摘要： In a cross-sectional view of a pneumatic tire in the tire meridian direction, land sections, which are located on the inner side of left and right outermost circumferential main grooves in the tire width direction, have a first profile which protrudes outward in the tire radial direction. In addition, shoulder land sections, which are located on the outer side of the right and left outermost circumferential main grooves in the tire width direction, have a second profile which protrudes inward in the tire radial direction within a ground contact surface. In addition, the distance between a line extending from the first profile in the ground contact surface of the shoulder land section and the second profile in the tire radial direction increases toward the outer side in the tire width direction.

摘要： 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.

摘要： This pneumatic tire (1) has a first profile (PL1) wherein land sections (3) located further inside in the tire width direction than right and left outermost circumferential main grooves (2) protrudes outward in the tire radius direction. In addition, the pneumatic tire has a second profile (PL2) wherein shoulder land sections (3) protrudes inward in the tire radius direction within a ground contact surface. The distance d in the tire radial direction from a line extending from the first profile (PL1) to the second profile (PL2) within the ground contact surface increases toward the outer side in the tire width direction. In addition, the distance (Gcc) from a tread profile (first profile (PL1)) within a tire equatorial plane (CL) to a tire inner circumferential surface and the distance (Gsh) from a tread end (P) to the tire inner circumferential surface have the relationship of 1.10≤Gsh/Gcc.
