does a tire bead 'jack' work? I'm having great difficulties getting a kevlar belted tire onto my rim (maybe I'm getting old).  I had heard about the Kool-Stop tire bead jack as a possible alternative to using just my tire levers. Has anyone used these things? Am I signing myself up for a pinch flat?
Interesting tool.  I haven't used one but can sympathize after breaking many tire levers with my old tire+rim combination.  It's no fun being in the middle of nowhere and snapping a lever while fixing a flat.  I've since switched tires (and later the rims) and can now roll the tires over the rim by hand -- what a difference!

Unless you plan on taking this tool with you on rides, you may want to look at tires that are easier to work with (if this one is new, you can probably exchange it at your LBS).  Otherwise a single flat could end your ride.

For beefy plastic levers, I'm now using a set of Pedro's.  They're about 3-4 times the size of the ones I had before and were strong enough to wrestle my bad old tires back onto the rim before I switched.

To avoid pinch getting flats while putting the tire back on, try putting a bit more air in the tube.  This will make it hug the inside of the tire instead of getting caught between the tire and the rim.
