The NT420S is an all-season truck and SUV radial that was specifically engineered to provide high performance and require less owner maintenance. 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 heel-toe wear that is typical of directional tires. Even wear ensures a quieter, more comfortable ride and longer tread life. The result is a stress-free, high performance radial.

The NT555R is a D.O.T.-compliant competition drag radial designed with maximum flexibility for the weekend drag racer. The NT555R combines a high grip compound and semi-racing construction to provide maximum traction at the starting line. The tire comes molded at 6/32 of an inch and features a unique reinforced belt package to provide improved traction and high-speed stability. The NT555R is the perfect performance radial for the street or strip.
