I've been on two wheels for well over 50 years ... During that time many different scooters and dozens of different tire brands ... I can't recall ever having an issue caused by a scooter sitting on it's tires in the garage
Oh my how did we ever survive before we had the internet to give us all kind of silly *** stuff to worry about.
Flat spots on your tires that have just been sitting for a few months is going to be a non-issue! If your still gonna' be **** about the non-issue, just roll the bike forward or backward a few inches each month.
I have a nice jack and a lift table. I don't store bikes on either of them. For most maintenance/service I don't need them either (tires/shocks are two tasks that the jack or table make a lot easier).
That display stand (turntable?) probably cost more than both my table and jack.
I have several of the jacks like @Omaha posted above, got them off Amazon for dirt cheap... not the same brand but it is really hard to screw up a scissors jack
One of the wide ones is sufficient, or two of the narrow ones
My local Craig'sList has 9 for sale now. All different brands. The most expensive is a $180. Sears, yellow jack. Looks brand new.
I've been happy with my HF. I just keep summer (warm) air in the tires, no issues in a heated garage.
I raise my Heritage up with my HF jack and put homemade 4x4 blocks under the frame to keep the tires off the floor.
Maybe it's unnecessary, but I do it because I can!
I got on Craigslist, and set up a search for a jack/lift. It took about eight months to get the right one, but I scored a J&S for $250 in perfect working condition.
Couldn't bring myself to pay the $900+/- on a new J&S.
