The 8 mm tread depth is notably deeper compared to competitors, contributing to a longer lifespan and better traction on the road. The symmetrical tread pattern ensures even wear and consistent performance throughout the tire's life. The Scuff Guard ring provides extra protection for the tire sidewall, which is a valuable safety feature that many other tires lack. With a speed rating of M, these tires can safely operate at speeds up to 81 mph, which is sufficient for most trailer hauling needs.
