The symmetric ribbed tread design features a flat footprint that ensures constant road contact and evenly distributes load and driving pressure, resulting in reduced rolling resistance and improved fuel economy. Dense siping shortens braking distance, while the circumferential grooves effectively disperse water and slush to resist hydroplaning.

The reinforced steel belt construction allows the tire to maintain its optimal shape while under load and driving pressure, enabling it to carry and withstand heavy loads for extended periods of time. This all season tire is tubeless and designed to provide reliable traction and stability throughout the year in commercial highway applications.
