I had tires put on my car. The tires are vey good, but after they were changed my sensors don’t work. I feel that the sensors should still work even after they were the tires were changed.

Wonderful tire and prices so well. We have 13 cars and I have always used Michelin just for the safety of having the best tires made. I am about to replace another set for my CL63 because I had such a good experience on my M6. Wonderful grip, comparable to Continental contact extreme, which is better than Michelin, yet still a bargain
