The first 40k was fine. Started having trouble with balancing. Got an alignment and fine balancing. Problem never went away. Dealer could see nothing wrong. Rotated until the "problem" was on the rear and drive was tolerable. At about 60k the tires felt very hard and were very noisy. Started spinning in light rain and very dangerous cornering. Had to dump them for this winter because they would have been very dangerous in the snow. Surprisingly plenty of tread left. Would not buy again or recommend.
