I have two large pneumatic cylinders and I can raise my fiver up and put it on jackstands in under five minutes. I tried keeping it off the ground during storage for several years and that didn't make the ST go pop tires last a bit longer. I even had one of those go pop tires blowout over the winter while it was off the ground and covered. After two sets of go pops in a row only lasted four years, almost to the month of manufacture, I switched to ST tires.
I'm going to store my fiver off the ground again because I can do it so easy. I've also read that the air pressure can be let down when the tires are stored with no load on them. Craig
