A system and a method provide a coating on an interior surface of a tire. A valve connects to the interior of the tire. The method connects a source of coating material to the valve, propels the coating material through the valve, and applies the coating material to the interior of the tire. The system has a source of a coating material connected to the valve. A propellant causes delivery of the coating material through the valve into the tire. Another method coats an interior of a tire mounted on a rim. The method connects a first end of a tube to a source of coating material and inserts the second end of the tube into the interior of the tire encircling the rim. The coating material moves through the tube into the tire. The tube is withdrawn from the tire moving along the interior circumference of the tire.
