Went with Toyo Tires
Boyle908 is correct on the GY's IMHO. Not sure about Michelin's for the coach but I have used them for all of my passenger cars and pick up truck. Being Newbies we bought our coach, 2003 Bounder, last February and looked at the tires which were GY's. They had great tread and no signs of sidewall issues. But my experience with GY's on other vehicles including airplanes should have told me to replace them at first opportunity. Boy was I in error but was also watched over. We lit out for Florida, spring training, and on the way down, BOOM, blew the RH inside rear. No problem as the truck stop tire store had a used same size and make. We put her on and 200 miles later, BOOM, there she blows. Called emergency tire man and he brings a new tire. He looks at the old tire and nods, tells me I should expect the others to blow anytime soon because of the DOT Date Code. I had no idea. He had no other tires to fit. What to do? Drive no more than 55 and pray you make it to your planned campground, he says. Then get the rest replaced ASAP. OK, we take it easy - no more than 50 - but there she blows! LH Rear inside. Time to shut down, get new tires, be safe, and not sorry. We were blessed that there was no damage to the coach after the 3 blowouts. Bought 6 new Toyo's that are made in USA (couldn't get Michelin's), put the emergency tire in the spare rack, traveled 500 miles back home from Fla, and put 6000 miles on our summer trip with no more tire issues. Don't know if the Toyo's are the best but they will do for now. I do swear by the Michelin tire brand for my other vehicles including the airplanes.
