Class A tires

When my rig is parked I keep covers on my tires. Before each time I drive it, I wash it and treat my tires with a spray on protectant.

With that said:

Do you replace the tires based on age, wear or sidewall condition?

My tires are 5 years old, have under 2000 miles on them and look new.

If I need to replace them based on age, what is a good, safe brand that is sold at a reasonable price?


Tire size is a 22.5 and camper is a 22,000 pound unit.
  • I had a blowout R/F on a 6 year Michelin. It had just been inspected by a dealer and it still looked brand new, with 70,000 miles. There was NO dry rot or cracks. It just goes to show (Rose-Anna Anna Dana)
  • I think most tire companies say you should have them inspected by a qualified professional for breakdown ("dry rot") starting at around seven years and replace in any case at ten years. Of course, if there is some obvious reason why replacement is needed sooner, like treadwear or sidewall damage, then do that.
  • I've read a lot of folks say 5-7 years. However, Michelin themselves suggest 10 years (well taken care of and inspected).
