A heavy truck tire tread with a rib (18) located between first (14) and second (16) tread grooves. A shoulder block (30) is adjacent the rib and at a shoulder edge of the tread, and a decouple groove (32) is present that decouples the shoulder block from the rib. The decouple groove is spaced from and free from engagement with the shoulder edge, and extends at least twice as long in the longitudinal direction than in the lateral direction. The width of the decouple groove is less than widths of the first and second tread grooves. The tread has an average void depth that does not go past a twenty percent line, where the twenty percent line is twenty percent of a full void depth located from an outer surface of the tread, and where the average void depth does not include decouple grooves and tread outboard from the decouple grooves.
