These tires were purchased to replace the original set that came on the vehicle. With my acceleration, cornering, and braking habits, I have never gotten more than 36,000 miles from a set of tires. We have always rotated our tires every other oil change (every 7,000 mile). These tires currently have 55,000 miles on them and they look like they will be good for another 10,000. This is the first set of tires I feel I have definitely gotten my money's worth.
