When buying our 2007 Dynasty, it had early 2006 Goodyears all around. The dealer offered to get us a dealer price on tires, but the shop wasn4t able to find any Michelins at the time. I was offered 5 different brands, but chose the Toyos you are looking at. They were also the shop's recommendation as the best tire, and they were the best price. Taxes in, they cost me $4500 for 8, installed. I only drove this coach about 10 miles on the GY, so no valid comparison there, but compared to the ride of my old Contessa 38, the ride of this coach on those Toyos is superb. So good my wife has slept in her backseat driver's chair. That never happened in the Beaver.
If you are buying because of time, rather than wear, you won't wear these out, so don't need the extra expense of the Michelins.
