    摘要： A pneumatic tire improved in on-ice performance and on-snow performance in good balance. The pneumatic tire includes a tread portion extending in a tire circumferential direction and forming a ring shape, a pair of sidewall portions on both sides of the tread portion, respectively, and a pair of bead portions on inner sides of the sidewall portions in a tire radial direction, respectively. The tread portion includes a plurality of longitudinal grooves extending in the tire circumferential direction and a plurality of lateral grooves extending in a tire width direction. The longitudinal and lateral grooves define a plurality of block rows each including a plurality of blocks. Each of the plurality of blocks included in at least one of the block rows includes at least three closed grooves including at least one first closed groove and at least one second closed groove.

    摘要： A pneumatic tire having a designated rotational direction is disclosed, wherein an entire area having a width 85% of a total tire width and a center area having a width 30% of the total tire width are defined in a tread portion. A center main groove is positioned on a tire equatorial line and extends in a tire circumferential direction. Subsidiary main grooves are positioned on two sides of the center main groove and extend in the tire circumferential direction. Angled and lateral grooves extend at an angle, in a direction opposite the rotational direction towards an outside in the tire width direction. Lateral grooves extend from each subsidiary main groove. Sub grooves extend from the lateral grooves towards the rotational direction. A total length of a block edge in the center area is from 40% to 60% of a total length of a block edge in the entire area.

    摘要： A pneumatic tire is described having a designated rotational direction, wherein drainage grooves in a tread portion are positioned on each side of a tire equatorial line extending at an angle in a direction opposite the rotational direction while curving towards an outside in the tire width direction. An inclination angle θ1 to the tire circumferential direction at the terminal center position of the leading side of the drainage grooves is from 0° to 45°, while an inclination angle θ4 to the tire circumferential direction at the terminal center position of the trailing side of the drainage grooves is from 65° to 90°. Land portions defined by a rib section continuously extend along the tire equatorial line and are further defined by a plurality of branched sections continuously extending and branched from the rib section towards the outside in the tire width direction.
