Tom, I concur with the last sentence in your comment about Michelin tires. My original statement about Michelin was not intending to "bad mouth Michelin", but only to provide information. However, after reading your comment I thought perhaps Michelin had changed it's policy. So, without intending to be argumentative, let me provide some more info.
Some years ago I took delivery of a Freightliner semi truck that came with 10 new Michelins. Within 5 months I lost 7 of the 10 tires, all from blow-outs on the sidewall. All of the seven Michelin dealers where the blow-outs occured, (in Texas, Colorado and New Mexico) informed me at the times that "there was no Michelin Warranty". ( I did complain after the seventh blow-out to Denver Freightliner, where I had bought the truck. Denver Freightliner, although the truck company does not warranty tires, did make it right with me.)
Since I have been a rancher since 1954 I have had and do own quite a number of tires of all types and makes. So I try to keep up with the latest info on equipment.
Last summer, at the Greeley, Colorado annual Farm Show, I discussed Michelin tires with the Michelin rep at the tire booth there. As of last summer, the Michelin tire rep there informed me that Michelin has never had a tire warranty. However, Just to see if Michelin has recently changed it's warranty policy, yesterday I called my farm tire dealer, TDS in Craig, Colorado. I was informed that TDS knows of no tire warranty by Michelin. Then, just to see if there might me a difference among dealers, I phoned the Wheatridge, Colorado TA Truckstop where I do business when in the Denver area with my semi. The Service Manager there infromed me that TA knows of no Warranty by Michelin for tires. The TA Service Manager gave me the phone number of the Michelin regional manager in Denver. I phoned the Denver regional Michelin Manager and was informed that Michelin has no warranty. However the manager informed me that on occasion, especially for fleet customers, when he is requested, he has in the past, and can at his discretion, make "adjustments" for tire problems involving Michelin tires. He stated that he will consider each case individually.
