Toyo Tires’ M657 on-highway drive tire is SmartWay-certified by the U.S. Environmental Protection Agency and is suited for long-haul highway applications while helping to reduce greenhouse gas emissions. The tire features the company’s proprietary e-balance technology, which includes a stiffer belt package and bead construction for improved tire life, endurance, irregular wear resistance and fuel efficiency. The G-rated M657 is available in four sizes: 11R22.5, 295/75R22.5, 11R24.5 and 285/75R24.5.
Suited for single and twin drive-axle applications, the M657 features a 28/32-inch tread depth and Toyo’s multi-pitch groove design that enhances traction, even during the latter stages of original tread life. Large parallel-arranged center tread blocks help provide added stability and traction, while stone ejectors help protect the casing against stone drilling and the shoulder design helps resist irregular wear in long-haul applications.
High-elongation steel cord is used in the number-four belt to help protect the casing against impacts and cuts and to promote multiple retreads, while a special cap-and-base compound helps provide cooler running and longer casing life. Deep inside the M657 is a high-tensile rust and fatigue-resistant body ply cord to further facilitate multiple retreads for longer service life.
