I had Michelin Harmony tires installed in mid November and the right front keeps losing air. I took the car in and they could not find anything. Previously, I had bought Uniroyal tires for my wife's car and within 6 months 1 had devolped a jagged break on the sidewall. I was told that it was a knive cut which would not be jagged. within the next 3 moths two more tires devolped the same problem.
I will not be back to buy tires. Their repair servive has been good but they do not stand behind their tires. This was at the bear canyon store.
