Date Jul. 31, 1997An on/off road radial pneumatic light truck or automobile tire has a tread with at least one wide groove having an average width of at least 7% of the tread width. At least two axially adjacent rows of traction elements are separated by the wide groove. The tread has a plurality of protrusions extending from traction elements into the wide groove. The protrusions are sloped radially inwardly at an angle in the range of 20 DEG to 60 DEG relative to the radial direction from the outer surface of the traction element toward the tread base and crossing axially more than halfway across the wide groove width toward an intersection of a lateral groove and the wide groove. The protrusions extending from traction elements on one side of the wide groove are circumferentially offset and at least partially axially aligned with protrusions extending from traction elements on the opposite side of the wide groove.
