Here is the process that was used for the last tire balancing on my car. It feels rock solid with a very quiet steering wheel.
********************************************
- Remove the wheel and tire assembly from the car, and dynamically balance it using a Hunter GSP9700, or Roadforce Variation Machine
- If applicable, index, or turn, the tire on the wheel to ensure the assembly is round when rolling
- Apply the necessary weight to perfectly balance the wheel and tire assembly
- Install the balanced wheel and tire assembly on the car using hand tools (no air-guns here)
- Hand torque lugs or bolts to manufacturer specifications
- Using our Hofmann finish-balancing machine to spin the non-drive wheels (i.e. front wheels on a rear-wheel drive car), and the motor of the car to spin the drive wheels, we run the wheel and tire assembly up to 120 miles per hour!
- Minute measurements and adjustments are made to the balancing weights to ensure that the wheel and tire is perfectly matched to the hub of the car at all speeds

I was a little uneasy watching my drive wheels turning at over 100 MPH while the car was off the ground. The value of vehicle these guys regularly work on far exceeds that of my old C4 so that helped my comfort level. The option I did pass on was Nitrogen for the tires.
