Abstract: A mounting stem may receive an inflation valve and a tire pressure monitoring system sensor. The mounting stem may include a hollow stem including a distal end and a proximal end. The mounting stem may further include an enlarged dome formed on the proximal end and defining a dome shoulder facing distally for engaging a wheel rim. The dome may include a dome height extending proximally from the dome shoulder. The mounting stem may also include a longitudinal bore extending along a longitudinal axis from the distal end partially into the dome. A plurality of lateral bores may communicate the longitudinal bore with an outer surface of the dome, and may include lateral bore diameters at least 25% of the dome height. The lateral bores may be located closer to the proximal end than to the dome shoulder. The dome may also include a threaded TPMS mounting hole defined therein.
