I think $500.00 is a lot of money now days. I know that when I switched from Michelins to Toyo's, I saved something like $800.00 . It was the best move I could have made. I really like the Toyo's and at the time I noticed that all the Country Coaches had them out of the factory. So I figured if they are good enough for a high end coach like Country Coach, they are good enough for me.
I think you could get Toyo tires in the 245x65 22.5 for about the same as the Sumotomo's.

I got the Toyo's through Discount Tire Stores, but I am sure there are many that sell Toyo's. Here in California Petes Tire also sells them.
