I'm in the "waste of time camp" too....

That said, if I were "hell bent to do it anyway", rather than jack up the trailer over and over all winter, I'd be inclined to jack it up once in the fall, invest in jack stands and just leave the tires off the ground. That way, you can walk out and 'spin 'em every day" if that's what gives you jollies. It just seems a waste of significant time and effort to repeatedly jack the trailer all winter, usually in inclement, messy conditions. Jack it up once, block the frame and not worry about it for the rest of the storage season...

But then, being in the "waste of time camp" like A.E. Newman, "What, me worry?"
