I used to ride with a guy who constantly got flats and complained about every brand/make of tire he ever had. He never missed an opportunity to ride in the road sweep on the shoulder that literally looked like a yard sale for glass, wire, wheel weights and everything else. As far as accelerated wear goes, lower pressures can cause more heat/wear. I'm not saying this is the case with the OP, but sometimes it isn't the tire, it's the pilot
