The invention relates to a tire with radial carcass reinforcement, made up of at least one layer of metal reinforcing elements, the said tire comprising a crown reinforcement, itself radially capped by a tread, the said tread being connected to two beads via two side walls, the said tire comprising a first layer of polymer compound radially between the carcass reinforcement and the radially innermost layer of reinforcing elements of the crown reinforcement. According to the invention, the said first layer of polymer compound constitutes a buffer zone designed to trap oxygen on the outside of the said first layer, the axial width of the said first layer being at least equal to 70% of the width of the radially innermost layer of reinforcing elements of the crown reinforcement.

Pneumatic tire for heavy duty vehicles having a crown portion comprising two working plies (114,116) and a breaker ply (120) radially outward of the carcass body ply wherein the breaker ply (120) comprises a plurality of breaker ply reinforcement elements (122) having a length L of no more than 155 mm, at an angle of 5<60.

A pneumatic vehicle tire of a radial type of construction is for heavy trucks and has a four-ply belt (3). Each belt ply (7, 8, 9, 10) contains steel cords as reinforcing elements which run parallel to one another in each belt ply. Not only are the angles (, ) that the steel cords in the second and third belt plies (8, 9) form with the circumferential direction (A-A) approximately equal, but also the angles (, ) that the steel cords in the first and fourth belt plies (7, 10) form with the circumferential direction (A-A) are likewise approximately equal.

A pneumatic tire comprises a carcass layer, a belt layer disposed on an outer side of the carcass layer in a tire radial direction, and a tread rubber disposed on the outer side of the belt layer in the tire radial direction. The belt layer formed by laminating an angle belt having a belt angle 45 and 70 in absolute values, a pair of cross belts, having belt angles of 10 and 45 in absolute values 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 a tire circumferential direction. A tread width TW and a cross-sectional width Wca of the carcass layer have a relationship such that 0.82TW/Wca0.92. A width Ws of the circumferential reinforcing layer and a cross-sectional width Wca of the carcass layer such that 0.60Ws/Wca0.70.

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 tire (10) comprises a crown (12) comprising a tread (20), a crown reinforcement (14), a carcass reinforcement (32), two side walls (22), two beads (24), each side wall (22) linking each bead (24) to the crown (12), the crown reinforcement (14) extending in the crown (12) in a circumferential direction (Z) of the tire (10). The textile wire-like hoop reinforcer element (48), the wire-like working reinforcer elements (46) and the wire-like carcass reinforcer elements (44) are arranged so as to define, in projection on the equatorial circumferential plane (E), a triangular mesh. The textile wire-like hoop reinforcer element comprises a core composed of a first strand comprising at least one monofilament, and a layer comprising at least two second strands, each second strand comprising at least one monofilament, each second strand of the layer being helically wound around the core.
