Luxury Truck and SUV. The NT420S was specifically engineered to provide confident performance in rain or shine. The outer shoulder has large, continuous blocks to improve dry traction, while the inner shoulder channels away water for wet performance. The NT420S has a non-directional tread pattern that can be rotated front to back and side-to-side. This freedom of rotation can provide even wear across the tread and reduce the irregular wear that is commonly associated with directional tires. Even wear ensures a quieter, more comfortable ride and longer tread life. The result is a stress-free, high performance radial.
