PNEUMATIC TIRE

A pneumatic tire of the present disclosure includes, on a tread surface, circumferential main grooves extending in a tire circumferential direction and land portions defined between circumferential main grooves adjacent in a tire width direction among the circumferential main grooves or by the circumferential main grooves and tread edges. The land portions include widthwise grooves extending in the tire width direction and are divided into blocks by the widthwise grooves. At least one widthwise sipe extending in the tire width direction is included within the blocks. Hard rubber with a higher elastic modulus than that of tread rubber is disposed in a tire radial region including at least an opening to the tread surface of a wall defining the widthwise sipe. Microfabrication is applied in a region of the tread surface surrounding at least a portion of the opening of the widthwise sipe to the tread surface.
