The invention includes tire treads, tires including the tire treads, and methods of forming a tire tread. The tire tread includes a length extending in a lengthwise direction, a width extending in a lateral direction, and a thickness extending in a depth-wise direction from an outer, ground-engaging side of the tread. The tire treads further include a sipe having a length, a height, a width, a thickness extending in a direction of the sipe width, and a cross-section taken along a plane extending in a direction of the sipe width and height, where the cross-section twists as the sipe thickness extends along the length of the sipe. Method of forming the tire tread includes molding into the tread a sipe and a void feature as recited herein.
