Method of and apparatus for introducing pulverulent material into a tire for the purpose of balancing a tire and an associated wheel assembly. A quantity of polymeric pulverulent material sufficient to balance a tire and an associated wheel assembly is charged to a cylindrical chamber and confined therein. Pressurized air is passed through the chamber in such manner as to form cyclonic air currents in the chamber. The cyclonic air currents can be obtained by configuring the air inlet and the air outlet for the chamber so that their respective axes are not aligned. A mixture of air and pulverulent material is withdrawn from the chamber and passed to a tire which is being balanced. An apparatus for practicing this method comprises a container having a transparent cylindrical side wall and a pair of end caps which together enclose a chamber for pulverulent material; an in-line filter, a pressure regulator and a first on-off valve which together form an air supply flow path for supplying air under pressure to the chamber, and a second on-off valve and a flexible hose having a quick disconnect coupling at its discharge end for conveying a mixture of pressurized air and pulverulent material from the chamber to a tire.

A method of introducing a pulverulent solid material into a tire through a tire valve stem comprising the steps of: (a) confining a predetermined amount of pulverulent polymer is solid material in an upright chamber having opposite first and second ends and having an air inlet at said first end and an air outlet at said second end, said air outlet being higher than said air inlet, said air inlet and said air outlet having non-aligned axes whereby cyclonic air currents are created; (b) passing a pressurized air stream successively through said air inlet, said chamber and said air outlet, said pressurized air stream flowing upwardly through said chamber and said air outlet, the pressurized air creating cyclonic air currents within the chamber and thereby creating an essentially uniform admixture of said pulverulent material and air; and (c) introducing the resulting admixture of said pulverulent material and air into a tire through an associated tire valve stem under the influence of the pressurized cyclonic air currents, the amount of pulverulent material so introduced into the tire being sufficient to effect dynamic balancing of said tire and a wheel assembly associated therewith but insufficient to substantially fill said tire.
