Nitto NT555R2 Review: Maximizing Your Car’s Performance On The Track Overview
The Nitto NT555R2 is a street-legal drag radial tire, but its capabilities extend far beyond just straight-line launches. It’s engineered with a specific purpose: to provide maximum contact and traction for high-horsepower vehicles. The key to its performance lies in its tread compound and design. Nitto utilizes a lightweight, high-grip compound that stays sticky as it heats up, which is exactly what you need during repeated track sessions or hard acceleration runs.
This tire is designed for a very specific target audience. It’s ideal for the weekend warrior with a sports car, muscle car, or tuned import who participates in track days, autocross events, or enjoys spirited canyon driving. It’s also a top choice for drivers who struggle with wheelspin on their powerful rear-wheel-drive cars and want to put that power down more effectively. If your primary goal is to improve lap times or achieve better 60-foot times at the drag strip while still being able to legally drive to the venue, the NT555R2 is built for you.
Key specifications include its asymmetrical tread pattern, which is optimized for water evacuation (though it’s still best in dry conditions) and cornering stability. The internal construction is reinforced to handle the stresses of high-load cornering and hard launches. It’s available in a wide range of popular performance sizes to fit many modern sports cars and muscle cars. It’s crucial to note that this is a summer-only compound and should not be used in near-freezing temperatures, as the rubber can harden and lose grip.

Key Features & Performance
To understand why the NT555R2 performs the way it does, you need to look at the specific technologies and design choices Nitto made. I tested these features in real-world conditions, focusing on how they translate from a spec sheet to actual driving feel and performance on the track.
Advanced Tread Compound for Maximum Grip
The heart of the NT555R2’s performance is its specialized tread compound. This isn’t the same rubber you’d find on a standard all-season or even a typical max-performance summer tire. It’s a softer, stickier compound formulated to generate tremendous grip as it heats up. On the track, I noticed a significant difference in cornering grip compared to other street-performance tires. The tire feels like it “claws” at the pavement, providing a level of mechanical grip that inspires confidence when accelerating out of a corner. The trade-off, as with any soft compound, is a faster rate of wear, but the trade is well worth it for the level of adhesion you gain.
Asymmetrical Tread Pattern for Stability
The asymmetrical tread design is a work of art in functional engineering. The inner shoulder features larger blocks and wider grooves to help channel water away, while the outer shoulder is reinforced with more rigid blocks to resist deformation during hard cornering. On the track, this translates to excellent feedback and stability. When I was pushing through high-speed sweepers, the tire felt planted and predictable. There was no vague or squirmy feeling from the sidewalls, which is a common issue with less robust performance tires. The pattern is a perfect balance, providing enough void for water dispersion while maximizing the contact patch for dry traction.
Durable Internal Construction
Track days are brutal on tires. The combination of high speeds, lateral G-forces, and heavy braking generates immense heat and stress. The NT555R2 is built to handle this punishment. Its internal construction includes high-tensile strength steel belts and a robust carcass that resists damage and maintains stability. During my testing, even after several hot laps, the tire remained consistent. I didn’t experience the dramatic fall-off in performance that can happen with tires that overheat easily. This durability means you can spend more time on the track enjoying your car and less time worrying about degrading your tires.
Optimized for Responsive Handling
Beyond just raw grip, a good performance tire needs to communicate with the driver. The NT555R2 provides sharp and responsive handling characteristics. The turn-in is crisp, and the tire telegraphs what it’s doing at the limit. You can feel the progression of grip as you approach the tire’s maximum capability, which allows for smooth and controlled driving at high speeds. This is a marked difference from some tires that break away suddenly and without warning. For a driver looking to improve their skills and lap times, this communicative nature is invaluable.
