Air bags during storage for winter

[Lee Welbanks]

Lee,
Might want to consider rotating the tires every so often to spread out the wear and stress. That should give you 7 year life easily.

Not in the cards now since I replace the fronts in Utah after the big boom. We used to move steer tires back, but never drive tires up front mainly because of difference in tread.

Ok, to clarify to the op's original question, I have, for eleven years, been putting oak blocks under my 2  coaches and dumping the air so the coach sits on the blocks and takes the weight off of the tire sidewalls. I have not been running the same tires for eleven years. I hope that clears things up. Also, in some cases you can not rotate tires front to rear and vise versa because a lot of newer coaches run a different tire size up front due to axle capacity. Marty
