Use automatic levelors during storage?

I lower the levelers on my coach just to take off some of the weight off. I park my coach on a concrete drive way, sometimes up to three months and do not worry about putting plywood or rubber or what ever between the concrete and the tire. The only thing that I know that does damage tires is the sun. That is why it is important to keep the UV rays off. The sun will destroy just about anything if exposed for long periods at a time.
Do not lift your tires completely off the ground.
