Abstract
A pair of motor vehicle tires includes a front tire and a rear tire to be mounted respectively on a front wheel and a rear wheel of a two-wheeled vehicle, each tire of the pair having a tread band extending around an axis of rotation. The tread band of the front tire includes a central annular portion straddling an equatorial plane and two annular shoulder portions disposed on axially opposite sides of the central annular portion. The central annular portion includes at least a pair of first grooves extending substantially longitudinally on opposite sides of the equatorial plane in such a way as to form a concavity directed toward the equatorial plane. Each shoulder portion includes a plurality of second grooves isolated from the first grooves and extending substantially transversally so as to form an average inclination with the equatorial plane greater than 90°. The tread band of the rear tire includes instead a module which is replicated along a direction of circumferential development of the tire, the module including: at least one first pair of first grooves inclined in opposite directions with respect to the equatorial plane of the tire; each first groove of the first pair extending along a portion of the tread band between the equatorial plane and a respective shoulder and forming an average inclination less than 60° with the equatorial plane.
