In a tire, a tire outer diameter OD is in a range 200 mmOD660 mm. A total tire width SW is in a range 100 mmSW400 mm. A carcass layer is formed by layering two layers of carcass plies formed by covering organic fiber cords with coating rubbers. The organic fiber cords of the two layers of the carcass plies have cord angles in a range of 80 degrees or more and 100 degrees or less with respect to a tire circumferential direction.
