The tire tread presents a thickness T20 and a sipe (30) having a length and a depth d3o extending into the tread thickness in a direction away from an outer, ground-engaging side of the tread. The sipe articulates between an open configuration and a closed configuration as the tire rotates during tire operation. The sipe has a variable-width W30 extending transverse to the sipe length and transverse to the depth in the open configuration, the variable-width being defined by a pair of opposing sipe sides (34). The variable-width decreases as the depth increases into the tread thickness in a direction away from the outer, ground-engaging side. The opposing sipe sides substantially engage each other at substantially the same time in the closed configuration.
