The present invention includes an improved tire tread having recessed lateral grooves, and a tire having the same. Particular embodiments of the tread include a tread thickness bounded depthwise by a top side configured to engage a ground surface during tire operation and a bottom side configured to attach to a tire carcass, the thickness extending laterally between a first side edge and a second side edge and longitudinally in a lengthwise direction of the tread. The tread further includes a longitudinal groove in fluid communication with the top side or the bottom side of the tread thickness and a lateral groove in fluid communication with the bottom side of the tread thickness extending from the first side edge intersecting the longitudinal groove forming a vent passageway extending from the longitudinal groove and to the first side edge. The invention includes methods of forming such treads and molds there for.
