Nitto NT555 G2 Summer Ultra High Performance Tire

The Nitto NT555 G2 is the next-generation ultra high performance summer tire engineered for the serious performance driver. Built as a measurable step forward from the original NT555, the G2 delivers meaningful improvements in dry traction, wet braking, and overall handling — making it a top choice for sports cars, muscle cars, performance coupes, and high-powered sedans.

Advanced Directional Tread Design:

• Twin center ribs maximize the contact patch for superior dry traction and straight-line stability at speed
• Large tapered tread blocks increase grip capability and deliver enhanced cornering stability under hard driving loads
• Reinforced shoulder tread blocks improve both wet and dry cornering grip for confident, aggressive driving maneuvers
• Directional tread pattern provides an aggressive, purposeful appearance that complements high-performance builds

Wet Weather Capability:

• Four wide circumferential grooves — combining center and shoulder channels — efficiently evacuate water from the contact patch to reduce hydroplaning risk
• Lateral shoulder grooves work in tandem with the circumferential channels to optimize wet handling and braking response
• High-silica tread compound maintains consistent grip in both wet and dry warm-weather conditions

Proprietary High-Stiffness Silica Compound:

• A specialized bonding agent increases the interaction between all compound elements, reinforcing chemical bonds for higher compound rigidity during cornering
• Results in better handling in both wet and dry conditions across the tire's full service life
• Extra-rigid internal construction — a two-ply polyester casing paired with two wide steel belts reinforced by nylon cap plies — provides structural stability during hard cornering and sustained high-speed driving
• UTQG ratings of Traction AA / Temperature A reflect the compound's top-tier performance credentials

Summer-Optimized Performance:

• Engineered specifically for warm-weather driving — performs at its best when ambient temperatures are consistently above 40–45°F
• Not intended for winter, near-freezing, or below-freezing conditions — like all ultra high performance summer tires, the NT555 G2 should be removed and properly stored when cold weather arrives
• Tires exposed to temperatures of 20°F (-7°C) or lower must be allowed to gradually return to at least 40°F before being flexed, mounted, or driven on

Backed by Nitto's motorsport heritage and a manufacturer's limited warranty, the NT555 G2 combines track-inspired engineering with everyday street drivability. Available in a wide range of sizes to suit both staggered and square fitment setups across sports cars, muscle cars, and performance sedans.
