Do the old style bubble balancer work

[grumppyoldman]

If you decide to have them spin balanced, be sure the have the equipment that ROAD LOAD balances. Discount Tire in my area has changed all their's to do this. It applies a load on the tire like it was being driven on the road, As far as finding on that spin balances the tire on the car I haven't seen nor could find one any where ion my area. Bubble balance does not do dynamic balance which is the best, Iv'e balanced steam turbine rotors with modern dynamic machines, and the turn 10,000 rpm. Al
