Toyo announced a new 425/65R22.5 size for its M320 wide-base super single tire. Designed for tough on/off highway use in applications such as dump trucks, concrete mixers and refuse trucks, the M320 is the ideal solution for durability in construction and refuse hauling applications, the company says.
The M320 features large tread blocks with functional sipes and three wide zigzag grooves to improve traction both off the road and on the streets. It has a long life, the company says, due to an optimized casing profile that minimizes growth of the tread area while maintaining a more uniform and flatter tread radius during its service life. A cap base tread compound helps to prevent the concentration of stress in a single area, effectively reducing excessive heat build-up during operation. In addition to providing endurance in its design construction, the M320 can be retreaded to provide an economical work solution.
In addition to the new 425/65R22.5 size, the M320 is also 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 that require both traction and durability.
