NT555R. The Nitto 305/40-18 NT555R is a D.O.T.-compliant competition drag radial designed with maximum flexibility for the weekend drag racer. The NT555R combines a high grip compound and semi-racing construction to provide maximum traction at the starting line. The tire comes molded at 6/32 of an inch and features a unique reinforced belt package to provide improved traction and high-speed stability. The NT555R is the perfect performance radial for the street or strip.

DOT approved. Can be run on the street, and deliver up to 15,000 miles of tread life in normal street driving. However, this soft and flexible tread will wear much quicker than tread compounds formulated for regular passenger cars.

Provides maximum traction on the track. NT555R's are manufactured with the original tread depth of 6/32nds” and are constructed with a specially formulated soft racing tread compound to provide maximum traction. High block rigidity, soft compounding and large contact patch provide extreme dry traction in race conditions. Low void ratio and large tread blocks optimize dry traction.

Designed for competition drag racing. The Nitto NT555R is designed primarily for competition drag racing, but is also very popular and exceptional on road courses, track racing, and drifting.

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 10 Inch Wheels - REAR Only

  • Directional tread design
  • Two wide steel belts and two nylon cap plies stabilize tread for superior traction and handling
  • Steel sidewall inserts provide control and stability during extreme lateral acceleration
  • Competition Drag Radial, Treadwear 100, Traction and Temperature A

NOTE: These are DOT street drag radial and racing specific compound and tread tires. They are designed to be used on the drive wheels only of your car during the summer and warm temperature months. For track or drag use, we recommend that they be appropriately "warmed up" before each run.

WARNING: Use during winter months/cold temperatures will result in structural damage leading to catastrophic tire failure! For proper winter storage and care, please see this PDF file.

They have excellent grip on the drag strip, hook up nice as long as I remember to turn the traction control back on. However after 2 days at the track they are already down to the wear indicator. Definately

    They have excellent grip on the drag strip, hook up nice as long as I remember to turn the traction control back on. However after 2 days at the track they are already down to the wear indicator. Definately going to look into an extreme high performance summer tire the next go around. If you can afford to put almost $600.00 into your tires every month then by all means these are the tires to buy.

    I can finally hook

    December 08, 2011

    I have 430rwhp and had previously ran 285/40/18 F1's on the rear. 1st thru 3rd was a handful now I have the nitto 555r DR's traction is not a big problem once the tires are heated up. The 305/40/18's really look good to.

    tire review

    June 20, 2011

    I have put about 300 miles on these. They hook up on the street way better then stockers...With that said I don't expect them to last long but I got about 640hp and point in having it if ya don't use the increased traction makes it more manageable...

    stick like glue

    May 11, 2010

    I have 350RWHP on my 2006 Mustang with 4:10 rear and can break these loose above 70 deg. The gear and tires were chaged at the same time. The 285/40 KDWs I had before broke loose with my 3.31 gears easiely. I now have 12,000 miles on them and looks like only 1-2K are left. $600 a year is well worth the 0.5 sec I picked up in the 0-60 and 1/4 mile and being able to floor it around turns.

    Daily Driver and Track tire

    October 18, 2014

    My supercharged car has 425 rwhp. This tire really grips on the street well. So much better than my previous 285 BF Goodrich did. I do about 75 passes a year at my track. Having these tires is so much easier than swapping to DRs. The grip at the track is very good. Its not a bias ply tire so its not gonna dead hook but they stick very well. I do drive these in the rain and have get great wet traction. Lastly they look amazing, there is nothing like having some wide meats on the car.

    10,000 miles and STILL biting!

    September 01, 2012

    Just like the title says, I've now put nearly 10k on these tires and they are still biting with just a little spinning. They spin a little more than when they were new in 1st, but I've also increased the power a bit. Mods are JLT, Boss IM, ORX, BBK LTH, AED e85 tune, 150 shot. My last attempt at the track yielded a 1.6 60'. The run had to be aborted due to other issues.
