PURPOSE:To make improvements in durability and steering stability, by layering a carcass side belt layer composed of a steel cord and a tread side belt layer composed of a carbon fiber, while constituting the belt layer in a way of turning over an end part of the carcass side belt layer so as to cover an end part of the tread side belt layer. CONSTITUTION:Belt layers 5d composed of a steel cord S is set up at the side of a carcass layer 4, while belt layers 5u composed of a carbon fiber cord C is set up at the side of a tread part 3. And, an end part of at least one layer of these belt layers 5d at the carcass side is bent 5d1 to the side of the tread part 3, covering an end part of these belt layers 5u at the tread side, thus a belt layer 5 is constituted. With this constitution, improvements in durability and steering stability both are well promoted. |
