Centrifugal force. I've done it with a few different vehicles/tires and it's always worked. Below about 20mph it has no effect, tires are not spinning fast enough for the balancing media to 'stick' to the tire through a full rotation but at those speeds it doesn't matter anyways.

If you used solid media in these tires it won't work because of the tar. The BB's/powder would clump up and get stuck creating a heavy spot and throwing the tire out of balance even worse.

Centrifical force move the liquid to where it's most effective. In aircraft tires they use balancing patches put on the inside in the middle of the tread. The advantage to liquid is that you can't spin the balancing weights on the wheel and as a Tire wears it's point of balance does also. I wouldn't think you need more than a quart of fluid per Tire 2lbs is a lot when it's distributed along the tread on the inside. You need more weight the closer to the center of the hub you get

http://www.innovativebalancing.com/chart.htm#CommercialChart This chart will get you a more accurate volume for using this type of balancing. I didn't find this chart until afterwards. For the 14x20 and 16x20 the chart calls for 16oz of weight for balancing media per tire, and 14oz for a 12.5x20.

So roughly a pint should be suffecient

any specific coolant?

( mostly wondering if there is anything to be avoided due to potential damage to rubber)

I just used the typical green coolant.
