I have always been a fan of Michelin. Until now. I have had them for about 2 years with a little over 30k miles in them. They have never been a smooth, comfortable ride (which is what I expect from a Michelin tire) and were never quiet. But recently the noise has become obnoxious. Another reviewer described the noise similar to mud tires on a truck. I have to agree. They are wearing on the edges, even with religious rotating and alignments. Terrible tire especially for what I paid for them. Michelin has lost a 25 year loyal customer because of the Defender.
