Abstract: A heavy truck tire tread (12) is provided that has a tread groove (14) that is not oriented completely in the longitudinal direction so as to extend in both the longitudinal direction and the lateral direction. The tread groove is at least partially defined by a leading edge wall and a trailing edge wall and a bottom surface. A stone ejector (24) engages either the leading edge wall or the trailing edge wall but not both the leading edge wall and the trailing edge wall. The stone ejector faces the non-engaged leading edge wall or the trailing edge wall. Also, the tread has an average void depth that does not go past a twenty percent line (36). The twenty percent line (36) is twenty percent of a full void depth (40) located from the outer surface of the tread, and the average void depth does not include decouple grooves and tread outboard from them.
