Abstract: A pneumatic tire includes a block defined by first and second main grooves and first and second lateral grooves, wherein the block includes a slit having one end open to the first main groove and the other end terminating in the block, a first corrugated sipe having one end open to the first main groove and the other end terminating in the block, and a second corrugated sipe having one end open to the second main groove and the other end terminating in the block, the slit includes a notch groove and a center sipe, the center sipe includes a first portion extending from the notch groove toward the second main groove, and a second portion bent and extending from a terminal end of the first portion, and the first and second corrugated sipe are disposed in the tire circumferential direction across the center sipe.

Abstract: The tire is provided which has secured a traction performance in the side surface of the tire while showing a cut resistance property on the side surface of the tire. The tire includes a side block arranged on a side surface of the tire. The side block includes: a first block 11 formed on the side surface, the first block protruded from a tire surface 5 at a first height; a second block 12 formed on the side surface, the second block protruded from the tire surface at a second height different from the first height; a third block 13 formed on the side surface, the third block protruded from the tire surface at a third height different from the second height; and a fourth block 14 formed on the side surface, the fourth block protruded from the tire surface at a fourth height different from the third height.

Abstract: A pneumatic tire includes a block formed by a main groove extending in a tire circumferential direction and a lateral groove extending in a tire width direction. The block includes a first inclined surface provided at a corner portion between a first side surface and a top surface, the first inclined surface extending obliquely toward a groove bottom of the main groove or the lateral groove defined by the first side surface, and a first narrow groove extending from a center of the block toward the first side surface, an outer end of the first narrow groove being located on the first inclined surface, the first narrow groove being smaller in groove width than the main groove and the lateral groove.

Abstract: A pneumatic tire includes a block formed by a main groove extending in a tire circumferential direction and a lateral groove extending in a tire width direction. The block includes a depression depressed from a top surface to have a triangular pyramid shape, and a first narrow groove, a second narrow groove, and a third narrow groove provided radially extending from the depression, the first narrow groove, the second narrow groove, and the third narrow groove being smaller in groove width than the main groove and the lateral groove. The first narrow groove extends from the depression to a first side surface of the block that defines a second main groove. The second narrow groove and the third narrow groove are located at a distance from and are not connected to the depression.
