Aha yeah one hi-lift can do some types of useful work that floor jacks are just not usable for... floor jacks are for flat ground, hi-lift is great for bad terrain and creative use since it can also be used as a poor man's winch, crane et cetera. Might have solved that problem in a few minutes with one and a bit of luck :) If ya didn't care about cosmetics of the rims it'd be as simple as sticking the jaw into the rim on each tire, jack up, fill under, lower down, x4... but it's less of a story that way ;)
