I bought a 3 ton jack that does the trick quickly for wheel changes. 60 seconds to lift a corner is certainly quite doable without much exertion. Probably a stretch though to get all the wheels off in 30 seconds. If I had torqued them myself, maybe in a couple of minutes. I use a hand torque wrench to put them on properly. The shop guys go to town though with their g-d impact wrenches. ) However, I wouldn't trust myself enough to properly get it safely on stands where I would feel comfortable working under it, though.
