Well, everyone had us worried to death about our G670s on the rear.
13 years old. Pulled them off this spring. Soft and supple inside and out but only 36,000 miles or so. Of course it is stored indoors and the tires are kept clean. Did have some sunblock put on in 07. some may still be on them.
Michelin says their tires are warranted for 5 years.
Goodyears RV tires were for 10 years. We heard everything in between though. Now the Dealers say there is no established limit, however they won't buy them back for casings after five years.
Someone with a Semi is running our old tires today. They will wear them out in a year, carrying the heavy load, I'm sure.
I sure could have used the four thousand dollars for something else like a new boat.
AND we put our jacks down, in storage, on coated concrete, inside. Always have. Factory recommended it
