A pneumatic tire includes a carcass layer, a belt layer that is disposed on the outer side in the tire radial direction of the carcass layer, and a tread rubber that is disposed on the outer side in the tire radial direction of the belt layer. The pneumatic tire also includes at least three circumferential main grooves extending in the tire circumferential direction, and a plurality of land portions that are defined by these circumferential main grooves. The belt layer includes an inner-side cross belt and outer-side cross belt having belt angles of not less than 51 and not more than 80 as absolute values with respect to the tire circumferential direction, the belt angles having mutually opposite signs, and a circumferential reinforcing layer having a belt angle that satisfies a range of 5 with respect to the tire circumferential direction.

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 5 with the tire circumferential direction; and a supplemental belt arranged outside the outer-side cross belt in the radial direction of the tire and forming a belt angle with the tire circumferential direction with an absolute value between 10 and 45 inclusive.

A pneumatic tire includes a carcass reinforced by a carcass ply extending from a first bead to a second bead and a belt structure including a first portion and a second portion. The belt structure is disposed radially outward of the carcass ply in a crown portion of the pneumatic tire. The first portion includes a belt with a belt width extending axially from a first shoulder portion of the crown portion to a second shoulder portion of the crown portion. The second portion includes a plurality of bands with band widths less than the belt width. One of the bands has a first group of cords oriented in a first direction relative to a centerline of the pneumatic tire and a second group of cords oriented in a second direction relative to the centerline of the pneumatic tire.

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.

The invention relates to a tire with a radial carcass reinforcement comprising a crown reinforcement, itself radially capped with a tread comprising at least two circumferentially continuous cutouts, the said tread being connected to two beads via two sidewalls. According to the invention, the crown reinforcement comprises at least one axially discontinuous layer consisting of at least two bands each formed of at least one multilayer laminate, the said laminate comprising at least one multiaxially stretched thermoplastic polymer film positioned between and in contact with two layers of rubber composition, and, in a meridian plane, the axial ends of each of the said bands being respectively axially on the outside of each of the axially outermost points of one same circumferentially continuous cutout.
