235/40/18 & 265/35/18 on 335xi Coupe ?

I'd like to change the tire size (not wheel size) on my 2008 335xi Coupe w/Sports Package to 235/40/18 (front) and 265/35/18 (Rear). Has anyone experienced any problems with such a change? Thanks.

235/40R18 is no problem up front, but the rear wheel is only 8.5" wide which limits you to 255/35R18.

It's not recommended to use 265 tires on 8.5 rims.

I just changed my Pirellis for Yok's and the Pirellis have only 3K miles on them. Im trying to sell them for $500.00 for all. They are the Pirelli P Nero Zero all season Runflats. 235/40/18 fronts and 255/35/18 rears. Perfect fit for your ride.

That size is stretched to the point where you're doing more harm than good versus 255/35R18. It is outside the recommended rim width range by the vast majority of tire manufacturers.
