Features & Details

  • Superior Traction and Reliable Handling
  • Excellent Anti-Hydroplaning Characteristics
  • Directional Tread Design
NT555. The Nitto NT555 255/50-17 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 2005+ 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.

well this fit on my factory stock 17's? Looking too upgrade my tires, higher performance than stock but stay w the 17s for now. Any suggestions on other sizes u guys have? 235/50 or 235/45/17??


  • Yes these will fit on your stock 17's. 255 is the largest width that will fit well so there may be a little bit of a bulge but in the end will look beefy.

    pretty good tire

    This is the second set I have bought. The rears went really fast of course but like a couple months fast. I have them on the stock wheels on a mach 1 and I have no problem at all spinning them which is not a good thing. When driving normal they hook fine and surprisingly well in the rain too. If DRs werent so expensive id buy those but if you have a gt or v6 im sure these would be perfect.

    Great tires!

    I have owned these tires for a couple years since I upgraded my factory wheels to new rims and tires. The size is awesome and the appearance is clean and beefy which looks great on a muscle car. I recommend these tires, great traction, excellent tread life overall a good purchase for driveability.

    Great tire!

    I'm on the second set of NITTOS 555s for this car. Had the first set for over three years and I'm afraid to take a chance on anything else!... You can pay more for tires, but they will not be much better. These are a great value. Very good wet traction, although doing stupid things on wet roads don't count.

    These tires just flat out work great

    I have these tires mounted on a set of Bullet wheels and they look and fit great together. I use these tires mostly in the spring and summer and to the drags. At the track after making 3 passes with the stock 7 inch wide factory Mustang 6 cyl tires. At anything over 2000RPM using a foot brake launch they just went up in smoke. Mounted the Nitto's and the car flash stalled a few hundred RPM higher and my ET improved by 0.105. I drove a few thousand miles and they are just great and perform beyond my expectations.

    Overall, these are great tires.

    Tires are great on dry pavement. Some slight hydroplaning when driving in the rain. Obviously not a good tire for winter weather...Overall a great tire. Great quality tire at a great price. This is the only tire I will put on my GT. They also give my GT a meaner look....

    Perfect for stock 17's

    If you're looking to keep your stock wheels but improve the look of your mustang, this is the way to go. I put them on my 06 with stock 17" bullitt wheels and made a great difference in looks and ride. It really helps give it that old school muscle car stance.

    very affordable summer tire.

    My car has been on the nitto extreme 555 for about 2 weeks now and the ride is pretty smooth and not loud at all, traction is fairly good it does suffer quite a bit when road is wet, but that is to be expected from a summer tire, all in all its a very good and affordable summer tire, which can double as an all season tire if you live in a palce where it doesnt rain all that much, like in my case california.

    Great performance

    I purchased these tires for my 2005 Mustang GT. These tires provide excellent performance for the money. I have spent much more on other tires and I can't tell the difference. I tend to take corners very aggressively and I have yet to lose traction on a turn. The tread style is very aggressive and are wearing really so far. I would buy these tires again.

    Replace those OEM Pzero nero's!

    Installed these tires all the way around on my 05 mustang. I used 1" spacer on rear wheels to move the tires out a bit and the look is righteous.
