We had Michelin tires on a 27 ft Winnebago class A motorhome. They had dry rot cracks on the sidewalls. They were less than 3 years old with less than 12,000 miles. The motorhome was parked under cover on gravel. The tires were not covered, were not aired up to maximum, and motorhome was not moved for the last year owned.
Our current class C motorhome has Michelin tires that are five years old with 33,000 miles and have no dry rot on sidewalls. The motorhome is store inside, on concrete, driven every two months or less, driven at 65 mph or less in hot and cold weather, aired to maximum psi on rear dual tires, and weight is under GAWR and GVWR.
Maybe just a coincidence?
