Abstract
An asymmetric directional tread for a tire is disclosed. The tread has a plurality of ground engaging tread elements separated by grooves. The grooves include one wide circumferentially continuous groove having a width W, a plurality of circumferentially continuous grooves of an intermediate width between greater than 1/3 and 3/4W, at least one narrow circumferentially continuous groove having a width 1/10 to less than 1/3W located between a lateral edge and a circumferentially continuous groove of a greater width, and first and second sets of laterally extending grooves. The first set extends from the outboard lateral edges to an end location within 5% of the tread width from the equatorial plane. The second set extends from the inboard lateral edge to an end location within 5% of the tread width from the equatorial plane.
