About the Nitto NT555RII

Engineered for the Strip, Street-Legal Ready

Best forSports car and muscle car owners who run staggered fitments and want a DOT-legal drag-focused tire on the drive axle for both track days and street use.

The Nitto NT555RII is a DOT-approved drag racing tire built for sports cars and performance vehicles that see both strip and street duty. Its directional tread compound and stiffened sidewall are purpose-built to maximize traction at launch, making it the go-to rear-axle tire for drivers who demand serious straight-line performance without sacrificing street legality.

A specialized racing compound sits atop a directional tread pattern featuring wide twin center ribs that keep a large contact patch planted from a dead stop. The reinforced sidewall resists flex under hard acceleration to improve hookup off the line. Nitto engineered the NT555RII specifically for staggered fitment setups, pairing it on the drive axle alongside the NT555 G2 on the non-drive axle.

Questions about this tire

What does P275/40R18 94W mean?

275 is the tread width in millimeters, 40 means the sidewall is 40% of that width, and R18 is the 18-inch rim it mounts on. 94 is the load index (1,477 lbs per tire), and W is the speed rating (up to 168 mph).

Can I drive the NT555RII on public roads every day?

Yes — the NT555RII carries DOT approval, so it is legal for street use. That said, its racing compound is optimized for dry traction and acceleration, not everyday comfort or wet-weather performance, so it is best suited for drivers who split time between the strip and the street rather than pure daily commuters.

What tire is the NT555RII meant to be paired with?

Nitto specifically designed the NT555RII for staggered fitment setups, where it mounts on the drive axle and the Nitto NT555 G2 is used on the non-drive axle. This combination balances maximum launch grip at the rear with the NT555 G2's all-around street performance at the front.

How does the reinforced sidewall help at the dragstrip?

A stiffer sidewall limits the sidewall flex that normally occurs under hard acceleration, keeping more of the tire's contact patch in contact with the surface during launch. The result is improved hookup and more consistent power transfer to the pavement.

Is the NT555RII suitable for wet roads or winter conditions?

The NT555RII is not rated for severe snow service and carries no Three-Peak Mountain Snowflake certification. Its racing compound and tread design prioritize dry grip, so performance in wet or cold conditions will be limited. Drivers in climates with rain or winter weather should plan accordingly and consider a separate tire for those conditions.

Does the NT555RII come with a mileage warranty?

Warranty coverage for the NT555RII follows the manufacturer's policy — please contact us or check Nitto's current terms for specifics, as racing-compound tires often carry different warranty terms than standard passenger tires.

Buying from TFS Wheels

Shipping, returns & guarantees

Authorized Dealer — 100% Brand New Wheels & Tires

TFS Wheels is an authorized dealer for every brand we carry. Every wheel and tire we ship is brand new, unused, and packaged in its original manufacturer's box. We never sell refurbished, demo, or return-stock product. All manufacturer warranties apply and our warehouse is staffed by people who only handle wheels and tires — no in-transit damage, no test-fits, no surprises.

Free Shipping (Lower 48)

Free shipping on every order — wheels, tires, and accessories — to the contiguous United States. No minimum order, no hidden fees.

Standard delivery is 4–7 business days; expedited is 1–4 business days. Orders placed before 1:00 PM ET typically ship the same day. We do not ship internationally or to PO boxes.

Fitment Guarantee

If a wheel or tire marked "Direct Fit" or "Aftermarket Fit" for your vehicle arrives and does not fit as expected, we cover both the restocking fee and return shipping. The same applies if the bolt pattern does not match — provided your vehicle information was submitted at checkout.

To qualify for the guarantee, enter your year, make, model, and submodel before placing the order.

Manufacturer's Warranty

Every wheel and tire is covered by the full manufacturer's warranty against defects in materials and workmanship. Coverage terms vary by brand — most cover structural integrity for the life of the wheel and finish for 1 to 2 years from purchase. If you ever have a warranty question, contact us first; we work directly with the manufacturer on your behalf so you don't have to.

Accessories Included with Your Order

When you submit your vehicle information at checkout, the right lug nuts and (if needed) hub-centric rings are automatically added to your cart in the correct sizes — no guessing, no separate ordering.

TPMS sensors are also available in the cart. We program each sensor to your vehicle's exact year, make, model, and submodel before shipping, so they arrive ready to sync with your truck or car the moment they're installed. This typically saves customers the dealer or installer's programming fees, which often run several dozen dollars per wheel.

Returns

Returns are accepted within 30 days of purchase on items in new, unused condition. A 25% restocking fee applies to general (change-of-mind) returns, and the buyer covers return shipping.

The restocking fee and return shipping are waived for incorrect items, transit damage, or fitment issues when vehicle information was provided at checkout. Single wheels, single tires, mounted items, special orders, and accessories (lug nuts, locks, hub-centric rings, TPMS sensors, installation kits) are final sale.
