charges me about $25/tire to mount and balanced a tire on a rim. It would be
nice to be able to swap in and out my own tires when the need arises.

Unless your shop uses some kind of dynamic spin balancer, you can do yours
at home and with a little practice get as good or better results than many tire
shops. Just rig up something to hold an axle suspended horizontally. You can
make a double forked metal fixture, but I find that two identical milk crates
with notches work well enough for the occasional balancing. Mount the tires
according to the colored dots / valve stem ( varies according to brand ) Make
sure wheel bearings are lubed and in good shape. Give the wheel a spin and note
where it stops. Mark the top. Spin again and see if it stops in the same spot.
If so, you have probably found the light part of the assembly. Repeat a few
times to confirm. The closer to exactly the same stopping spot, the heavier the
bottom is. If it stops in generally the same area but not exactly, its not far
off. If you're lucky and it stops in completely random spots, its balanced. Add
some tire weight at the top spot. Spin some more,adding and subtracting weight
on the light spot, until randomness is achieved. Remount wheel, test ride,
enjoy well deserved barley pop.
