Method for controlling the rolling resistance of a running tyre and method for reducing the consumption of a running vehicle

A method for controlling a rolling resistance of a running tyre, the method comprising:

• manufacturing a tyre, wherein the tyre has an asymmetric internal structure configured to generate, between the tyre rotating in rectilinear running and ground, a structural lateral force;
• installing the tyre on a rim;
• mounting a wheel on a vehicle, wherein the wheel comprises said tyre and said rim, wherein the wheel is mounted with a camber angle configured to generate, between the tyre rotating in rectilinear running and the ground, a lateral camber force,
• wherein manufacturing the tyre comprises:
• obtaining an asymmetric external profile of the tyre that is asymmetric with respect to a middle line plane of the tyre and configured to generate, between the tyre rotating in rectilinear running and the ground, a lateral conicity force;
• and
• conferring, to the tyre, said asymmetric external profile,
• wherein one direction of the lateral conicity force is discordant with respect to one direction of the lateral camber force and wherein a modulus of the lateral conicity force is smaller than a modulus of the structural lateral force, so as to control a resulting lateral force comprising at least the lateral conicity force, the lateral camber force and the structural lateral force and to limit a rolling resistance of the tyre running on rectilinear trajectory.
