2010 2011 BMW 5 Series Forum F10 - View Single Post - What tire size do you drive on a staggered 20" setup?

I asked the dealer about the tires, he told me my warranty on suspension, drivetrain will void if I mount other tires than the star tires that BMW advises. The size on those is 275/30/20 and 245/35/20 and are runflat tires. 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?
