Features & Details

  • Superior Traction and Reliable Handling
  • Excellent Anti-Hydroplaning Characteristics
  • Directional Tread Design
NT555. The Nitto NT555 235/50-18 is a summer-oriented, ultra high-performance street tire that was designed with the performance driver in mind. With one of the largest contact patches available, the NT555 provides superior traction and reliable handling - without sacrificing tread life. Both the tread pattern and the compound were optimized for dry performance. The highly rigid tread blocks provide stability while prolonging tire life. The NT555 will get you off the line quicker in the straights and provide confidence in the corners.

Superior traction and reliable handling. By utilizing a racing concept design, Nitto Tire's engineers developed the NT555 "Extreme ZR". With a specially formulated compound and one of the biggest contact patches available, the NT555 provides superior traction and reliable handling.

Excellent anti-hydroplaning characteristics. 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. Combined with an increase in tread block rigidity, a high modulus carcass, and hard bead filler, the NT555 delivers total vehicle control under all driving conditions.

Directional tread design. The tread pattern on the Nitto NT555 is designed for high-speed stability and superb cornering performance. High tread block rigidity secures stable contact with the road under all driving conditions.

5 Year Warranty. This Nitto Tire comes with a 5-year warranty from the date of purchase. Some limitations do apply. Please see the Full Nitto Warranty disclosure for details.

Best Fit: 18 x 8 Inch 2005+ Wheels

  • High-grip compound delivers superior mobility on both wet and dry surfaces, while ensuring a high level of anti-wear performance
  • Z Performance Rated, Treadwear 300, Traction and Temperature A

NOTE: These are extreme ultra high performance summer specific compound and tread tires. Use during the summer and warm temperature months will result in far superior traction over “all season” tires. Use during the winter months/cold temperatures drastically reduces traction and exponentially increases stopping distance as the compound becomes less sticky.

Mounting & Balancing: AmericanMuscle offers professional mounting and balancing on all wheels and tires when purchased together on the same order for an additional fee. This will allow you to swap out your old wheels for your new set when they arrive. We even offer Free Nitrogen tire fill.

    Fantastic tire at a very reasonable price

    I bought the NT555s in March and I have been blown away by the difference they make. From an "ultra high-performance" street tire I expected a major performance increase in dry conditions, and that's exactly what I have gotten. But I live in Chicago, and what has really impressed me is the way these tires have handles the less pleasant conditions. The NT555s held their own during a very late snow fall (punishment for jumping the gun on the summer tires I suppose), and have fared extremely well in the heavy rains we've had here pretty consistently this fall/summer. If you're looking for a solid entry level performance tire that lets you play, but can handle the rigors of a daily driver, look no further than the Nitto NT555s!

    nitto on my gt/cs

    It is truly amazing how much of a power increase I get from no slip, wet conditions don't mean anything anymore due to no slip performance. They look great and aggressive. I love nitto 555's, I would completely recommend them to any mustang driver and they are the only street you're I will use from this day forward! Thank you american muscle for hooking a brother up and beating everyone else's price! Fast delivery too!
