18" Nitto NT420S Tires feature a non-directional, asymmetrical pattern that provides confident performance, 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 Nitto NT420S tire can be cross-rotated so it wears more evenly across the tire. This feature ensures a quieter, more comfortable ride and longer tread life. The result is a comfortable, ultra high performance radial tire.
