Onyx All Steel NTL323. FEATURES AND BENEFITS: All season traction; Heavy-duty controllability; Longer lasting tread life; . OVERVIEW: The Onyx All Steel NTL323 is a highway terrain, all season tire manufactured for trailers. This tire is NOT MEANT TO BE MOUNTED ON LIGHT TRUCKS, as its construction will not support the weight and performing style of such vehicles. It can ONLY BE MOUNTED ON TRAILERS.All weather traction is enhanced with this tire model. It combines the all season compound and the symmetric ribbed tread design with the rib-edge sipes. The stronger compound enables the tire to keep the rubber flexibility in versatile temperatures, optimizing the summer and winter weather performance. The rib edge sipe and notch placement increase the grip on the road surface with extra biting edges, upgrading the surface traction. The circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, resulting in a safer wet weather performance.The ribbed tread design and the stronger compound enhance the heavy-duty controllability. The flat footprint ensures the tire's surface contact at all times, upgrading the steering responsiveness and driving stability. In this manner, the tire improves the steering response time and precision to the towing vehicle's instructions, while it secures structural stability. On the other hand, the steel belt structure keeps the ideal tire shape under the load and driving pressure. As the tire does not deform under the load pressure, it is able to significantly upgrade the load capacity. This boosts the overall load durability, while optimizing the towing vehicle's power over the trailer.The All Steel NTL323 boosts the length of the tread life. The excellent stability of the ribbed tread design and the stronger rubber materials of the compound increase the usability. The stable footprint avoids irregular wear as it manages to equally circulate the forces of acceleration, cornering, and braking across the tread area. The wear-resistant compound elements allow the tire to decrease treadwear rate, slowing the overall wear down. This combination significantly upgrades the service and tread life. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
