I have a great deal on a set of 8.5x20 et 31 and 9.5x20 et35. My concern is that the only tires I can find with close enough rolling diameters are 245/35/20s and 275/30/20s.
I've read through this twice and everything else I can find. I'm guessing this will be very close on my 2011 e92xi. Any help is appreciated.
