The Nitto NT555 G2 represents the next generation evolution of Nitto's ultra-high performance summer tire line, engineered for drivers of muscle cars, sports cars, performance coupes, and sedans seeking optimal dry and wet traction with improved capabilities over the original NT555. This tire incorporates advanced design elements including twin center ribs for enhanced dry traction and straight-line stability, large tapered blocks providing increased grip capabilities and superior cornering stability, and circumferential center and shoulder grooves that efficiently evacuate water to enhance wet handling characteristics. The silica-enriched tread compound delivers sticky formulation with exceptional road adhesion, while extra stiffness provides confidence and responsive feedback during aggressive cornering. The NT555 G2 carries impressive UTQG ratings of 320 AA A, reflecting its balanced approach between performance capabilities and reasonable durability for an ultra-high performance summer tire.
The Nitto NT555 G2 features tire sizes with 275mm and greater section widths incorporating larger tread blocks compared to narrower sizes, specifically optimizing traction for rear applications on vehicles with staggered fitments and high horsepower. Independent testing demonstrates the tire achieves approximately 0.9 lateral g-forces with peak cornering forces reaching 1.2 g's in compression zones, performance levels on par with premium competitors including Sumitomo and OEM Pirelli alternatives. User reviews consistently praise excellent ride quality, minimal road noise, strong wet weather confidence, and grippy street characteristics with zero tire spin during full-throttle acceleration testing. The NT555 G2 is available with W speed ratings appropriate for performance applications on vehicles including Acura Integra, BMW M3, Cadillac CTS, Chevrolet Camaro, Dodge Challenger, Ford Mustang, Nissan 350Z, and Subaru Impreza. The tire delivers a compelling cost-to-performance ratio making it accessible for budget-minded but quality-oriented enthusiasts seeking high performance levels without premium tire pricing. Like all summer tires, the NT555 G2 is designed exclusively for warm weather operation and should never be driven in near-freezing temperatures, through snow, or on ice.
