The Michelin PR 3's and 4's are sport touring tires, I would not do track days with them even though you can be pretty aggressive with them on the street. Go with a sport tire for that. For the street, where you live with the dry climate, I would go with the PR 2's and save a good amount of money. The 3's and 4's are probably the best wet tire you can get which you don't need.
