摘要： A method of calculating forces acting on the footprint area of a tyre, said tyre (1) being mounted on a wheel (2) in turn mounted on a hub (3) for engagement with a vehicle, said tyre (1) being moved along a longitudinal direction substantially parallel to the ground (4), said method comprising the following steps: detecting a first angular position (α) of said footprint area (5); detecting a second angular position (β) of a reference point (P) substantially integral with said hub (3); comparing said first and second angular positions (αr β) with each other to determine a phase displacement (δφ) between said reference point (P) and footprint area (5); determining a parameter (k) representing an angular velocity (ω) of said wheel (2); calculating at least one longitudinal force (Fx) in said footprint area (5) as a function of at least said phase displacement (δφ) and said parameter (k). Also described is an apparatus for calculating said forces.

摘要： A pneumatic tyre (10) having a reinforced bead structure (15), wherein at least one flipper (17) is provided to at least parcially envolope the respective annular reinforing element (14) and bead fillter (16). The flipper comprises a plurality of mutually substantially parallel elongated reinforcing elements which comprises at least one preformed threadlike metallic element having a diameter in the range of from 0.25 mm. The resulting tyre has improved durability,especially at high speed and/or extreme driving conditions, combined with exellemt handling and ride comfort characteristics.
