Metodo per controllare la resistenza al rotolamento di uno pneumatico in marcia e metodo per ridurre il consumo di un autoveicolo in marcia

A method for controlling the rolling resistance of a running tyre comprises: manufacturing a tyre (2), installing the tyre (2) on a rim, mounting a wheel on a vehicle (100). Manufacturing the tyre (2) comprises: obtaining an external profile of the tyre (2) asymmetric with respect to a middle line plane (Pt) of the tyre itself (2) and configured for generating, between the tyre (2) rotating in rectilinear running and the ground (S), a lateral conicity force (Co), conferring to the tyre (2) said asymmetric external profile (1 ). The asymmetric external profile (1 ) is obtained so as to control a resulting lateral force (F) exchanged between the ground (S) and the tyre (2) and to limit a rolling resistance of the tyre (2) running on rectilinear trajectory.
