In the field of tire production, the invention relates to a tire for a vehicle, the tire (300) including a summit having a tread (312) with asymmetric tread elements for contacting the ground, and the tire (300) being provided with a sealed inner liner that defines a tire cavity when the tire is mounted on a mounting rim, wherein a first noise damper (330) is circumferentially affixed to an inner surface (300a) facing the cavity of the tire (300), the first noise damper (330) being positioned in the cavity of the tire (300) toward an outer side of the tire (300) and being off-center with respect to a median plane (C.sub.300) of the tire (300).

In a pneumatic tire, a rubber surface layer portion comprises a first rubber portion formed from a first rubber, and a second rubber portion formed from a second rubber having a rubber hardness greater than a rubber hardness of the first rubber, the first rubber portion is arranged at a first side in a tire width direction, the second rubber portion is arranged at a second side in the tire width direction, an interface between the first rubber portion and the second rubber portion is arranged between a pair of main grooves that are arranged in outwardmost fashion in the tire width direction, and an average tire outside diameter toward the second side in the tire width direction from a tire equatorial plane is greater than an average tire outside diameter toward the first side in the tire width direction from the tire equatorial plane.

A circumferential direction protrusion is provided extending longitudinally mainly along a tire circumferential direction on a side outward in a tire radial direction from a maximum tire width position on at least a first tire side portion of a tire.

This tire is provided with reinforcing cord layers that reinforce a bead part. The reinforcing cord layers are such that at the bead part at the inner side of vehicle mounting, the number of layers of the reinforcing cord layers with respect to a bead filler is greater at the inner side in the direction of tire width compared to the outer side in the direction of tire width with respect to the bead filler, and at the bead part at the outer side of vehicle mounting, the number of layers of the reinforcing cord layers with respect to the bead filler is greater at the outer side in the direction of tire width compared to the inner side in the direction of tire width with respect to the bead filler.

A pneumatic tire that can achieve sufficient quietness via a band-shaped sound absorbing member attached to a tire inner surface and prevent a reduction in high-speed durability caused by the accumulation of heat in the band-shaped sound absorbing member during high-speed travel. The pneumatic tire includes a band-shaped sound absorbing member (10) bonded along a tire circumferential direction to the tire inner surface in a tread portion (1); at least one full cover layer (8f) covering the entire width of belt layers (7) on the outer circumferential side of the belt layers (7); and a center cover layer (8c) disposed on the outer circumferential side of the full cover layer (8f), the center cover layer (8c) locally covering the tire lateral direction center region of the belt layers (7); a width SW of the band-shaped sound absorbing member (10) and a width BW of the belt layers (7) satisfying a relationship SW/BW=0.3 to 0.8, and a width CW of the center cover layer (8c) and the width SW of the band-shaped sound absorbing member (10) satisfying the relationship CW/SW=0.05 to 0.35.

Method for controlling the symmetry of the footprint area of a tyre miming on a straight trajectory with camber angle different from zero, wherein the method comprises the steps: reducing the contact pressure of the tyre (2) on the footprint area at an inner shoulder (in case of negative camber) or at an outer shoulder (in case of positive camber); disposing any medium line (Im) of the tread band (9) placed in correspondence with the footprint area substantially parallel to the ground; the invention also defines a tyre and a wheel for motor-vehicles, wherein the medium line (Im) of the tread hand (9) and the rotation axis (X-X) of the tyre (2) form an angle (a) substantially equal in absolute value to the camber angle (?); the invention also encompasses a process for manufacturing such tyres, wherein a green tyre with symmetric outer profile is deformed during the vulcanising and moulding step until a predetermined angle (a) different from zero is formed between any medium line (Im) of the tread band (9) and the rotation axis (X-X) of the vulcanised tyre (2).

A green tyre has a symmetric profile in radial section having a radially outer tread band, two radially inner beads and two sidewalls each extended from one edge of the tread band to one of the beads. During a moulding and vulcanisation treatment of the green tyre, a movement is imposed to the tread band with respect to the beads along a direction parallel to a rotation axis of the tyre, to obtain a moulded and vulcanised tyre having an asymmetric profile in radial section. A mould for vulcanizing tyres for vehicle wheels is also described, having a tread wall axially asymmetric with respect to a middle line plane of the mould.
