ABSTRACT:
A non-pneumatic tire for mounting on a rim having axially spaced annular mounting flanges. The tire is formed with a radially exterior tread surface having axially outwardly sloped side walls projecting radially inwardly therefrom and formed on their radially inwardly extremities with shoulders that nest against the radially outward edges of the mounting flanges. Retaining flanges then project radially inwardly therefrom for retention on the axially inner sides of the mounting flanges. The tread surface and opposite side walls cooperate to form a circumferential interior cavity which a latticework of webbing formed by axially extending interrupter webs which are spaced equidistance about such cavity and have an annular projecting circumferentially thereabout and connected with such axially projecting interrupter webs. The tread, sidewalls, flanges and webbing are all preferably constructed of resilient elastic material such as polyurethane and has a circumferential length approximately 10% less than the circumferential distance around the rim to thus provide an elastic constraining force after being stretched over the rim. Also, elastic endless belts or beads may be embedded in the retaining flanges to provide further securing force maintaining the tire on such rim.
