Webbed non-pneumatic tire

A non-pneumatic tire of the type to be mounted on a rim formed with an axially extending central rim and axially spaced apart annular mounting flanges comprising:

• a resilient circumferential tread wall having a radially outwardly facing tread surface;
• a pair of axially spaced apart resilient elastic side walls projecting radially inwardly from said tread wall and cooperating therewith to form a circumferential cavity, said sidewalls terminating at their radial inner edges in shoulders for seating on the radial edges of said mounting flanges;
• a pair of axially spaced apart elastic retaining flanges projecting radially inwardly from said respective sidewalls for being stretched over said rim mounting flanges and for receipt against the axially inner sides thereof, said retaining flanges terminating in radial inner edges spaced radially from axially extending surfaces of said rim;
• a plurality of radially projecting resilient webs spaced apart substantially equidistant about the circumference of said cavity, extending axially between said retaining flanges and said side walls and attached thereto throughout substantially the radial width of said retaining flanges and said side walls to yieldingly urge said retaining flanges axially outwardly into engagement with said respective mounting flanges;
• and,
• a single annular elastic stabilizing band disposed in said cavity, centrally between said sidewalls and of a circumference sufficient to be held under tension when said tire retaining flanges are mounted on said rim mounting flanges whereby said tire may be mounted on said rim with said retaining flanges retained between said mounting flanges and pushed thereagainst by said webs and when weight is applied to said rim while said tire rolls on a support surface said sidewalls will carry said weight and when said webs pass sequentially between said rim and support surface they will cooperate with said sidewalls to provide irregular support.
