Any tire manufacturer will tell you if the the DOT code is over three years old it can not be sold as a new tire. Also anything over 6 years old should be changed as the tire is starting to degrade. This is from tire manufacturers and not me.
Michelin states that the tire should be inspected at 5 years and each year up to 10 years at which time they recommend replacing the tire.
What manufacturer states that the tires should be replaced at 6 years?
Here's the quote from Michelins Service Life for RV/Motorhome Tires:
"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.
For tires that were on an original equipment vehicle (i.e., acquired by the consumer on a new vehicle), follow the vehicle manufacturer’s tire replacement recommendations, when specified (but not to exceed 10 years)."
