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).
