Grandpa sold Coopers because he made a better profit. They are fine for an everyday car or SUV. But, don't expect them to perform on a sports car, is all I am saying. I own a set, but I don't race the Tahoe....Summer tires are going to wear out, and wear out fast if you drive the car hard. A/S will give you better mileage and less performance. Can't have it both ways. Good luck...with whatever you decide...
