A radial ply pneumatic tire for trucks or trailers has a tread with at least three circumferential grooves extending circumferentially to divide the tread into at least four parts and lateral grooves extending across the at least four parts of the tread to form at least four rows and of circumferentially separated blocks The circumferential grooves have average groove widths of W for a depth between the radially outer surface of the adjacent blocks and a groove depth that is less than 60% of the non-skid depth D, the circumferential grooves having a second average groove width W at the groove depth less than 60% of the non-skid depth D, the second average groove width W being less than 50% of W . The lateral grooves in each shoulder row have a first average groove width W and a groove depth that is less than 60% of the non-skid depth D. The lateral grooves in the central rows and have a first average length L for a depth between a radially outer surface of the adjacent blocks and a groove depth that is less than 60% of the non-skid depth D, the lateral grooves in the central rows having a second average length L at the groove depth that is less than 60% of the non-skid depth D, the second average length L being greater than the first average length L . The tie when new, provides a tread for the drive axle position and when less than 60% worn, the tread pattern changes to one ideally suited for the trailer wheel position.
