I have PS2 from Mich. they are a great tire, they never squeal, and are very predictable in corners, I can easily sense when they are going to break loose. They will grip and grip real good, then if you keep pushing them hard in a corner they will slowly start to slide out. Some cheaper tires will not let you know this, or where the limit is until your hit their breaking point and wham! before you know it your spinning like a top. Michelin has done their rubber engineering on that tire. Thumbs up here!
