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.
