The rod had two conical shaped attachments that screwed up against both inner races. The outer ends of the rod had bearings that rested between two tripods. After setting the wheel in the jig the tire's heavy end spun down and by trial and error, he was able to stick on the exact weight onto the rim to balance it. I have seen these wheel balancers I think, in Aircraft Tool Supply company catalogs. I rolled out the tire over a yard stick and found it only rolls 34 inches to complete one revolution. If you factor in how many revolutions that tire makes between 65 mph and even 20 mph, it wouldn't surprise me if the four ounces out of balance my wheel was and considering centrifugal force dynamics, that four ounces could factor out to be several hundred pounds of out of balance force. t In a message dated 4/15/2010 4:10:27 P.M.
