Performance & Key Benefits
What Makes UN-ALL STEEL Ready for the Road
Strength You Can Tow With
01. Durable All-Steel Construction
The all-steel construction provides a strong and durable foundation for trailer service. It helps the tire maintain its shape and consistent performance under the pressures of towing, supporting dependable performance throughout everyday highway use.
Confident Grip Through Changing Weather
02. All-Season Traction for Highway Travel
The all-season compound and ribbed tread design work together to provide dependable traction on dry, wet, and cooler roads. The tread design is built to maintain useful grip as road and weather conditions change.
Stay Steady Behind the Tow Vehicle
03. A Flat Footprint for Stable Tracking
The flat footprint and ribbed tread increase the tire's contact with the road surface, helping improve steering response and driving stability. This supports more predictable trailer tracking during highway towing.
UN-ALL STEEL
Ready When the Road Turns Wet
04. Grooves Help Clear Water & Slush
The circumferential groove pattern helps disperse water and slush from the footprint. This supports wet-weather traction and helps resist hydroplaning when towing on wet highways.
Made for More Consistent Wear
05. Durable Tread Performance for the Long Haul
The ribbed tread design and durable compound work together to promote more even pressure distribution across the tread. This helps reduce irregular and premature wear while supporting longer-lasting tread performance.
Backed for the Long Haul
06. Peace of Mind, Mile After Mile
Enjoy peace of mind with a 3-year road hazard warranty covering bulges, air leaks and blowouts before 4/32" of treadwear, plus a 5-Year Manufacturer Warranty.
