PAIR OF MOTOR VEHICLE TYRES

摘要

Pair of motor vehicle tyres (1), comprising a front tyre and a rear tyre to be mounted respectively on a front wheel and a rear wheel of a two-wheeled vehicle, each tyre of the pair having a tread band (8) extending around an axis of rotation (Z). The tread band (8) of the front tyre comprises a central annular portion (A) straddling an equatorial plane (X-X) and two annular shoulder portions (B) disposed on axially opposite sides of the central annular portion (A). The central annular portion (A) comprises at least a pair of first grooves (120) extending substantially longitudinally on opposite sides of the equatorial plane (X-X) in such a way as to form a concavity directed towards the equatorial plane (X-X). Each shoulder portion (B) comprises a plurality of second grooves (121) isolated from the first grooves (120) and extending substantially transversally so as to form an average inclination with the equatorial plane (X-X) greater than 90°. The tread band (8) of the rear tyre comprises instead a module (14) which is replicated along a direction of circumferential development of the tyre, said module (14) comprising: at least one first pair of first grooves (12; 13) inclined in opposite directions with respect to the equatorial plane (X-X) of the tyre; each first groove (12; 13) of the first pair extending along a portion of the tread band comprised between the equatorial plane (X- X) and a respective shoulder and forming an average inclination less than 60° with the equatorial plane (X- X) °
