Abstract

A vehicle wheel, of the type that carries a tubed tire includes a wheel body, a rim which has a plurality of segmental rim parts, a solid retaining ring which engages all of the rim parts along one side thereof, cam and cam follower means between the rim parts and the wheel body which, when powered, urge the rim parts outwardly, and a power device connected to the wheel body which is capable of actuating the cam and cam follower to urge the rim parts radially outwardly into a final position, wherein there is established an equilibrium between the urging force applied to the rim parts from the power device, and, respectively, a restraining force applied to the rim parts by the ring due to its tensile stress.
