<p>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.</p> |
