PURPOSE:To make improvements in durability and steering stability, by setting up a belt layer using a carbon fiber cord at the carcass side while a belt layer using a steel cord at the side of a tread part, respectively, and bending an end part of the belt layer at the tread side to the side of the tread part, consti tuting the belt layer. CONSTITUTION:Belt layers 5d composed of a carbon fiber cord C is set up at the carcass side,while belt layers 5u composed of a steel cord S is set up at the side of a tread part 3. And, an end part of at least one layer of these belt layers 5u is bent to the side of the tread part 3, constituting a belt layer 5. With this constitution, durability and steering stability both are improvable. |
