Why would BMW advice a tire set that has 0,96% difference in circumference when you can have a set (285) that only has 0,07% difference???!!!
Anyone running that size on an Xdrive? I've read some horror stories about demolished differentials on Xdrive with that setup...
Any advice?
I find that crazy as well. I run 245/285 on Xdrive with no problems.
