Toyo Tires’ M677 is an EPA SmartWay-verified drive tire designed for improved efficiency, wear performance and traction in long-haul and regional applications.
The M677 features a four-groove design with wide, 28/32-inch deep tread, large tread blocks and a closed, high-rigidity shoulder rib to promote even wear. Better fuel efficiency comes from lowering the rolling resistance of the tire with a silica compound that reduces energy loss during operation without reducing tread life.
