Tire size

[Ackattack]

I've decided on what size of rear tire I wanna run: 315/35/20.

For the front I figure I'll have less issues running a smaller tire. I want something that has nearly the same sidewall height as the rear, so I figure a 275/40/18 fits that bill very well. I also know that this size is readily available (its what came on the rear of my vette). This size should also fit fairly well while driving down the road, as right now I have 275/50/17s that are about an inch taller.

Anyways, what do you all think of the tire size combo. Anyone have this size combo?
