I use these tires to drive to/from the track and on the track while I am there. I had been very pleased with the Bridgestone Potenza RE-11's that I previously had, and had heard that the Pilot Super Sports (PSS) were supposed to be even better, so I purchased a set when my RE-11's wore out. While the PSS's are a decent track tire, they do not have near the hold and stickiness that the RE-11's have. I was not able to hold the same line in the corners with the PSS's and the stopping distance in the back straight at Mid-Ohio was an extra 100-150 feet using the same brake pads (Pagid Yellows on front and Orange on rear). Overall, I was disappointed with the tires for track use. For street use, they are a very good, reasonably priced choice. If I am only looking for a street tire, I would strongly consider purchasing these again. For track use, I would definitely not.
