Pneumatic tire

A pneumatic tire comprising:

• a carcass layer;
• a belt layer disposed on an outer side in a radial direction of the tire of the carcass layer;
• a tread rubber disposed on an outer side in the radial direction of the tire of the belt layer;
• at least three circumferential main grooves extending in a circumferential direction of the tire;
• and a plurality of land portions defined by the circumferential main grooves;
• the belt layer being formed by layering a pair of cross belts having belt angles with absolute values of 10° to 45° inclusive and opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to the circumferential direction of the tire, the circumferential reinforcing layer being configured by belt cords formed from steel;
• a distance Gcc from a tread profile to an inner circumferential surface of the tire along a tire equatorial plane and a distance Gsh from a tread edge to an inner circumferential surface of the tire having a relationship such that 1.25≤Gsh/Gcc;
• defining an intersection between a vertical line drawn from the tread edge to the inner circumferential surface of the tire and a wider cross belt of the pair of cross belts as point Q1 and a base of a vertical line drawn from an outer end of the circumferential reinforcing layer with respect to a widthwise direction of the tire to the wider cross belt as point Q2, a distance Gs from point Q1 to the tread profile and a distance Ge from point Q2 to the tread profile having a relationship such that 1.00≤Gs/Ge;
• defining point Q3 as an intersection between a groove centerline of a circumferential main groove nearest the tire equatorial plane and a belt ply out of steel cord belt plies constituting the belt layer that is located furthest outward in the radial direction of the tire as seen in a longitudinal cross-sectional view of the tire, a groove depth Dc of the circumferential main groove nearest the tire equatorial plane and a distance Tc from the point Q3 to the tread profile have a relationship such that 1.30≤Tc/Dc≤1.55;
• and
• defining point Q4 as an intersection between a vertical line drawn from an end portion of the circumferential reinforcing layer to the tread profile and a belt ply out of belt plies made of steel cord constituting the belt layer on an outermost side in the radial direction of the tire when viewed as a cross-section from a longitudinal direction of the tire, a groove depth De of the circumferential main groove on an outermost side in the widthwise direction of the tire and a distance Te from point Q4 to the tread profile have a relationship such that 1.35≤Te/De≤1.60;
• wherein the pneumatic tire is a heavy duty tire with an aspect ratio of 70% or less.
