Dollies are cool for moving it, but once moved, lower it onto the tires.
Increase Tire pressure to 59PSI (per Owners Manual) and allow it to sit for the season.
Modern Tires, with synthetic cording - nylon, kevlar, etc., will not permanently flat spot.
Admittedly, back in the reign of Geo. 1st, when tires were purely Steel belted, flat spotting was an issue.
But, with the advent of synthetic cording, flat spotting (if it occurs) will dissapate the first time the tires come up to temp - these new materials do not possess a permanent memory.
In other words, in the interim, it has succumb to the Demon marketers of tire pads, tire dollies, and the like, taking advantage of fears established in past generations of tires which simply are NOT applicable to today's tire engineering.
