pretty loose without rubbing but i want to make sure i will buy the right tire this time.

Tired of waiting, just ordered 265 30 20.
I did my calculations and my 10 ET35 wheel sticks out 0.065mm more then 10,5 ET42, wich is nothing IMO! And 265 on 10j will be thesame 'stretch' as 275 on 10,5, accually the 265 sidewall is a tiny bit smaller so that can only help me out more. I will post pics when the tire is on the car!

Nice!! show me some picture when you have it on the car!! Hope everything is going to fit well! Can't wait to put my wheel on my car too!

Tires are on, and the fitment is perfect imo, no camber added no rubbing whatsoever. Tire is nicely tucked Now i like it! Bridgestone doesn't make potenza s001 in the size i needed so my Tire guy adviced me a pair of yokohama advan sports in the back wich are also very good quality and match the s001 profilewise and ridewise.
Car will be lowered on coils or air in the future!
Ill upload a pic later today!

Here some pictures, the tyre has just the right amount of stretch on it! The wheel is exposed a little more now but i like that look. With full passengers the car doesn't rub even on hard bumps.
