I replaced the rear tube at work after showing up with a stem-washer-left-in-the-tire induced flat.
Bike on center stand, pull axel, remove spacer, tilt bike onto thighs while doing a partial squat, pull out tire.
I put it on the floor and broke the bead by pushing on the side wall with the butt of a mallet handle. Did both sides. Used the spoons in the kit and they did not bend and worked fine. You only have to go a few dozen degrees around the rim and then it pretty much can be wrestled off by hand. Just flipped off one side of the tire
Pulled out old tube and replaced. Put a little air in it so I knew where it was and started pushing the freed edge of the tire back on with my hands for a while, then went back to pushing with the mallet handle finishing up the last few degrees with the spoon. Made sure valve was straight, filled tire to reset bead, let air out to desired pressure, put on the stem washer and nut.
Tilted bike onto my lap again, slipped tire under fender, replaced spacer and axel, tightened things up then washed my hands.
20 minutes or so I think. Ahhh.
