I have their Goodrich tires (owned by Michelin) and they've been fine so far but they are the all Terrain T/A tires and I don't have 35K on them yet. Michelins usually get good reviews but I know that they have had some recalls recently, my Goodrich tires were just all replaced at about 18K.
This one for exampleI'd google michellin recalls with your tire type to check.
I do suggest that you go out and buy yourself a 12 ton or more bottle jack, you need it for your fifth wheel anyway. Carry a piece of wood to put under the jack so it doesn't get pushed into the dirt when you use it. A 18 inch length of 2X8 or wider or an equivalent piece of 3/4 inch plywood works well. The jack they include with all vehicles are **** since they stopped making bumper jacks.
