I'm stealing this, rim protection has always been a problem for my clumsy self with street tires and tire irons.I use automotive fuel injection hose as a protector.
I slice it length wise about 6 inches and then slip it over the rim lip.
Cheap, easy, and works.
Occasionally have had one be stubborn but lube and more pressure has always done it. Is it not sealing at all or is it sealing against the bump towards the center of the wheel and not popping out against the bead seating area?Dang. Still can't get the beads to seat. Pretty annoying. Anybody else have issues seating the bead?
If you have enough flow capacity sometimes taking the core out of the valve stem will help get enough air in fast enough to seat everything.
