Toyo has a new 425/65R22.5 size for its M320 wide-base single tire for dump trucks, concrete mixers and other on/off-road applications. The M320 features large tread blocks with functional sipes and three wide zigzag grooves to improve traction on and off pavement. It claims a long life due to an optimized casing profile, which minimizes growth of the tread area while maintaining a more uniform and flatter tread radius.  A cap base tread compound helps to prevent the concentration of stress in a single area, reducing excessive heat build-up during operation. The M320’s casing can be retreaded to provide additional service. The M320 is also available in a 385/65R22.5 size, and in several conventional sizes.
