Anyhow, the center of my rear is wearing kind of quickly, too... as someone else said, just a couple of hundred miles and the text is rapidly disappearing. I wonder if that has to do with the road surface?
Anyhow, blah, blah, use the other parts of the tire, too... I challenge someone to commute in the Dallas area and use much of anything beyond the center two inches or so... without getting egregiously stupid/reckless. I may try the lower pressures that doxiedog recommended to see what that does for wear.
