The following is taken from the Michelin RV Tire Guide available on the Michelin web site:
"While most tires will need replacement before they
achieve 10 years, it is recommended that any tires in
service 10 years or more from the date of manufacture,
including spare tires, be replaced with new tires as a simple
precaution even if such tires appear serviceable and even if
they have not reached the legal wear limit."
Michelin recommends replacing tires at an age of 10 years regardless of how good they look. The age is from the date on the sidewall, not the in-service date. The biggest problem with RV tires is they usually sit for long periods of time. Driving them allows them to flex and bring UV and oxidation inhibitors to the surface where they can better protect the tires.
If the 2006 tires have been stored properly out of sunlight, you may get 5 years use out of them. But you could also get less. Although half price may seem like a bargain, you also have to add to that the cost of mounting and balancing, taxes, disposal fees, etc. If it were me, I would only buy those tires if I KNEW I were only going to keep the RV a couple of more years.
