ABSTRACT:
A vehicle wheel-tire assembly wherein the tire has a low inflation pressure (large tire footprint) in a low vehicle speed range, and a large inflation pressure (small tire footprint) in a high vehicle speed range. The tire is partitioned into a series of circumferential compartments, with each compartment being provided with a valve mechanism for introducing air into the compartment and/or withdrawing air from the compartment as needed to maintain desired inflation pressures in the different vehicle speed ranges. The system is contained entirely in the wheel-tire assembly; no external air compressors or control valves are utilized.
