摘要： PURPOSE:To improve the durability of a pneumatic tire with an organic fiber carcass ply by providing a short fiber containing rubber reinforcing layer inside the carcass ply that is adjacent to a stiffner. CONSTITUTION:A rubber reinforcing layer 13 containing the five parts or more by weight of the short fiber made of thermoplastic polymer with 0.2-1.0mm thicknesses, less than 1mum average diameter, and the ratio of the average length L to the average diameter D exceeding 8 or more is arranged between the adjacent cord layers 5a-5c of the inside section 6b of a carcass ply 6 that is adjacent to a stiffner 10. The short fiber orientation direction of this rubber reinforcing layer 113 is set to 0-10 deg. for the cord orientation direction of the carcass play 6. Besides, the 50% distortion modulus of elasticity when the reinforcing rubber is pulled in the short fiber orientation direction is set to 2.5 times or more the vertical modulus of elasticity and 1.5 times or more the modulus of elasticity of ply coating rubber. As a result of this structure, the durability of a pneumatic tire can be improved.
