Abstract
Abstract A vehicle tire includes a rubber or elastomer tire body which has a circumferentially extending crown portion and opposite sidewalls joining the crown portion. The sidewalls terminate in circumferentially extending beads adapted to be received in a vehicle wheel rim. A plurality of circumferentially spaced arcuate leaf springs are, at their ends, resiliently embedded into the respective beads. The leaf springs support parts of the internal face of the crown portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
A vehicle tire comprising (a) a tire body of a material selected from the group consisting of rubber and an elastomer; said tire body including (1) a circumferentially extending crown portion having an external face and an internal face; (2) circumferentially extending first and second sidewalls joining said crown portion; said first and second sidewalls terminating in circumferentially extending first and second beads, respectively; said first and second beads being adapted to be received in a vehicle wheel rim; and (3) a plurality of circumferentially spaced stiffening ribs; each said rib interconnecting said crown portion and said first and second sidewalls; and (b) a plurality of circumferentially spaced arcuate leaf springs each having opposite first and second ends resiliently embedded into respective said first and second beads; said leaf springs supporting said ribs at rib surfaces forming part of said internal face of said crown portion.
Claim 2
Dependent Claim
146 words
A vehicle tire comprising (a) a tire body of a material selected from the group consisting of rubber and an elastomer; said tire body including (1) a circumferentially extending crown portion having an external face and an internal face; (2) circumferentially extending first and second sidewalls joining said crown portion; said first and second sidewalls terminating in circumferentially extending first and second beads, respectively; said first and second beads being adapted to be received in a vehicle wheel rim; and (3) a plurality of circumferentially spaced stiffening ribs; each said rib interconnecting said crown portion and said first and second sidewalls; and (b) a plurality of circumferentially spaced arcuate leaf springs each having opposite first and second ends resiliently embedded into respective said first and second beads; said leaf springs supporting said ribs at rib surfaces forming part of said internal face of said crown portion.
Claim 3
Dependent Claim
80 words
The vehicle tire as defined in claim 1 , wherein said tire body has a central symmetry plane, said crown portion has a crown line and each said stiffening rib has a central line; further wherein said center line of each said stiffening rib forms an angle with said crown line; in said symmetry plane said angle being α=90° and viewed toward said side walls from said symmetry plane said angle decreasing to α 1 , wherein 60°<α 1 <90°.
Claim 4
Dependent Claim
79 words
The vehicle tire as defined in claim 1 , wherein said vehicle tire has a center of gravity, an axis of rotation and a symmetry plane oriented perpendicularly to said axis of rotation and each said stiffening rib has a central line; said stiffening ribs being uniformly spaced from one another; imaginary planes containing said center of gravity and said center line of respective said stiffening ribs form identical angles β with said symmetry plane; and further wherein 60°<β<120°.
