Even though my Uncle worked for Goodyear, I have only bought cars with them on. I am more prone to purchase Continental Tires over most others. At the dealership, they almost always put Coopers on the cars that need tires.
I guess I was uninformed, I was under the impression that Goodyear made good tires. I've never owned a set myself, but I did have some Cooper tires on a previous vehicle and they didn't give me any problems.
