I bought these tires and originally thought they rode good, then started to cup badly on the rear. I had the alignment checked, tires balanced and no change. The ride is unbearable, the left rear is concave in the center of the tire and unsafe on the highway. These tires have a high treadwear rating, but it is inaccurate. The fronts have 18k miles and tread wear indicators are visible. The rears have plenty of tread, but have badly cupped and one is concave. I contacted the manufacturer but I have been given the run around. Not good tires, I DO NOT RECOMMEND THEM!
9000 miles and I have been told by several people that I need to start looking at replacing them. Even the dealer said that they need replacing. REALLY 9000 miles ??? That means I will be replacing tires every year... something is wrong !!!!
