Features & Details

  • Superior Traction and Reliable Handling
  • Excellent Anti-Hydroplaning Characteristics
  • Directional Tread Design
The Nitto Tire NT555 255/40ZR17 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: 17 x 9 Inch 1994-1998 Wheels

  • High-grip compound delivers superior mobility on both wet and dry surfaces, while ensuring a high level of anti-wear performance
  • W 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.

    I bought these for my bolt on 98 Gt. They offer good traction in dry, plus equally good traction in the rain. They lasted me two years of very aggressive street driving, and I'd buy them again!

    Nitto NT555

    I put these 255/40-17 on the front to match the Nitto 275/40-17 on the back and I cannot believe how awesome these tires are! I had new BF Goodrich on before and they would break lose easy. These Nittos stick like glue and made my car drive better then ever. What also really surprised me that it seems to ride better? Go figure? I would recommend these tires and American Muscle to anybody. Great company and service along with great prices. These Nitto tires look awesome on my 03 Cobra wheels that I bought from American Muscle. Thanks,

    Nitto NT555

    I ordered these tires and they came the next day. I highly recommend once installed drive easy for the first few miles to get the oils off the tires. They fit my 17x8 chrome 01 cobra rims and they are amazing. No road noise, The price is perfect, I've had tires that were double the price but lacked quality. The ride quality is great and the grip is amazing. I do plan on buying 275's and putting my 255 up front. I highly recommend this tire. Nitto NT555 are by far the best tire I have had so far.

    I HAD sumitomo tires before. These are a softer material that allow me to drive like a moron and still control my car with ease. Performs well in rain and dry. These haven't skipped a beat yet. love them so far.

    Best Choice in Tires

    I already knew how well you can count on NITTO for quality in their tires because I have been running Nitto on all my vehicles for about 8 years. Their quality has continued in these NT555ZR17's, that's a no brainer. The appearance, tread design, and stance these 255/40/17's provide is outstanding. I put these on my 94 GT and drove in city driving conditions and interstate high speeds and experienced nothing but comfort and controlled response from them. Don't blame these tires for poor steering response, you probably have other suspension issues. Very low if any road noise also. Thanks AM!

    waste of money

    These tires were on my 2003 GT for about 15,000 miles if that before i had to have them replace. They gave great traction for the first 10,000 but after that it was like driving aroundwith slicks. Waste of money!!

    Great tire, I could track it from American Muscle in shipping and when installed it makes the car ride much smoother than the 245s I was using stock. I highly recommend these tires. These tires really stick to the ground.

    Wicked awsome

    I had just spent almost 800 on new tires that fitted my stock rims. Well I bought the new salleen wheels and this new tires wouldn't fit. So then I went to buy new tires from a local tire Co I have done business for years with. Big mistake. The price AM gave me for 4 new tires is less than the local Co wanted for only 2!!!! The tires I got look sick. I love the look. The way they stick to the road is crazy. I couldn't be happier. Trust me you want regret it. Don't make my mistake. If your getting rims get the package. It will save you big time. AM is the best company ever. I won't do business with anyone else.

    Best tire ever! Awesome traction! Been through thunder storms with torrential down pour, never lost traction, front or rear. I run 285/30/18 rear, and 255/40/17 front. No issues. Awesome highway handling. No worries about torque steer. I recommend them for street and highway hussle.
