Toyo says it designed a new 425/65R22.5 size for its M320 wide-base super single tire for tough on-/off-highway use in applications such as dump trucks, concrete mixers and refuse trucks. The M320 features large tread blocks with functional sipes and three wide zigzag grooves designed to improve traction both off the road and on the streets.

The tire has a long life due to an optimized casing profile designed to minimize growth of the tread area while maintaining a more uniform and flatter tread radius during its service life, according to the company. A cap base tread compound helps to prevent the concentration of stress in a single area, effectively reducing excessive heat buildup during operation, Toyo says.

In addition to the new 425/65R22.5 size, the retreadable M320 also is available as a wide-base super single in a 385/65R22.5 size. Conventional sizes of the tire include an 11R22.5, 12R22.5, 315/80R22.5 and an 11R24.5 for a variety of fitments which require both traction and durability.
