In another aspect, a sipe comprises along its elongated sipe portion a) a radially outer sipe portion extending with an undulated shape; b) a radially inner sipe portion, extending with an essentially linear shape; and c) a transition portion, provided radially between the radially outer sipe portion and the radially inner sipe portion, and having a shape radially transitioning from the undulated shape of the radially outer sipe portion to the linear shape of the radially inner sipe portion.",
