The tread includes first and second circumferential grooves which separate a central region from first and second shoulder regions. The tread includes a circumferential cut in the first shoulder region at a distance from the first circumferential groove; and a plurality of circumferentially repeated transverse groove modules. A first shoulder portion of each transverse groove module includes at least one main transverse groove which includes a first substantially rectilinear portion inclined by a first angle with respect to a radial plane, a second substantially rectilinear portion inclined by a second angle with respect to the radial plane and arranged between the circumferential cut and the first circumferential groove, and a first curve portion connecting the first and the second substantially rectilinear portions.

摘要： A pneumatic tire (10) has, in the surface of the tread (11), a central circumferential groove (12) located at the center of the contact patch width and extending circumferentially around the tire, a plurality of longitudinal grooves (13 (13a, 13b)) formed on the axially outside of the central circumferential groove (12), lug grooves (15), and blocks (16 (16a to 16c)) defined by the central circumferential groove (12), the longitudinal grooves (13), and the lug grooves (15). Each of the lug grooves (15) is formed such that its width in the shoulder region is greater than its width in the central region, and the sum of the groove area of the central circumferential groove (12) and the groove area of the longitudinal grooves (13) is smaller than the area of the lug grooves (15). As a result, the pneumatic tire (10) not only secures the wet braking performance and wear resistance performance on paved roads, but also improves the acceleration performance and braking performance and the steering stability performance on snowy roads.
