What I have heard is that one should replace their tires every 7 years, even if they still look good. And, that 7 years should be based on the "manufacture date" that is stamped on the tire itself.

It is not unusual for a tire to sit in a warehouse of a distributer or dealer for some time before being mounted on a new unit. For that reason, I've been told that when purchasing replacement tires that one should be sure and check the manufacture date on the new tires before actually having them installed.

Many times the issues above don't affect vehicles because the all tend to get enough mileage in a few years time to not worry about the manufacture date. But, with an RV that doesn't get as many miles, it can be a problem.
