    Abstract: In a pneumatic tire, a belt layer includes an inner-side cross belt and an outer-side cross belt having an absolute value of belt angle with respect to a tire circumferential direction of not less than 46 degrees and not more than 80 degrees and having belt angles with signs that are opposite to each other; and a circumferential reinforcing layer having a belt angle with respect to the tire circumferential direction within the range of ±5 degrees and disposed between the inner-side cross belt and outer-side cross belt. Also, a distance Gcc on a tire equatorial plane from a tread profile to a tire inner circumferential surface and a distance Gsh from a tread edge to the tire inner circumferential surface satisfy a relationship 1.10≦Gsh/Gcc.

    Abstract: A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. The belt layer includes an angle belt having a belt angle ≥45° and ≤70° in absolute values, a pair of cross belts having belt angles of ≥10° and ≤45° in absolute values and having belt angles of mutually opposite signs, and a reinforcing layer having a belt angle within ±5° relative to a circumferential direction. A width Ws of the reinforcing layer and a cross-sectional width Wca of the carcass layer satisfy 0.60≤Ws/Wca≤0.70. The cross belts are radially outward of the large angle belt. The reinforcing layer is radially outward of the pair of cross belts. A width Wb2 of a wider cross belt of the pair and Wca satisfy 0.79≤Wb2/Wca≤0.89.

    Abstract: A pneumatic tire includes: a rib defined by a circumferential main groove; circumferential sipes formed in the rib at intervals in the circumferential direction; rib edge sipes formed in the rib aligning in the circumferential direction, each of the rib edge sipes terminating in the rib opening to the circumferential main groove; and first and second narrow grooves extending in the circumferential direction, each of the first and second narrow grooves having a groove depth shallower than depths of the circumferential sipes and the rib edge sipes, the first narrow grooves having ends connected to one of the circumferential sipes adjacent to each other in the circumferential direction and the second narrow grooves each including an inner connecting portion connected to one of the first narrow shallow grooves and including an outer connecting portion connected to one of the rib edge sipes.

    Abstract: In a pneumatic tire are defined: a first line VL1 passing through a ground contact surface in a cross-section of a tread, a second line VL2 passing through a bottom of a shoulder groove and parallel to VL1, an intersection P between tVL2 and a surface of a shoulder land outward of a ground contact edge T in a lateral direction, and an equatorial plane CL. Given A as a distance in the lateral direction between P and CL, B as a depth of the shoulder groove, and C as a distance between T and CL, 0.80≤(B+C)/A≤1.15 is satisfied. Given J as an outer diameter in the equatorial plane, K as an outer diameter of an opening end inward of the shoulder groove, and L as an outer diameter at T, 0.05≤(K−L)/(J−L)≤0.85 is satisfied.

    Abstract: The present technology provides a heavy duty pneumatic tire with a tread portion having a tread pattern including: a pair of circumferential primary grooves defined in a wave-like shape and extending in the tire circumferential direction; center lug grooves; center blocks; and circumferential secondary grooves extending in regions of the center blocks and open to the center lug grooves. The center lug grooves have two groove turning portions turned in a bend shape or a curved shape. The circumferential secondary grooves extend in an inclined manner relative to the tire circumferential direction. An inclination angle (θ4) of the circumferential secondary grooves relative to the tire circumferential direction is different from an inclination angle (θ1) of portions of the circumferential primary grooves relative to the tire circumferential direction, the portions extending toward the same side as a side in the tire width direction, toward which the circumferential secondary grooves are inclined.
