Alright so in the past few weeks I've burned through approximately 5 tubes and 2 tires. I blew two tubes last night (as a result of the tire) and am just completely frustrated. I will describe the problem with the tires further. What appears to happen is that I've gotten small holes and sort of a tear look where the lip of the rim meets the tire. Could I be doing this with something like skidding if I don't have my air pressure high enough (lumpy roads so it's a little low occaisionally). I can find any obvious burrs or anything on my rim but I was wondering if you guys knew of something telltale that I should look for.
also why can't this ever happen just a few blocks from where I live? Well thanks to whoever was the guy who gave me a lift back last night that's for sure.
