The M137 premium high-performance steer radial manufactured by Toyo Tires is now available in a 16-ply with increased load carrying capacity.  The M137 is designed for use on long haul, over-the-highway commercial applications.
 
This EPA SmartWay verified tire uses e-balance technology and stiffer construction to improve tire life and endurance as well as resist irregular wear and reduce fuel consumption.

The casing profile minimizes growth of the tread and maintains a more uniform and flatter tread radius to also improve the life of the tire. Smooth wear and extended tire life are also aided by a new tread design that creates even contact pressure distribution across the tread surface.
 
The two sizes offered in 16-ply are 295/75R22.5 and 285/75R24.5.
