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 1.10Gsh/Gcc.

A belt layer of a pneumatic tire includes an inner-side cross belt and an outer-side cross belt forming belt angles of mutually different signs with the tire circumferential direction with absolute values from 46 to 80, inclusive; a circumferential reinforcing layer arranged between the inner-side cross belt and the outer-side cross belt and forming a belt angle of within 5 with the tire circumferential direction; and a supplemental belt arranged inside of the inner-side cross belt in the radial direction of the tire and forming a belt angle with the tire circumferential direction with an absolute value from 10 to 45, inclusive.

A pneumatic tire includes a carcass, a tread portion and a belt having a first inclined belt ply, circumferential direction belt ply, second inclined belt ply, and third inclined belt ply. With respect to a tire circumferential direction, an angle of cords of the first inclined belt ply is from 45 to 60, an angle of a cord of the circumferential direction belt ply is 5 or less, an angle of cords of the second inclined belt ply is from 30 to 60, and an angle of cords of the third inclined belt ply exceeds 5 and is 30 or less. The width of the third inclined belt ply is 80% or more of a ground contact width, and the cords of the second inclined belt ply and the cords of the third inclined belt ply are inclined in opposite directions with respect to the tire circumferential direction.

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.

A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. A belt cord angle of a belt layer large angle belt is 45-70, opposite sign belt cord angles of cross belts are 10-45, and a reinforcing layer belt cord angle is within 5 of a circumferential direction. A reinforcing layer width Ws and a carcass cross-sectional width Wca satisfy 0.60Ws/Wca0.70. The reinforcing layer is radially outward of the cross belts which are radially outward of the large angle belt. A wider cross belt width Wb2 of the pair and Wca satisfy 0.79Wb2/Wca0.89. Wb2 and Wca satisfy 0.79Wb2/Wca0.89. Relationships 0.79Wb2/Wca0.84 and either 0.82TW/Wca0.92 or 0.79TW/SW0.89 are satisfied, where TW is a tread width and SW is a total tire width.

A pneumatic tire comprises a carcass layer, a belt layer radially outward of the carcass layer, and a tread rubber radially outward of the belt layer. The belt layer is formed by laminating a large angle belt having a belt-cord angle of 45-70, a pair of cross belts having belt cord angles of 10-45 with opposite sign belt cord angles, and a reinforcing layer having a belt cord angle satisfying 5 relative to a circumferential direction. A reinforcing layer width Ws and a carcass cross-sectional width Wca satisfy 0.60Ws/Wca0.70. A wider cross belt width Wb2 of the pair of cross belts and the carcass width Wca satisfy 0.79Wb2/Wca0.89. Relationships 0.79Wb2/Wca0.84 and either 0.82TW/Wca0.92 or 0.79TW/SW0.89 are satisfied, where TW is a tread width and SW is a total tire width.
