The present invention provides for a truck tire tread (2) that has a shoulder area having a lateral sipe (23). The lateral sipe (23) has an average sipe line oriented at an average sipe angle greater than 20 degrees in absolute value oriented to the lateral direction (Y) running inboard to outboard. The lateral sipe (23) is also inclined such that a sipe inclination line miming from a sipe bottom point (31) to a sipe top point (32) in a reference plane perpendicular to the average sipe line is at a sipe inclination angle (35) from 10 to 50 degrees to a reference line oriented only in a thickness direction (Z) of the tread. The lateral sipe is inclined such that the sipe bottom point is configured to approach a contact patch before the sipe top point.
