I'm curious as to what pressure you guys are running in your rear tire. My possibly flawed logic tells me that if you run it at 42, it's gonna have too rounded a profile and wear the center out quicker than normal. The reason I was thinking this is the case is because it's designed for a larger rim, and squeezing it on the stock one makes it rounded to begin with. My stock tire is beginning to wear thin, and I'm starting to toy with the idea of the 280 on mine. Just wanted to know what the ideal pressure for that tire is for the most even wear pattern. Also, if I get the tire, how hard is it gonna be to find a shop that will mount it for me seeing the stock rim is out of manufacturer spec?
