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.

Tread pattern maximizes block size for high speed stability and superb cornering performance. High-density bead filler stiffens the sidewall to provide excellent steering response. Advanced, high-grip compound delivers superior mobility on both wet and dry surfaces and enhances tread wear. Tread block diversity disperses pitch variations to reduce noise for a quiet ride.
