The Nitto NT555RII is a DOT-compliant competition drag radial tire engineered specifically for drag racing applications while maintaining limited street driving capability. This tire represents the evolution of Nitto's drag radial development, fusing the best qualities of the previous NT555R and NT05R models with a tread pattern matched to the NT555 G2 ultra-high performance street tire for improved aesthetics and versatility. The NT555RII features race compound formulations designed to deliver maximum traction at the starting line, with modified sidewall construction engineered to improve launch characteristics and 60-foot times compared to earlier generations. The tire incorporates large twin center ribs that provide a continuous contact patch for enhanced dry traction during acceleration runs, while maintaining sufficient tread pattern to meet DOT certification requirements.
The Nitto NT555RII delivers exceptional drag strip performance with users consistently reporting improved 60-foot times and dead hook launches that effectively transfer high horsepower to the ground, with testing showing reliable traction for vehicles producing 600+ wheel horsepower. The optimized tread pattern and robust sidewall construction ensure superior control and driving precision during drag racing while maintaining reasonable street driving characteristics for transportation to and from racing facilities. Independent reviews note the tire feels stable even during wet weather compared to typical drag radials, though sensible driving is essential in rain and the tire should never be driven on extremely wet roads with standing water, in near-freezing temperatures, through snow, or on ice. Available in sizes ranging from 15 to 20-inch rim diameters, the NT555RII serves drag racers seeking maximum straight-line performance while accepting trade-offs including relatively high noise levels, accelerated tread wear (some users report near-bald conditions after 4,000 miles), premium pricing compared to competitors, and no manufacturer treadwear warranty. The NT555RII represents Nitto's flagship drag radial offering for serious competitors prioritizing launch traction and acceleration performance above all other tire characteristics.
