PROBLEM TO BE SOLVED: To improve stable maneuverability and comfortableness at the same time by placing a carcass auxiliary layer, which is formed by burying a lot of organic fiber cords into rubber, into a belt which is formed by burying many metallic cords arranged radially in parallel each other into rubber and by stacking the cords with circumferentially specified angle in the opposite direction. SOLUTION: This tire is equipped with a pair of right and left bead cores 1, a carcass 2 which is engaged with a right and left bead sections with being wound around the bead cores 1, and a belt 3 arranged radially outside of the crown section. The tire is formed with a pair of right and left radial cord layers which extend from the both bead sections to the both ends of the crown. In the belt 3, cord direction is inclined about 10-30 degree circumferentially of the tire, the cords are placed to be parallel with each other between layers, and distance between radial cord layers in the crown section is 5-70% of cross section width of the belt. A carcass auxiliary layer 4 which is formed by burying many polyester fiber cords in rubber is placed such that it is adjacent to the inside of the tire of the carcass 2. |
