Abstract: A method of filling a tire on a vehicle wheel with polyurethane foam comprises fitting the tire to the rim injecting liquid ingredient materials for the foam through an inlet opening in the rim closing the inlet opening revolving the wheel about a vertical axis to distribute the ingredients around the interior of the tire and when foam begins to escape through an outlet which is diametrically opposite to the inlet opening, closing a shut off valve at said outlet to prevent escape of further foam.
