Abstract
Abstract A vehicle tire is disclosed herein having a central hub with attachment holes for wheel studs provided therein. The perphery of the hub is provided with an integral flange supporting a plurality of loops and spokes or braces arranged in spatial relationship about the entire circumference of the hub. A rubber or the like tire casing is carried over the plurality of loops or braces and the terminating edges and sides of the tire casing are vulcanized or otherwise bonded to the portion of the loops or braces and to the hub. Air is captured between the hub flange and inside surfaces of the tire casing so as to provide a soft vehicle tire reinforced by the loops and spokes or braces.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
202 words
A safety tire comprising the combination of: a wheel hub having a central opening for insertably receiving the end of an axle; said wheel hub further having a plurality of stud receiving openings arranged in a circular pattern coaxial with respect to said central axle opening; said wheel hub terminating in a circular flange extending outwardly from opposite sides of its circumferential periphery; brace means fixed to said flange and radiating outwardly therefrom; a flexible tire casing bonded to opposite sides of said flange and to said brace means so as to capture air between the interior of said tire and the opposing surface of said flange; said brace means includes a plurality of braces or spokes of substantially U-shaped configuration arranged in fixed spaced apart relationship; each of said braces comprises a pair of spatial legs outwardly supported from opposite sides of said flange and having the free ends of said legs joined by a cross member to complete said brace; said tire casing includes sides bonded to said opposite sides of said flange and to said brace legs with a substantial space separating said cross members from the internal opposing surface of a tread portion joining said tire sides together.
