Thanks tp all~
I did find the sticker with tire data. It was inside the cabinet over the sofa in the slide out. I purchased the correct tires, but they are Cooper tires--not Michelins. That is the difference.
The front tires were inflated to 65 lbs, rear 80 lbs. The installer asked me and I checked after them to be sure. I just don't get the sure-footed response that I did from the Michelin tires. :-( I actually get nervous sometimes where I was confident before.
I appreciate the information on the Michelin OEM tires; that is exactly what I was looking for!
I will check pressures again when the tire covers come off in May. And will drive it again this year with these tires to evaluate their performance further. I'll probably have to drive 5-10 mph slower to feel confident again. We'll see.
