Abstract
A semi-pneumatic tire body for assembly to the rim of a wheel comprises spaced tread and root portions interconnected with spaced sidewalls to define an annular cavity. An annular load-bearing rib is connected to the root portion and extends radially toward the tread portion to be normally spaced apart from the tread portion in the unloaded state in order to establish communication between the internal chambers of the tire for free gaseous interchange and for free response of the tire to load forces.
