I recently had to fit a new rear tyre to my bike and came up with a simple cheap and very safe way of getting it off the ground. I just used a common ratchet tiedown under the rear tail piece (which is very strong) and up to a suitable lifting point (rafter or cross beam that will take the weight). You can lift as high as you want. I also used a trolly jack underneath to take the weight off the tiedown while waiting for the tyre to be fitted. You need to be careful letting it back down with someone steadying it, maybe onto some timber then rolling it off or lowering on the jack.
I had previously used just a trolly jack and found it very unsteady.
