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.

First claim

What is claimed:

1. 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.

2. The structurally supported tire as set forth in claim 1 wherein inner radii of the ply structure are attached to the vehicle rim through two mechanical clamps each capturing a part of the ply structure.

3. The structurally supported tire as set forth in claim 1 wherein the first double layer of steel cords extend at an angle of between −5° to +5° relative to the circumferential direction of the tire.

4. 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.

5. The assembly as set forth in claim 4 wherein the ply structure includes a plurality of strips of material extending between the vehicle rim and adjacent the hoop structure.

6. The assembly as set forth in claim 4 wherein the ply structure consists of one single strip of material extending repeatedly between the vehicle rim and adjacent the hoop structure.

7. The assembly as set forth in claim 4 wherein the single layer of steel cords absorbs shear strain between the first double layer and the second double layer.
