Tires - The 10 Year Rule
Hey gang, Regarding big, DP tires... I know most adhere to this rule and some prefer to replace tires within 7 years or so of date code. Others replace the steers every 5 and the drives every 1...

Michelin guidelines.
1." Keep five years in mind
After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional.
2. Ten years is a maximum
If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator. This applies to spare tires as well".
That said, AGE is not as much a concern as how often the tires are used. Tires have emmolients(lube) in the rubber. When tires are regularly driven those emmolients stay distributed thru the entire rubber. When they SIT for long periods(trailers and Boat trailers more common), the emmolients dry out and cause certain areas of the rubber to dry and have small cracks thru the tread. So, if you have a 7 year old RV or CAR and have less than 10k miles on it, REPLACE THE TIRES AS THEY ARE NOT SAFE. I replace my 1975 Corvette tires every 7 years which only has 31k original miles. I don't want to risk a blow out caused by drying out of the tires. Doug
