I replaced mine at five years and the reason why I replaced the Michelins XRV was because it had small cracks on the side walls. Even though Michelin said they were OK, I didn't want to take a chance on a blowout. You don't have any miles on your coach, but have a tire shop check them out preferably one recommended by the manufacturer of the tires. I would think that those tires are still good, but have them checked out anyways. I replaced the Michelins with Toyo's and I really like them.
