The present invention relates to a tire which has improved lateral grip performance on snow-covered ground surfaces without adversely affecting grip performance on wet ground surfaces and dry ground surfaces. The tread is obtained by repeating a tread pattern (MA, MB) on one rotating ring of the wheel at a pitch (PA, PB), where Palt; and PB. Each first side (ZB) of the tread pattern comprises at least one longitudinal sipe (50), the path of which on the rolling surface (15) is a median plane (53) forming an angle beta with the circumferential direction in the range of 0 DEG to 20 DEG. The same median plane (53) also forms an angle alpha in the range of 3 DEG to 55 DEG with a direction (Npsup) perpendicular to the rolling surface (15), and the sum of the lengths of the longitudinal sipes (50) projected onto all the first sides (ZB) in the circumferential direction is between 0.5 and 5 times the circumference of the tire measured in the equatorial plane.
