I recommend you start a written log on the tires, include the date installed, location on the RV (right, left, front, back, spare). Why?? On our Monty, we travel about 4000 miles each summer and in storage the other 8-9 months. Sitting still IMO really does damage to the tires--yes I cover mine also. My guide is NO tires on the RV that are over 3 years old. Sure reduces tire failures and gives me piece of mind. I still have Coach Net roadside service, carry a 140psi air compressor, 12 ton hydralic jack, & torque wrenches.
