Abstract: Tyre containing cords made of crosslinked poly(vinyl alcohol) filaments. The casing and the belt of a tyre can be reinforced by employing a cord of filaments made of synthetic fibres of crosslinked, high-strength poly(vinyl alcohol), the cord having a wear resistance (S/d) satisfying the equation: S >/= 14.5 - 12 N gamma where N gamma is a torsion coefficient, when a test is performed on the cord withdrawn from the tyre, this cord containing at least 5 % by weight of a component which is insoluble in dimethyl sulphoxide at 120 DEG C. Application: increasing the durability of tyres for passenger vehicles.
