Abstract

A method of balancing a wheel assembly is achieved by providing a wheel assembly which includes a tire in a range substantially between 13" and 24.5" size, providing pulverulent polymeric/copolymeric synthetic plastic material in a range substantially between 8-12 screen size and 40-200 screen size, and placing a selected screen size range of the pulverulent material in free movable relationship to the tire in a weight range substantially between 1/2 ounce to 24 ounces for the tire size ranges of substantially between 13" to 24.5" size.

4. The wheel assembly balancing and radial and lateral load force variation equalizing method as defined in claim 1 wherein the step of placing the pulverulent material in free movable relationship is performed by placing the pulverulent material in the tire through a tire valve of the tire, and the pulverulent material is placed in he tire through the tire valve while the tire is pressured.

5. The wheel assembly balancing and radial and lateral load force variation equalizing method as defined in claim 1 wherein the step of placing the pulverulent material in free movable relationship is performed by placing the pulverulent material in the tire through a tire valve of the tire, the tire is pressurized during the performance of the placing step, and the placing step is performed by injecting the pulverulent material into the tire at a pressure greater than that of the pressurized tire.
