ABSTRACT:
Safety apparatus for a tire changer having a support table for tire/rim assemblies and a tire inflation system includes a post having a quick disconnect mechanism for engagement with and release from the support table. The post has high pitch threads which receive a restraining cone with mating threads. The post is engaged with the table through a central rim opening and the restraining cone is moved on the threads to engage the edges of the rim opening. The post-table engagement actuates an air interlock which enables the tire inflation system. The cone is trapped on the post by structure on either end of the post.
