I live in Abilene. TX and about 90 miles away from here is the largest Goodyear Proving Grounds in the United States. I heard from a friend that your able to register your car, get a set of new wheels hooked up on your vehicle and test them for Goodyear. Now I dont know if this is true, but I would personally like to have a brand new set of tires to tear up on a 5 mile testing track for the day.
