My stock stumpy tires are 2.0 adrens. I'm pretty stoked on em but I was thinking about uping the size. How's the traction and ride for the 2.1 and 2.2 compared to the 2.0, is it worth dropping the dough for the up size and how's the rear tire clearance on the '06 stumpy fsr for the 2.2? Any help is appeiciated, thanks.

btw, the trails I ride are pretty smooth right now but they're really sandy for most of the year.
