Waste of money. I purchased these tires about 6 months ago and wish I had done my homework. Tires were fine for the first 12k miles, regular rotations, kept tire pressure checked. Tread is standing up to highway miles, no uneven wear present, but the noise is driving me crazy. I know I'm going to go deaf from the hum off the tires. When I steer hard to one side and take the weight off the tires on the right side, quiet as a mouse. Noise is worst between 50 and 70 mph. Checked alignment, checked wheel bearings, all okay. I am going to spread the word on these awful tires.
