Static Balance
Also known as "bubble balancing" uses a fairly inexpensive machine to balance the wheel/tire assembly at rest using a bubble level as an indicator. This technique takes some operator skill to perform good balancing as you need to carefully split the balancing weights on the inside and outside of the wheel to avoid dynamic imbalance.

Dynamic Balance
Also known as "spin balancing" can be done either on or off the vehicle. The majority of tires are probably balanced on computerized spin balancers. After clamping the wheel on the machine, setting the wheel dimensions, it spins up and calculates the locations and amount of weight to apply to the rim to correct the balance. Most spin balancers center the wheel on a cone-shaped mounting device. This works fine for vehicles that locate the wheel on the vehicle via the hub (i.e. "hub-centric"). For vehicles, like Toyota, that locate the wheel on the hub via the lug nuts (i.e. "lug-centric") a special lug-centric adapter should be used to properly balance the wheel. On vehicle balancers avoid this problem, spinning up the wheel in place.

We've always insisted on dynamic balancing, high speed, so we won't get the vibrations on the highway.
