The emergency tire support device for a low air pressure tire includes an elongate belt formed by three layers of material that protects and supports a deflated tire. The belt wraps around the tire and is secured thereto by fasteners. The three layers include an outer layer of cloth, an inner layer of plastic, and an intermediate layer of cloth. A plurality of tacks extends through the inner layer, and the intermediate layer sandwiches the head of the tacks between the inner and intermediate layers. The tacks pierce the tread area of the tire as the tire rolls over the belt during installation, causing the belt to automatically wrap around the tire. The tacks also prevent slip. The inner and intermediate layers are stitched onto the first layer to form a plurality of longitudinal pockets. The pockets are filled with scrap rubber.

1. A emergency tire support device for a low air pressure tire, comprising: a flexible elongate, multi-ply belt adapted for wrapping around a tread area of the tire with low air pressure, the belt having at least one fastener at opposite ends thereof for securing the belt around the tire;a plurality of tacks extending through a ply of the multi-ply belt, the tacks being disposed on an inner face of the belt for piercing engagement with the tread area, each of the tacks having a head; anda layer of rubber scraps disposed within the multi-ply belt, the layer of rubber scraps adding thickness to the belt in order to compensate for reduced dimensions of the deflated tire and resiliency to simulate the normal resiliency of the tire tread. 2. The emergency tire support device for low air pressure tire according to claim 1, wherein said multi-ply belt comprises: an elongate outer, first layer;an elongate inner, second layer, said tacks extending through the second layer; andan elongate intermediate, third layer disposed between the inner and outer layers, the intermediate layer being connected to the inner layer to thereby sandwich the heads of said tacks therebetween, the inner and intermediate layers being attached to the outer layer by at least one elongate seam to form at least one longitudinal pocket between the outer and intermediate layers, the at least one longitudinal pocket being filled with said scrap rubber and extending substantially the length of said belt. 3. The emergency tire support device for low air pressure tire according to claim 2, wherein said outer layer is made from cloth. 4. The emergency tire support device for low air pressure tire according to claim 2, wherein said inner layer is made from plastic. 5. The emergency tire support device for low air pressure tire according to claim 2, wherein said intermediate layer is made from cloth. 6. The emergency tire support device for low air pressure tire according to claim 2, wherein said scrap rubber comprises tire scraps. 7. The emergency tire support device for low air pressure tire according to claim 2, wherein said at least one seam comprises at least two spaced seams of stitching between said outer, inner and intermediate layers, the two seams forming said at least one longitudinal pocket. 8. The emergency tire support device for low air pressure tire according to claim 2, comprising stitching connecting said outer, inner and intermediate layers to each other. 9. A emergency tire support device for a low air pressure tire, comprising: a flexible, multi-layer belt adapted for wrapping around a tread area of the tire with low air pressure, the belt having at least one fastener at opposite ends thereof for securing the belt around the tire, the belt having a first outer layer, a second inner layer and a third intermediate layer;a plurality of tacks extending through the inner layer, the tacks extending from an inner face of the belt for piercing engagement with the tread area, each of the tacks having a head, the intermediate layer sandwiching the heads between the inner layer and the intermediate layer; anda layer of rubber scraps disposed between at least two layers of the belt, the layer of rubber scraps adding thickness to the belt in order to compensate for reduced dimensions of the deflated tire and adding resiliency to simulate the normal resiliency of the tire tread. 10. The emergency tire support device for low air pressure tire according to claim 9, comprising at least two seams extending between said outer, inner and intermediate layers, the seams forming at least one longitudinal pocket between said outer and intermediate layers, the at least one longitudinal pocket being filled with said layer of rubber scraps and extending substantially the length of said belt. 11. The emergency tire support device for low air pressure tire according to claim 9, wherein said outer layer is made from cloth. 12. The emergency tire support device for low air pressure tire according to claim 9, wherein said inner layer is made from plastic. 13. The emergency tire support device for low air pressure tire according to claim 9, wherein said intermediate layer is made from cloth.
