A few years ago, I bought a new set of tires and my local “friendly dealer” charged me over $100 to mount tires I bought from them. I already knew I could have bought the tires for $100 less on line, so a +$200 experience!
I bought a set of spoons (really strong, polished, long ones), rim protectors, valve stem lanyard, and a wheel balancing/ rim truing stand (total: about $200). Since then, I’ve been building my own wheels, mounting and balancing new tires, etc.
Yesterday, I had to remove a 15+ year old tire from a nice alloy rim. The shop was cold, and so was the impossibly hard tire. Here’s a really good short cut: fitted a 1” fibre cutting wheel to my high speed Dremel Tool. Using the rim protectors and two tire irons, pop the tire bead over one side of the rim. I cut a two inch wide strip of sheet steel (very thin) and slid it under the bead to protect the rim. Using the Dremel, I cut through the wire cable, buried in the rim. This smokes and stinks, but only takes a minute. The steel cable sparks on the cutting wheel. When the sparks stop, your through. It pops about a 1” long slice in the bead and you can see it pop and spread a good bit. Flip the tire, and repeat on the other side. Lube the beads and proceed as usual. Took about two minutes to pop a tire that would have been impossible otherwise......
Works a treat! Good Luck!!
