A motor vehicle tire, particularly for front wheels of motor vehicles, has a tread extending around an axis of rotation and includes a central annular portion which straddles an equatorial plane and two annular shoulder portions arranged on axially opposite sides of the central annular portion. The tread band has a void-to-rubber ratio of less than 10%, and the central annular portion has an axial extension less than 40% of the axial development of the tread band and includes at least a pair of first grooves extending substantially longitudinally on opposite sides of the equatorial plane. Each shoulder portion has an axial extension less than 35% of the axial development of the tread band and includes a plurality of second grooves extending substantially transversally forming an average angle with the equatorial plane of more than 90°. The central annular portion has a void-to-rubber ratio more than 0.15 and the first grooves include at least one first segment and at least one second segment which is inclined with respect to the first segment so as to form a concavity directed toward the equatorial plane. The first segment of each first groove is shorter than the second segment and precedes the second segment in the tire rolling direction.
