Dont patch it plug it. Get the galvanized rubber plug kit at a autoparts store or Wal-Mart. Do it yourself. Kit costs like $4 bucks and is good for several repairs. I have Yokohama AVS Intermediates I think they are V-rated. Ive run em at auto-x events with one of the tires plugged so far so good. No leakage. Infact I got a screw stuck in one this week I plugged it. And Im racing on it on the 28th. Hope it holds. If not THEN Ill buy new tires.
