I have Sumitomo ST 719 tires, which I had the Les Schwab folks in Gridley, CA put on the morning after we bought the coach. They are 11R22.5. They will age out before they wear out with our limited driving each year.
I don't recall exactly what rpm I see at 60 mph. I think around 1700-1750. Will check it a week from next Monday when I drive the coach over to a shop for an oil change. I do know that at 60 mph with cruise control on I feel like we are just floating along with no stress.

I've got 22.5 tires, and at 60 mph I'm around 1800 RPM's....give, or take.

Not sure of the model number, but it is a 5 speed just like Glenn's. I do have the manual, so I'll have to pull it out and verify the model number. I'll let you know for sure.

Mike, my 1984 has an Allison MT654 5 speed transmission. Don't know about Clarke's.
