Interesting to note that the Michelin folks at the last BB RIV at Perry
Fairgrounds said that they have changed their guidelines to 10 years for RV
tires, provided they are inspected continuously for cracks not to exceed 1/32".
Also said absolutely no tire shine or any other rubber dressing to be used,
cover tires when not on the road to block UV.

First of this year, replaced six Michelin 315/85R22.5 XZA which were original
equipment on our coach. Just had some barely visible hairline cracks. Date
coded 1999. Another note, these tires had been run with Nitrogen, which
eliminates moisture inside the tire.
