A tire (1) is disclosed with a tread portion having a plurality of sipes (15, 17, 19, 37, 39) being open at the radially outer surface of a tread block (9) or tread rib. The tire (1) has at least one sipe pattern comprising one or more straight sipes (15) extending in the radial direction of the tire (1) and two or more inclined sipes (17, 19, 37, 39). At least one straight sipe (15) is arranged between two inclined sipes (17, 19, 37, 39). The inclined sipes (17, 19, 37, 39) have a main sipe direction that is inclined by an angle (α) relative to the radial direction. One or more inclined sipes (17, 19, 37, 39) are positively inclined sipes (37) and one or more inclined sipes (17, 19, 37, 39) are negatively inclined sipes (39). In one aspect, one or more inclined sipes (17, 19, 37, 39) have a curved shape along the length of the sipe (17, 19, 37, 39) or comprise at least one fold dividing the inclined sipe (17, 19, 37, 39) in two or more sub-portions (21, 23, 29, 31) being successive along the length of the sipe (17, 19, 37, 39). In another aspect, at least two inclined sipes (17, 19, 37, 39) have different depth. In yet another aspect, at least two sipes (15, 17, 19, 37, 39) of the sipe pattern have a depth of at least 6 mm and one or more inclined sipes (17, 19, 37, 39) have a curved shape along the length of the sipe (17, 19, 37, 39) or comprise at least one fold dividing the inclined sipe (17, 19, 37, 39) in two or more sub-portions being successive along the length of the sipe (17, 19, 37, 39), and the one or more straight sipes (15) and the two or more inclined sipes (17, 19, 37, 39) have directions divergent from each other from their open ends to their innermost ends.
