A system includes a wheel, a tire, a plurality of pressurized load cells and a sleeve member. The wheel includes a first flange portion, a second flange portion and a barrel portion positioned between the first and second flange portions. The tire is mounted to the wheel. The wheel and the tire cooperate to define a tire cavity. The tire includes a first beaded portion and a second beaded portion. The plurality of pressurized load cells are positioned within the tire cavity. The sleeve member is positioned within the tire cavity and surrounds and constrains the plurality of pressurized load cells.

A valve for air chambers includes a fixed body and a mobile selector body, wherein the mobile selector body is disposed coaxially in the fixed body. The mobile selector body is configured to slide with respect to the fixed body. The mobile selector body has a first position of use, associated during use to at least a first outlet, and a second position of use, associated during use to at least a second outlet.

Tire assembly for a bicycle rim, including a wheel tire with a tread surface and two tire beads, an inner tire disposed within the wheel tire, a tube disposed within the inner tire, and a valve arrangement for filling the tube and an intermediate space between the rim and the wheel tire with different air pressures. The inner tire in the filled and mounted condition bears on the tire beads of the wheel tire and presses the beads against the rim. The inner tire has a first through opening which in the mounted condition communicates with the intermediate space, and an insert part disposed between the rim and the tube and between the tube and the inner tire. The insert part forms an air duct between the rim and the tube and between the tube and the inner tire up to the through opening in the inner tire.
