Michelin tires dry rot - Costco purchase

[Dennis H]

Is this just cosmetic? 3 years and about 12 thousand miles. Easy, shady life in mild climate. The model is Pilot. 235 55/18. 06 Charger. This model not on the recall list from Michelin as suv tires are.

What is the date code on the sidewall??? Look fot the DOT stamp and look at the four-digit number next to that.

Did Michelin or the Dealer pro-rate new tires? I notice now the Challenger has the same tires and rot. Coopers are nice on the 69, how about modern muscle. Good price.

We have been having a discussion over on the Garage Journal about Michelin tires dry rotting at a young age.

They are not alone. I've had Goodyear do the same thing.

Did you go back to Costco and bring up the issue. Might be late depending on DOT DATE but they stand behind their products.... For years. I'd give it a whirl.....

Does it sit for long periods outside? My truck tires do that after a year or two.

The new Challenger yes, covered and shaded carport. Charger is Linda's grocery getter.

Carport. Not even close to anything that generates ozone.

Michelin and Goodyear can pound sand. I put Coopers on. Cooper on everything I own. The 69 and modern Mopar too.

Michelin will probably say it's cosmetic, I've heard that pilots do that and I've seen other Michelin tires do the same thing although I did have a set of XCX truck tires on my Nissan 4x4 that Never gave me any problems and had 140,000 when my truck was hit in front of my house by an uninsured driver, that's a story for another time. I have always liked Michelin brand tires but like everything else their quality may not be the same anymore.

Hope you took those off ..I wouldn't drive on tires like that

Rubber compounds break down with time. Ozone and exterior influences just accelerate it. Any tire over 6 years old should be replaced. Most manufacturers recommend 4 years. The average mileage driven each year on s given set of tires is 15-20K . Less if you live outside the cities. 60K warranty on tires works out to 4 to 6 years of driving. Second cars and recreation vehicles see much less mileage, but time marches on. Rubber* actually there is very little actual rubber in a tire, mostly synthetic compounds* loses its elasticity with age. The compounds break down and the tire gets hard. Check out an old set of slicks. Because the tire is not actually round when the vehicles weight is being carried, the tire deforms in the rotation cycle, ( picture high speed racing tires that deform under acceleration ) It is the same as taking a piece of metal and bending it back and forth until it fails and breaks. At low speeds, like around town the life of the tire is a little longer but at highway speeds the tire heats up and centrifugal forces on the tire tread lead to an eventual separation of the belts. When this happens, there is usually a great deal of fender and body damage that occurs, and possibly a fatal accident. Unless it is for show, always inspect your tires for punctures, cracks, cuts etc..., check the air pressure and replace when questionable. I worked for Firestone during the tire recalls in 2000. Over 6 million tires replaced. We checked the air pressure on every vehicle that came in. The average tire was underinflated an average of 10lbs. The tires were built to Ford's engineers specs. The pressures were recommended by Ford. During the investigation it was found that there were several contributing causes for the tire failures. The pressures were recommended for a comfortable ride. During the years of the Ford Explorer's production the weight of the vehicle increased but Ford never revised the original air pressure recommendations. Even at recommended pressures, the tires were overloaded. Overloaded tires generate a lot of heat and together these variables lead to many tire failures. Not good. Follow good, common sense maintenance practices and be safe.
