A pneumatic tire comprising a carcass toroidally extending between a pair of bead portions , at least one inclined belt layer arranged passing through a tire equator (CL) outward in the tire radial direction of a crown portion of the carcass , and having a cord extending inclined at an angle of 30° or more with respect to a tire circumferential direction, and a tread arranged outward in the tire radial direction of the inclined belt layer, wherein at least one circumferential cord layer having a cord extending along the tire circumferential direction is arranged inward in the tire radial direction of the tread , the circumferential cord layer has a high-rigidity region which is a region including the tire equator (CL) and in which the rigidity in the tire circumferential direction per unit width in the tire width direction is high, and a low-rigidity region which is a region on each side in the tire width direction of the high-rigidity region and in which the rigidity in the tire circumferential direction per unit width in the tire width direction is low, and the high-rigidity region has a higher negative ratio in a ground contact width of the tread than the low-rigidity region, characterized in that : when W1 denotes a width in the tire width direction of the entire circumferential cord layer , W2 denotes a width in the tire width direction of the high-rigidity region, and D1 and D2 respectively denote the longer and the shorter among the distances in the tire width direction from each end in the tire width direction of the entire circumferential cord layer to each end in the tire width direction of the high-rigidity region on a side close to each end in the tire width direction of the circumferential cord layer, W2/W1 = 0.2 to 0.7, and, D1/D2 = 2.0 to 8.0 are satisfied. at least one circumferential cord layer having a cord extending along the tire circumferential direction is arranged inward in the tire radial direction of the tread , the circumferential cord layer has a high-rigidity region which is a region including the tire equator (CL) and in which the rigidity in the tire circumferential direction per unit width in the tire width direction is high, and a low-rigidity region which is a region on each side in the tire width direction of the high-rigidity region and in which the rigidity in the tire circumferential direction per unit width in the tire width direction is low, and the high-rigidity region has a higher negative ratio in a ground contact width of the tread than the low-rigidity region, characterized in that : when W1 denotes a width in the tire width direction of the entire circumferential cord layer , W2 denotes a width in the tire width direction of the high-rigidity region, and D1 and D2 respectively denote the longer and the shorter among the distances in the tire width direction from each end in the tire width direction of the entire circumferential cord layer to each end in the tire width direction of the high-rigidity region on a side close to each end in the tire width direction of the circumferential cord layer, W2/W1 = 0.2 to 0.7, and, D1/D2 = 2.0 to 8.0 are satisfied. when W1 denotes a width in the tire width direction of the entire circumferential cord layer , W2 denotes a width in the tire width direction of the high-rigidity region, and D1 and D2 respectively denote the longer and the shorter among the distances in the tire width direction from each end in the tire width direction of the entire circumferential cord layer to each end in the tire width direction of the high-rigidity region on a side close to each end in the tire width direction of the circumferential cord layer, W2/W1 = 0.2 to 0.7, and, D1/D2 = 2.0 to 8.0 are satisfied. <EOS>
