Abstract

A pneumatic tire includes an axis of rotation, a carcass having at least one reinforced ply and a reinforcing structure providing a buffer for absorbing shear strain, a tread disposed radially outward of the carcass, and a belt structure disposed radially between the carcass and the tread. The reinforcing structure includes at least one layer of a three dimensional fabric including a frame structure of fabric and open cells defined by the frame structure.

First claim

What is claimed is:

1 . A pneumatic tire having an axis of rotation, the pneumatic tire comprising:
a carcass having at least one reinforced ply and a reinforcing structure providing a buffer for absorbing shear strain; a tread disposed radially outward of the carcass; and a belt structure disposed radially between the carcass and the tread, the reinforcing structure comprising at least one layer of a three dimensional fabric including a frame structure of fabric and open cells defined by the frame structure.

2 . The pneumatic tire of claim 1 wherein the reinforcing structure is a flipper.

3 . The pneumatic tire of claim 2 wherein the flipper separates the reinforced ply from a bead of the carcass.

4 . The pneumatic tire of claim 3 wherein the flipper acts as a strain-relieving layer between the bead and the reinforced ply.

5 . The pneumatic tire of claim 1 wherein the fabric has warp yarns of 940/1 dtex polyaramide and weft yarns of 1220/1 dtex rayon.

6 . The pneumatic tire of claim 5 wherein the warp yarns have a density of 14 EPI and the weft yarns have a density of 12 EPI.

7 . The pneumatic tire of claim 1 wherein the fabric has warp yarns with a density of 14 EPI and weft yarns have a density of 12 EPI.

8 . The pneumatic tire of claim 1 wherein the pneumatic tire is a radial runflat passenger tire.

9 . The pneumatic tire of claim 1 wherein the pneumatic tire is a high performance tire.

10 . The pneumatic tire of claim 1 wherein the fabric comprises an open weave tape.

11 . The pneumatic tire of claim 10 wherein outside edges of the open weave tape has a pair of warp yarns continuous for the radial length of the open weave tape.

12 . The pneumatic tire of claim 11 wherein the open weave tape further comprises an adhesion promoter disposed thereon.

13 . The pneumatic tire of claim 1 wherein the reinforcing structure is a flipper having two or more layers of open weave tape.

14 . The pneumatic tire of claim 13 wherein the flipper includes warp yarns of at least two fibers of different fiber materials.
