Abstract
A pneumatic tire produced of elastomers, especially cast or injection molded polyurethanes has an inner body in which a reinforcement is embedded and anchored by means of holding ropes. The inner body may be provided as a closed tubular body and is encased by an outer body which accommodates a belt and is outwardly provided with a tread. At its side walls, the outer body is provided with respective bead cores in which area, the inner body of the tire is connected to the outer body.
Claims8
A reinforced side wall pneumatic tire comprising:
- an outer elastomeric tire body having a tread along its outer periphery, opposing side walls adjoining said tread, and respective beads along inner peripheries of said side walls;
- a bead core embedded in each of said beads;
- an inner elastomeric body embedded in said outer body along said tread and said side walls and in continuous contact therewith, the elastomer of said inner elastomeric body having a hardness and modulus of elasticity which are each less than the hardness and modulus of elasticity of the elastomer of said outer elastomeric body;
- a radial reinforcement embedded in said inner body and thereby incorporated in the tire as the side wall reinforcement thereof;
- and
- anchor elements embedded in said inner elastomeric body proximal to said beads and around which said radial reinforcement is looped.
