We cover ours when we are stationary for more than a week. A retired tire engineer at an Escapee Boot Camp convinced us that it was a good idea. The tire companies add things to protect against the sun but other things will remove it. When you park on concrete for long periods of time and don't put a plastic placemat or something under the tire you get a black mark on the concrete when you leave. According to the engineer that's the sunblock stuff that the concrete causes to leave the tire.
