Tire Fitment - Rear 18x8.5, +20 offset Wheels

Wheels are 18x8.5. Front offset is +35, rear offset is +20, with 225/40ZR18 Lexani N3000 tires (As far as I can see, same as Nexen N3000) , on all corners.

Car is a 2006 E90 323i c/w OEM sports suspension.

Want to go to a staggered setup;

Front: 225/40ZR18
Rear: 255/35ZR18

Since the front size isn't changing figure fitment will not be an issue, but a bit concerned about rear fitment due to the wider tire.

Previously asked about fitment specifically for Hankook Ventus V12.

After some reading, debating going with Continental Extreme Contact DW, (appears to be a better tire then the Hankook V12 for about $130 more total).

Anyone have experience with the same wheel size, specifically with Continental Extreme Contact DW? Want to make sure no rubbing!!!

Bump...Anyone running a 255/35R18 (Continental Extreme Contact DW) on a 8.5 ET20 rim that can confirm fitment.

You shouldn't have any issues with that tire sizing.
