The M647 is designed using Toyo's e-balance technology which minimizes the growth of the tread profile during operation. This helps to maintain a more uniform and flatter tread radius during the entire life of the casing, resulting in long wear. The casing profile is also enhanced with the combination of e-balance profile retention technology and a high stiffness bead. Sheer strain is reduced at the belt edge area in the tread and in the bead.
Irregular wear is reduced by incorporating high rigidity in the shoulder of the tire, improving the durability of the M647. Traction is also maintained over the life of the tread because of deep slits engineered into the design that are equal to the main groove depth. The initial size offering of the Toyo M647 premium drive radial is a 295/75R22.5 in a 14-ply, load range G.
