Abstract: A tread pattern on a pneumatic tire is provided in regions of two intermediate land portions and has circumferential shallow grooves extending in the tire circumferential direction. An orientation of a groove inclination inclined with respect to a first direction in the tire circumferential direction of lug grooves provided in a region of one intermediate land portion, is the same as an orientation of a groove inclination inclined with respect to a second direction opposite to of the first direction of the tire circumferential direction of lug grooves provided in a region of another intermediate land portion, and the lug grooves provided in the respective regions of the intermediate land portions are bent so that the groove inclination approaches the tire circumferential direction at positions of intersection with the circumferential shallow grooves.

Abstract: A pneumatic tire includes at least four circumferential main grooves that extend in a tire circumferential direction; and at least five land portions defined by the circumferential main grooves. The center land portion and the left and right second land portions each include through lug grooves that are inclined at a predetermined inclination angle with respect to the tire lateral direction and extend through the land portion in the tire lateral direction. The through lug grooves located in the center land portion and the through lug grooves located in the left and right second land portions extend in the tire lateral direction inclined in opposite directions to each other. At least one groove wall of each of the through lug grooves located in the left and right second land portions include a step-shaped bent portion that bends in the tire circumferential direction in a plan view of a tread.

Abstract: A pneumatic tire includes: a main groove extending in a tire circumferential direction disposed on a shoulder region of a tread portion; lug grooves extending from the main groove toward an outer side and reaching a side wall portion; and blocks demarcated by the main groove and lug grooves. An edge on an innermost side in a tire radial direction of the blocks is positioned more on an outer side in the tire radial direction than a tire maximum width position, and a ratio of an orthogonal distance from a ground contact end position to the edge on an innermost side in the tire radial direction of the blocks is 0.2 or more. Recessed portions each having a closed periphery are provided in a side region more on an outer side in a tire width direction than the ground contact end of the blocks.

Abstract: The side wall portion of this pneumatic tire has a pattern visibly distinguished from the surrounding region. The pattern has: a first pattern element region at which are formed a pair of first reduced regions, which are provided on a line linking a pair of corners in a first demarcated section containing a pair of corners that are opposite each other, and a first primary region, which is visibly distinguished from the first reduced regions; and a second pattern element region at which are formed a pair of second reduced regions, which have the same unevenness or light reflection characteristics as the first primary region and are provided on a line linking a pair of corners in a second demarcated section containing a pair of corners that are opposite each other, and a second primary region, which has the same unevenness or light reflection characteristics as the first reduced region.

Abstract: A pneumatic tire includes four main grooves defining a central land portion, intermediate land portions, and outer land portions. Compound grooves including lateral grooves communicate with the main groove and terminate inside a land portion, and including sipes extending from the lateral grooves to the main groove, are formed at an interval in the tire-circumferential direction in the central land portion or an intermediate land portion. An opening direction of the lateral grooves relative to the main grooves alternatingly reverses in the tire circumferential direction. The lateral grooves include a broad width portion that opens to the main groove and extends at a constant groove width, and a narrow width portion positioned between the broad width portion and the sipe and extends at a constant groove width narrower than the broad width portion.
