A reinforcement structure for a polymer ply includes a plurality of flat woven cords. Each flat woven cord has a width between 0.5 mm and 1.6 mm and a thickness between 0.2 mm and 0.8 mm thereby producing the reinforcement structure with an overall width between 25.0 mm and 26.0 mm. Each flat woven cord includes materials with melting points between 130 C. and 230 C.

A pneumatic tire is provided where a profile line in a tire meridian cross section of a center land portion defined by circumferential grooves and located on a tire equator is curved projecting outward in a tire radial direction. A carcass layer and a reinforcing layer include a recess portion curved projecting inward in the tire radial direction in a bottom region of the center land portion.

Moreover, the distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10Gsh/Gcc.

A pneumatic tire is provided with a carcass layer, a belt layer disposed on the outer side of the carcass layer in a radial direction of the tire, and tread rubber disposed on the outer side of the belt layer in the radial direction of the tire. The belt layer is formed by layering a pair of cross belts having belt angles with absolute values from 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. 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 end (p) to the inner circumferential surface of the tire have a relationship such that 1.10Gsh/Gcc.

A pneumatic tire comprises a tread portion provided with a band layer disposed radially inside a tread rubber provided with a first circumferential groove. Cords of the band layer are a hybrid cord formed by twisting together a first filament and a second filament having an elastic modulus lower than that of the first filament. In a region radially inside the first circumferential groove, a maximum thickness t1 of topping rubber on the radially outer side of the band cords is not more than 1.0 mm; a minimum distance d1 from the bottom of the first circumferential groove to the radially outer surface of the band layer is not more than 2.0 mm; and a distance d2 from a groove edge of the first circumferential groove to the radially outer surface of the band layer is not more than 15.0 mm.

In a pneumatic tire, a belt layer is formed by laminating a pair of cross belts having a belt angle, as an absolute value, of not less than 10 and not greater than 45 and having belt angles of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of 5 with respect to the tire circumferential direction. Moreover, the distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10Gsh/Gcc.
