Marangoni Tread North America Inc.'s (MTNA) new RD-LH tread is designed for drive axles in long-haul fleets.
The RD-LH has a closed-shoulder design that combines four large longitudinal grooves, three rows of cross-sculptured blocks, and longitudinal bridges, say MTNA officials.
The tread design has been in controlled testing throughout the United States and Canada since last October.
