My vette came with these tires and I must say, they are not that bad. However, I won't be buying another set because the price is very high compared to other tires. But keep in mind people, run flat tires are good for everyday driving which I do and I know if I get a flat that it will not tare my fender up which is a plus. These tire have a good life especially considering I drive my vette only like once or twice a week and take it to shows and sometmes to the drag track. Not bad at the drag track but, it is no radial tire. I would recommend to buy these once and see how you like it. The only reason I will not be buying is because my car will get a increase in 100+ hp and I know I will need a better tire. thanks.
