TRUCK TIRE TREAD WITH ANGLED RIBS HAVING STONE EJECTORS

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. 提供一种重型卡车轮胎胎面(12)，其具有胎面花纹沟(14)，该胎面花纹沟不完全在纵向方向上定向以在纵向方向和横向方向上均延伸。所述胎面花纹沟至少部分地由前缘壁和后缘壁以及底表面限定。石块弹出部(24)与前缘壁或后缘壁接合，但不与前缘壁和后缘壁两者接合。石块弹出部面向所述未接合的前缘壁或所述后缘壁。而且，胎面的平均空隙深度不超
