    The Nitto NT555R Exreme Drag Radial tires are designed for competitive drag racing while being D.O.T. compliant for the trip to the track and back home. This tire outperforms all drag racing radial tires while providing impressive control and handling yet still delivering up to 15,000 miles of tread life for normal street driving. These tires are constructed with a specially formulated soft racing compound to provide maximum traction.

  • Competition Performance - The overall construction has been modified to improve launch performance. The NT555R was designed to achieve a balance between maximum dry performance and occasional street use.

  • High-Speed Stability - Semi-radial construction combined with a unique reinforced package helps provide stability at high track speeds.

  • Street & Strip Consistency - The tread compound is formulated to achieve a balance between tread wear and drag strip performance, allowing for the weekend racer to drive to the track, compete, and drive back home on the same set of rear tires.

  • A Perfect Pair - The NT555R drag radial works in unison with the NT555 Extreme Street Performance Radials, so you can put the drag radials on the rear axle and the NT555s on the front axle. When developing both product lines, Nitto matched the tread pattern and sizing to fit modern performance vehicles.

  • 40450 - Nitto NT555R Extreme Drag Radial Tires is rated 4.8 out of 5 by 5.
    Rated 5 out of 5 by from So far, so great! I bought these for my 2016 Hellcat Charger for use at the track. I bought a second set of wheels, a bit wider because the stock tires are just not capable of handling all the power. I tried the Nitto's out around town for a couple of days just to get a feel and the difference is stark. SO much more grip, so much better off the line...I can't wait to try them at the track. The 0-60 times as recorded by the on board computer shows a huge improvement.

    Rated 5 out of 5 by from I'm on my second set of 555Rs they grip really good for my power level 700 rwhp. I get about 5k miles out of them with no track use.

    Rated 5 out of 5 by from They hook! First first run at the track knocked a whole second off the quarter mile time. Heat them up and they will hook. Well worth the money. For a stick car that has problems spinning the tire this is what you need. Something you can drive to the track and be confident at the track and then drive home. Drop tire pressure down to 16 or 18 pounds and let her eat.

    Rated 4 out of 5 by from Sticky Street Tires I've tried several sticky street tires but the Nitto 555R is the best "almost-practical" ;) ones I've used. They're not going to last long because there's not a lot of tread and the compound is very soft. This is by design. If you like to dig on the street or on the occasional track visit, these are the tires to do it. If you're buying tires for your daily driver, I'd suggest looking into something else. They're not meant for rain, cold weather or longevity.
