I'm one of the club fixit guys, and I got a little obsessed with the task of mounting a tire on a Tost 3" dia. solid tailwheel. I tried all the good advice offered on this and other forums with zero success. Most likely I lack superhuman hand strength and three extra arms.

Success took the form of a $43 Harbor Freight mini-tire changer and Ru-Glyde tire mounting lubricant from NAPA Auto. It's not as easy as the harbor freight promotional video:

but it isn't a hideous trial either. With the tool the most difficult part is getting the inner tube emplaced and managing the valve stem.

PS, If you used the tool regularly you'd probably make some modifications, since it theoretically is for wheels 4" dia. and greater.

PPS, I bought a split wheel for my own glider. Expensive, but you have some recourse if you get a flat when away from the shop.
