Abstract
A tire changer has a base on which is mounted a rim and tire assembly support table upon which tires are inflated through an air inflation hose. A rigid arm-like member is pivotally attached to the base of the tire changer in a position so that it may be pivoted between a safety position overlying the support table and a rim/tire assembly thereon and a stowed position away from the support table. In one embodiment the rigid arm pivots from an overhead position to the safety position and in another embodiment the rigid arm pivots from a lateral position to the safety position. The rigid arm carries the air inflation hose with a short length of the hose extending therefrom, so the arm must overlie the support table for the hose to reach the inflation valve on a tire supported on the table.
