Abstract: In a carcass (13), between first sections (13A) in which an inter-cord distance between a body portion and turn-back portions gradually decreases outward in a tire radial direction and second sections (13B) in which the inter-cord distance gradually increases, there are disposed first distance-invariant sections (13C) in which the turn-back portions (14B) are brought closer to the body portion (14A) that becomes a substantial bending neutral axis and in which the inter-cord distance is constant, so compressive force acting on the cords of the turn-back portions (14B) can be reduced. By disposing the first distance-invariant sections (13C) between the first sections (13A) and the second sections (13B), the direction of the cords of the turn-back portions (14B) is not suddenly changed, so it becomes difficult for stress to concentrate in the rubber between the cords of the turn-back portions (14B).

Abstract: The present invention provides a pneumatic tire in which the tread pattern is optimized to improve wear resistance. The pneumatic tire has a tread portion embedding belt layer therein, wherein the tread portion has plural rows of lag grooves extending from the tread end to a tire equatorial plane and a narrow groove connecting the end of two lag grooves clipping the tire equatorial plane, wherein the narrow groove will be closed when contacting the road surface, wherein said lag groove is composed of a first lag groove portion located on the outer side in the tire widthwise direction and a second lag groove portion located on the inner side in the tire widthwise direction, wherein the maximum depth of the second lag groove portion is larger than the maximum depth of the first lag groove portion, wherein the second lag groove portion, in a sectional view in the tire circumferential direction, is composed of a shallow groove portion and deep groove portion having a larger depth than the shallow groove portion notching a part of the shallow groove portion, wherein the length in the tire circumferential direction of the deep groove portion is smaller than the length in the tire circumferential direction of the shallow groove portion.
