RADIAL TIRE FOR TRUCK AND BUS TO IMPROVE DURABILITY

摘要

PURPOSE: A radial tire is provided to prevent the separation by inserting a cord of solider material than a rubber between a second belt cord layer and a third belt cord layer. CONSTITUTION: A fabric cord(6) is inserted in a space between a second belt cord layer(3_b) and a third belt cord layer(3_c) among belt cord layers(3). The fabric cord has an inclination within -20 ¯ 20 degrees. The fabric cord has the inclination of 0 degree desirably. Thereby, the separation of the second belt cord layer and the third belt core layer is prevented. Therefore, the life of a tire is extended.
