Abstract
A structurally supported tire includes a ground contacting annular tread portion, an annular hoop structure for supporting a load on the tire, and a ply structure secured to a vehicle rim and the tread portion. The hoop structure is secured to a radially inner surface of the ply structure. The hoop structure includes a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords.
Claims14
A structurally supported tire comprising
- a ground contacting annular tread portion;
- an annular hoop structure for supporting a load on the tire, the hoop structure including a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords;
- and
- a ply structure secured to a vehicle rim and the tread portion, the hoop structure being secured to a radially inner surface of the ply structure.
The structurally supported tire as set forth in claim 7 wherein the second double layer of steel cords extend at an angle of between −5° to +5° relative to the circumferential direction of the tire.
The structurally supported tire as set forth in claim 8 wherein the single layer of steel cords absorb shear strain between the first double layer and the second double layer.
The structurally supported tire as set forth in claim 9 wherein the first layer of non-woven reinforcement consists of a nylon material.
A structurally supported tire and rim assembly comprising
- a ground contacting annular tread portion;
- an annular hoop structure for supporting a load on a tire, the hoop structure including a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords;
- and
- a ply structure secured to a vehicle rim.
A structurally supported tire comprising
- a ground contacting annular tread portion;
- an annular hoop structure for supporting a load on a tire, the hoop structure including a first double layer of steel cords and a second double layer of steels cords sandwiching a first layer of non-woven reinforcement, a second layer of non-woven reinforcement, and a single layer of steel cords;
- and
- a ply structure secured to a first axial limit and extending radially outward to adjacent the hoop structure and further extending radially inward from adjacent the hoop structure to a second axial limit, the ply structure being secured to both the first axial limit and the second axial limit.
