  • Pneumatic tire reinforced with fabric
    Patent number: 4744401
    Abstract: A pneumatic tire containing a ply having a knitting fabric which is formed by arranging warps parallel to each other, setting wefts on the warps to cross the warps at an angle of 60.degree. to 90.degree. without weaving, and twining fine knitting yarns around the warps and the wefts. The ply is used as a chafer, a bead filler or a carcass of a bias tire and reinforces the pneumatic tire. The pneumatic tire is excellent in uniformity and durability, and the weight and the cost of the tire can be reduced.
