  • a hollow stem having a distal end and a proximal end, the stem including an enlarged dome formed on the proximal end and defining a dome shoulder facing distally for engaging a wheel rim, the dome having a dome height extending proximally from the dome shoulder;

    the stem including a longitudinal bore extending along a longitudinal axis from the distal end partially into the enlarged dome, and the stem further including a plurality of open lateral bores configured to fluidly communicate the longitudinal bore with an outer surface of the enlarged dome when the mounting stem is mounted on the wheel rim, the lateral bores having lateral bore diameters at least 25% of the dome height, and each lateral bore having a lateral bore axis oriented perpendicular to the longitudinal axis and located closer to the proximal end than to the dome shoulder; and
