Haha ****ty Hutchinson Equinox's that cost like $9 each. However, I only ever got one pinch flat due to not keeping the psi up. I just recently started skidding a lot, just for fun because I knew I had a pair of gatorskins waiting to be mounted and couldn't justify changing tires when the ones I had were holding up alright. Anyways, within a few weeks of skidding I noticed about a quarter size of threads showing in one spot.
