By utilizing a racing concept design, Nitto Tire's engineers developed the NT-555 "Extreme ZR". With a specially formulated compound and one of the biggest contact patches available, the NT-555 provides superior traction, reliable handling, and delivers total vehicle control. The three-circumferential grooves channel water efficiently, while the lateral grooves break up the water wedge. This combination of grooves and channels reduces the chance of hydroplaning.
 

The Nitto NT-555R Extreme Drag Radial Tire is an exciting addition to the specialty performance radial tire segment of the Nitto Tire Product Line. With the NT-555R Nitto engineers succeeded in designing a DOT approved, drag racing radial tire. Nitto Tire demanded a tire that would outperform all drag racing radial tires, provide impressive control and handling, and still deliver up to 15,000 miles of tread life of normal street-driving use.
