I've had no issue with tire wear or traction with these tires. However, there has been vibration from these tires from day one. I've had it balanced and rebalanced. The tire shop said they put them on another machine to check for out of round and they were within spec limits. I've had the front end checked for worn steering parts or anything else that might cause vibration and nothing comes up. Funny that the vibration I complain about showed up about the same time I had these new tires installed. Will probably not buy these tires again. Road noise at 40k seems to be the same as any other tire I've had on the car. When they were new, they were nice and quiet, but I suspect after the quiet coating on the outer layer of the tire wears off, you get the same tire as any other competitor.
