Radial-ply tires

摘要: This invention relates to radial-ply tires having a reinforcing belt located below the tread. With view improving lateral stability and resistance at high speed rubber strip of modulus elasticity is applied sides carcass over part only radial dimension or height tire so that said adheres carcass, being made from rubbery mixture elasticity, not less than 40kg/cm2 100 percent elongation which incorporates least 40 parts carbon black 35 fine polyolefine powder such as polyethylene, molecular weight greater 500,000. The extends bead beyond middle section 2/3 side, remaining side between upper edge coated with lower in order form supple bending zone.
