At 38,000 these tires had no business on the wet icey, or snowy roads. Lucky for me, we had an extremely dry winter, spring and summer. I just hit 48,500 and have worried ever since hitting 38,000. I should have just replaced them but thought I could make it to 50,000 if we didn't have a wet season. I got lucky and will never risk that again. At 38,000 miles I was driving in less than an inch of snow. I took a turn, one I have taken many many times, and I lost the car. I was headed straight for a stop sign. I barely squeaked by with no injury to the car. However, on dry pavement these babies are quiet and so smooth. No vibration up to 95(I haven;t pushed it any higher than that). The guy at the tire place told me 15,000 miles ago that these tires were done. Guess not. I won't buy these tires again but I will buy the Primacy version.
