I usually go through about a tire a month sometimes two, and the only tires that have lasted more than a month have been Botranger/Trek tires. I actually have a pair of trek tires on my bike right now and they've been on there for two months or actually almost three now! I went through conti-ultra gp's in a week and a half. I went through armadillos in a month and a half. I enjoy skidding I don't care about street cred' I just like getting sideways through turns.
