Abstract:
A pneumatic tire includes a carcass layer, a belt layer that is disposed on the outer side in the tire radial direction of the carcass layer, and a tread rubber that is disposed on the outer side in the tire radial direction of the belt layer. The pneumatic tire also includes at least three circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions that are defined by these circumferential main grooves. The belt layer includes an inner-side cross belt and outer-side cross belt having belt angles of not less than 51° and not more than 80° as absolute values with respect to the tire circumferential direction, the belt angles having mutually opposite signs, and a circumferential reinforcing layer having a belt angle that satisfies a range of ±5° with respect to the tire circumferential direction.
