I bought these from a fellow TMO member who's on a race team. They were only used for 1 race so still have a lot of life in them. Reason for selling is because I chickened out of finally moving up to slicks, and because they're wider than I expected. I would prefer local pickup in TX but I am willing to ship if needed. Retail is $575 per tire. Asking $500 shipped for all 4 or best offer, obviously cheaper if picked up.
