I own a corvette . High speed tires are designed to be able to handle higher speeds without breaking up and coming apart. It is very important for sport cars but is not imperative for the normal driving vehicle. A major drawback is that I pay about $300.00 per tire for my tires. They are very soft rubber, and they wear out fast. They are better for traction and high speed turns, but get ready to pay for them. Good luck, and do not spend the money if they are not needed. My car is set-up for speeds up to 175MPH. Most cars are not, and do not waste your money!!
