Re: Bottle Jacks and changing tires
I went with the bottle jack/jack stand from alltradetools that Herb mentioned, and it is great, at least for practicing in the driveway. It has a broad base and is very stable, plus as a shallow "U" head that sits well on the axle. I'm sure it will work well under primitive road conditions. The only drawback is that the 3 ton jackstand weighs nearly 3 tons. It fits in my under floor storage compartment too.
