摘要： In a tyre for vehicle wheels, each of the two annular anchoring structures (4) comprises at least two annular reinforcing inserts (11, 11a, 11b, 11c), each of them being made up of at least one first elongated element (12) and at least two reinforcing elements (13, 13a, 13b) that are mutually spaced apart and each of which extends in a radial direction and comprises at least one second elongated element (15). An end portion (5) of at least one carcass ply (3, 3a, 3b) lies between two adjacent annular reinforcing inserts (11, 11a, 11b, 11c). The second elongated element (15) of at least one of the reinforcing elements (13, 13a, 13b) is of metal material and delimits an angle included between about 20° and about 70° relative to a radial direction passing through a radially internal point thereof.

摘要： Disclosed is a method and a system for determining a cornering angle of a tyre fitted on a vehicle during a running of said vehicle on a rolling surface. The method comprises the steps of: determining the lateral acceleration of a portion of the tyre tread spaced apart from the equatorial plane of said tyre; determining a rotation speed of said tyre; and determining said cornering angle from said lateral acceleration and said radial speed, by using characteristic curves of lateral acceleration amplitude versus predetermined values of cornering angle for at least one rotation speed.
