We have bought defenders for a GMC acadia and 2 sets of defenders for our dually 2 WD chebby truck. Drove to wash st in december 2 winters from Az. Bad road winter conditions both times and never spun a tire. Lots of michelin tires have had crack issues for years including MH's. We have had none. The 1st set was rated for 70K on the truck be replaced them at 50L. Nice even wear but tread was getting thin. I don't try to exend the miles because of towing. 50K was the warranty on the 2nd set. Nothing like fresh tires.
Still waiting for a tire issue for us. Been driving for 62 years 'LUCKY'
