Described are valve stems for wheels or other pressure vessels that may be installed from the exterior of a wheel or pressure vessel without access to the interior, pressure retaining areas. The valve stem may include a body with a barrel and taper. A neck may be between the body and a base that includes a flange, a flange landing, and an air aperture. An air channel runs vertically through the valve stem to allow air to pass from one side of the valve stem to another with a valve core or other flow control device. The base of the valve stem may include a groove that allows the valve stem to be installed into a hole by twisting such that the groove may ride along the rim of the hole and guide the valve stem into a fully seated and sealed position.

A tool is configured to install a tire pressure monitoring (TPM) sensor in a tire rim of a vehicle tire. The tool includes a lever having a rotational movement about a rotational axis; a cam selectively coupled to the lever; and a push pin selectively coupled to the cam. The cam translates the rotational movement of the lever into a liner or translational movement of the push pin. The linear or translational movement is effective to impact or move a roll pin of a tire pressure monitoring (TPM) sensor disposed at the tool, such that portions of the TPM sensor or pushed through an opening in a tire rim.

A valve puller is provided, including: a main body; at least one valve assembly, connected to the main body, configured to be connected with at least one valve head; and a support mechanism, including a connection portion and at least one support body, the connection portion being connected to the main body, the at least one support body being changeably connected with the connection portion, the at least one support body being configured to be abutted against a rim to serve as a fulcrum such that the main body is swingable relative to the rim.

A multipurpose tire tool for quickly and easily removing and inserting valve stem cores and sensors for a tire pressure monitoring system (TPMS). Such a tool has a central body with a proximal end and a distal end. The tool further includes a variety of elements used in the removal and insertion of valve stem cores and sensors associated with TPMS. These elements may include, but are not limited to, one or more Philips head screwdriver inserts or bits, a T-10 insert or bit, a valve a core replacement tool, and a tire air fitting. In practice, the tool may be oriented in any of a variety of fashions to quickly and easily be inserted into valve stems for the removal of valve stem cores and replacement of TPMS on a wheel of an automobile.

An auxiliary fixture for a tire pressure monitoring device has a handle, a positioning base, and a holding lever. The positioning base is connected to the handle and has a pivot segment and a clamping segment. The pivot segment is deposited on a rear side of the positioning base and is pivotally connected to the handle. The clamping segment is deposited on a front side of the positioning base, is connected to the pivot segment, and has two adjusting elements and a pushing pin. The adjusting elements are deposited on a front side of the clamping segment, and the pushing pin is deposited between the adjusting elements to press against the tire pressure monitoring device. A distance between the adjusting elements can be adjusted to enable the adjusting elements to clamp the tire pressure monitoring device. The holding lever is connected to the handle.
