  • Method of installing an inflating tube within a tire
    Patent number: 7284327
    Abstract: A valve stem puller which comprises a length of flexible elongated member which is connected at one end to a ring and at an opposite end to an externally threaded plug. The valve stem puller is to be utilized by inserting such through a fastener nut and then through a valve stem mounting hole in a tire rim and then threadably connecting the externally threaded plug onto a valve stem of an inflating tube and then inserting the inflating tube about the tire rim and within the confines of the tire, pulling on the flexible elongated member to cause the valve stem to connect with the valve stem mounting hole in a close conforming manner. A fastening nut is then threadably mounted about the valve stem to secure such in position. The tire is then completely installed on the tire rim and the externally threaded plug is then removed from the valve stem.
