Preps: Have two sets of matching rims/tires in your inventory. Ideally no other rims, cause after disassembling, both parts are put at the end of your inventory. And it's not fun to scroll every time you wanna assemble a wheel through all the 200 rims you have. For me to just give you the "optimized combo", have an assembled, but unbalanced wheel and a balanced wheel in your inventory.
How to: At this point you shouldn't need an explanation of the mechanics, so I just lay out the "combo" (WB = Wheel Balancer, TC = Tire Changer):
1. WB: Select "Balance" -> press Enter 2x
2. TC: Disassemble -> Enter 2x -> Remove
3. TC: Assemble -> Enter 3x
4. WB: Remove
5. TC: Remove
6. goto 1
Depending on your training and skill you should be able to balance ~3 - 4 wheels per minute.
