Bougth these tires based on my dealer's recommendation. I started complaining about the noise and the vibrations to the car dealership and they recommended an alignment to rectify the uneven wear. The car passed with flying colour! Everything is fine with the wheel alignment.They checked the suspension as well as the wheel bearing, but everything is good! We are now trying to get some warranty money's from the wholeseller. At almost $200. per, one would expect to get more than 30K on tires!
