Tire pressure monitor installation tool

A tire pressure monitor (TPM) installation tool adapted for use by an operator, with a TPM having a valve stem and a circuitry housing connected to a distal end of the stem, and with a wheel defining a valve stem hole configured to receive a portion of the stem, wherein the tool is configured to install the TPM, so as to assemble the TPM and wheel and provide mechanical advantage, said tool comprising:

• an elongated member presenting first and second distal ends and having a manual grip section adjacent the first distal end and a nesting fixture connected to the second end;
• a wheel engaging member coupled to the elongated member and configured to secure at least a portion of the tool to the wheel;
• and
• a mechanical advantage element configured to receive an applied force from the operator, multiply the applied force by a factor to generate a resultant force, and transmit the resultant force to the TPM during installation,
• said nesting fixture being adjustably connected to the elongated member, so as to present one of a plurality of tool configurations, and configured to engage the housing and retain the TPM in a fixed position relative to the fixture during installation,
• said nesting fixture, elongated member, and wheel engaging members being cooperatively configured such that during installation the stem is inserted in the hole by the resultant force,
• said valve stem and circuitry housing being connected by a fastener, said nesting fixture and TPM being cooperatively configured so as to transmit the resultant force solely through the fastener during assembly.
