Its center island tread elements are designed for great traction in wet or dry maneuvers. It features a radical shoulder ribs that act like traction bars and stabilizes the tread for longer life in commercial service. Its all steel casing construction resists punctures, increases vehicle stability and contributes to more retread cycles. Its curbing ribs help shield the casing from sidewall damage and the multi-phase shift tread pattern minimizes tire noise. The reinforcing bridges of rubber tie together the tread package for vehicle stability and resistance to irregular wear. Its computer designed tread pattern and application specific compounds deliver vehicle stability, long mileage and excellent traction.
