VAR also makes a tire-jack that functions the same way as the Kool Stop tire-jack. One half of the tool grabs the rim on the side you have one bead already seated on (the easy part). Then the other half of the tool straddles the tire and grabs that last part of the tire that refuses to go on. This side has a hook that slips under the stubborn bead. Pull the lever back - *POP!* The tire is on.
