A pneumatic tire comprises a carcass layer, a belt layer disposed on the outer side in the tire radial direction of the carcass layer, and tread rubber disposed on the outer side in the tire radial direction of the belt layer. The belt layer is formed by laminating a pair of cross belts having belt angles with an absolute value from 10 to 45 both inclusive and mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of 5 relative to the tire circumferential direction. 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. The groove depth (Dsh) and under-groove gauge (UDsh) of the outermost circumferential main groove have a relationship satisfying 0.20UDsh/Dsh.

The tire includes: a carcass toroidally extending between a pair of bead portions; a spiral cord layer arranged on an outer side in a tire radial direction of a crown portion of the carcass and in which an upper layer and a lower layer are formed by spirally winding a reinforcing cord; and an auxiliary belt layer arranged on the outer side in the tire radial direction of the spiral cord layer. At least at ends in a tire width direction of a region where the spiral cord layer and the auxiliary belt layer are laminated, a 100% modulus of at least a rubber other than a coating rubber of the auxiliary belt layer among rubbers interposed between the spiral cord layer and the auxiliary belt layer is lower than a 100% modulus of the coating rubber of the auxiliary belt layer.

A radial tire with a lightened belt structure (10) comprises a multilayer composite laminate (10a, 10b, 10c) of specific construction, with a first layer (10a) of rubber (C1) reinforced with preferably weakly heat-shrinkable circumferential textile multifilament fibres (110) twisted individually on themselves with a torsion T greater than 100 turns per meter, for example, made of nylon or of polyester, this first layer radially (in the direction Z) surmounting two other layers (10b, 10c) of rubber (C2, C3, respectively) reinforced with monofilaments (120, 130) of high tensile steel. The first reinforcers have an envelope diameter between 0.30 mm and 0.60 mm and a density, measured in the axial direction Y, between 90 and 150 threads/dm, and the second and third reinforcers each have a diameter between 0.20 mm and 0.50 mm and a density, measured in the axial direction Y, between 100 and 180 threads/dm.

A pneumatic tire includes a tire case, a tread and a single-layer belt. The tire case includes a carcass that extends from one bead portion to another bead portion. An outer side portion of the carcass is covered with a side rubber layer formed of a first rubber material. The tread is disposed at the tire radial direction outer side of the tire case and is formed of a second rubber material. The belt is disposed between the tire case and the tread. The belt includes a resin-covered cord that is wound in a spiral shape. The resin-covered includes a cord covered with a resin with a greater tensile modulus of elasticity than the first rubber material and the second rubber material. The resin at one winding and another winding of the resin-covered cord, which are adjacent in the tire width direction, are welded together.
