Rears have a bit more room to go wider but would have to adjust the offset since +30 is showing a little poke, front fitment is tight on this one with +25.

Front fitment.
Waiting for Dinan to wrap up their R&D on the suspension goodies so I can drop it a hair to eliminate some of the gap. |
According to tyre and wheel calculator you have wheel outside diameter at front 679mm (26.7") and at rear 669mm (26.3") so rear wheel has 10 mm (1.5%) smaller outside diameter then front wheel. As I know it's not good for xDrive transfer case. As I see you have RWD car, you don't have this problem. How do you think is it necessary to use 235/40 + 265/35 tyres size on xDrive car with the same wheels? |
I believe as long as the rolling diameter is within 3% on an x drive car you're ok.
