On my last truck I had Michelins and yes they looked very dry rotted long before the tread wore out. I was worried bout them and was glad to sell the truck. That being said I did put Michelin LTX M-S2's on the trailer now and have BFG's on the truck. So we will see if newer Michelins will dry rot or not. I am in a prime location to test that with the Texas sun.
PS check back in 3-4 years and I will let you know how they are doing
