I balanced my own tires using jack stands and an extension.
I saw a few videos about balancing your own tires. I priced different placed and the total mounting and balancing was from $80 ~ $120. I found a regular tire shop that did the mount and disposal for $15/each total.
So I then needed to balance them.
I place two regular jack stands fully extended, put a 3/8" socket extension (about 12") thru the wheel and put it on the jack stands. Played around a bit to test how accurate it would be, then added a bit of 3N1 oil (light machine oil) on the extension.
Tested over and over, seems very accurate.
Removed all the weights, taped on various weights until I found the right amount and the right spot. Applied contact cement to a clean surface and reused some of the old weights. Applied equal amounts to both sides and double checked that it was balanced.
No special tools needed.
The light oil helps to keep it from sticking, testing in both directions, every few inches, helps to insure you have the right weight and spot.
I need to find some good Gaffers tape to go over the weights.
Harbor Freight sells a tool for this, but (IMO) you really don't need it.
