摘要： 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 (β); 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).

摘要： A method for controlling the symmetry of the footprint area of a tyre running on a straight trajectory with camber angle different from zero, includes the steps: reducing the contact pressure of the tyre on the footprint area at an inner shoulder (in case of negative camber) or at an outer shoulder (in case of positive camber); and disposing any medium line of the tread band placed in correspondence with the footprint area substantially parallel to the ground. A tyre and a wheel for motor-vehicles, wherein the medium line of the tread band and the rotation axis of the tyre form an angle substantially equal in absolute value to the camber angle. 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 different from zero is formed between any medium line of the tread band and the rotation axis of the vulcanised tyre.

摘要： A wheel for vehicles includes: a rim and a tire mounted on the rim and inflated to an operating pressure; axial end portions of a tread band of the tire radially spaced apart the same distance from a rotation axis of the wheel and a median circumferential line of the tread band axially shifted by a predetermined distance relative to a mid-line plane of the wheel; the wheel mounted on a car with a camber angle substantially zero and with the median circumferential line shifted toward the outside of the car relative to the mid-line plane.

摘要： 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.
