The 2018 Nissan GT-R sits in the modern supercar world with a reputation for all-weather capability, brutal acceleration, and a chassis that depends heavily on precise tire sizing. On this exact model, fitment is a staggered radial setup with 255/40R20 in front and 285/35R20 in the rear, both on 20-inch rims. That means the key decision is not choosing one universal size, but matching the correct front and rear tire while considering available blackwall, raised white letter, or redline presentations in the rear size. For owners balancing road use, replacement needs, and appearance, wheel position matters just as much as size.
Which Tire Size Is Right for The 2018 Nissan GT-R
The 2018 Nissan GT-R uses two primary tire sizes, and they are position-specific rather than interchangeable. Every covered trim uses 255/40R20 on the front and 285/35R20 on the rear, both in radial construction on 20-inch rims. The first step is confirming whether you are replacing a front or rear tire, then comparing the available product choices, sidewall treatments, and wheel-width requirements within that exact size.
Fit(s): Nismo Front, Premium Front, Pure Front, and Track Edition Front
Construction: Radial|Rim: 20 in
255/40R20 is a modern metric radial size in which 255 indicates nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2018 Nissan GT-R, this is the front tire size, so it plays a direct role in steering response and front-end clearance. Available options in this size include blackwall radial designs such as the BFGoodrich g-Force Phenom T/A. Choose this size when replacing the GT-R's front tires and confirm the wheel width before moving ahead with a specific product.
Fit(s): Nismo Rear, Premium Rear, Pure Rear, and Track Edition Rear
Construction: Radial|Rim: 20 in
285/35R20 is a modern metric radial size with a 285-millimeter nominal section width, a 35-series profile, radial construction, and a 20-inch rim diameter. On the 2018 Nissan GT-R, this size is used at the rear, where the car's staggered setup calls for a wider tire than the front. Rear tire choices include blackwall, raised white letter, and redline styles across series from BFGoodrich, Nitto, and Pro-Trac. Use this size when replacing the GT-R's rear tires, and compare wheel-width compatibility and intended appearance before making a final selection.
Sub-model fitment is straightforward because the covered GT-R trims share the same staggered tire arrangement. Checking the exact trim still matters, but the larger distinction is wheel position, since front and rear sizes are different across Nismo, Premium, Pure, and Track Edition applications.

2018 Nissan GT-R Nismo Front
The 2018 Nissan GT-R Nismo Front uses the shared front fitment for this model range, with a radial tire on a 20-inch rim. That makes the selection process mainly about choosing the right front-position replacement and confirming wheel-width compatibility with the tire you are considering.
The 2018 Nissan GT-R Nismo Rear uses the shared rear fitment for this model range, with a wider radial tire on a 20-inch rim. Rear replacement is where most of the visible product variety appears, including different sidewall treatments and tire series in the correct size.
The 2018 Nissan GT-R Premium Front follows the same front tire sizing pattern used across the covered GT-R trims. Tire choice here centers on maintaining the correct front size and selecting a radial option that matches the wheel and intended road use.
The 2018 Nissan GT-R Premium Rear uses the common rear tire fitment shared with the other covered trims. That means the main decision is comparing the available rear-size products by brand, sidewall style, and wheel-width suitability rather than sorting through different trim-specific sizes.
The 2018 Nissan GT-R Pure Front uses the same front tire size and radial construction found elsewhere in the 2018 GT-R range. Front replacement should stay focused on the proper wheel position, correct 20-inch fitment, and the product's compatibility with the wheel setup on the car.
The 2018 Nissan GT-R Pure Rear carries the same rear tire sizing used across the covered GT-R trims. That gives owners room to compare available rear tire styles and series while keeping the staggered layout intact.
The 2018 Nissan GT-R Track Edition Front shares the common front tire fitment used throughout the covered model range. Selection is therefore less about trim differences and more about replacing the front tire with the correct radial size for the wheel and vehicle setup.
The 2018 Nissan GT-R Track Edition Rear uses the same rear radial fitment found on the other covered GT-R trims. Owners can focus on choosing among the available rear tire brands and sidewall looks while preserving the proper front-to-rear stagger.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2018 Nissan GT-R?
The 2018 Nissan GT-R uses a staggered tire setup with 255/40R20 on the front and 285/35R20 on the rear. Both are radial sizes mounted on 20-inch rims, and the same front-and-rear pairing carries across the covered Nismo, Premium, Pure, and Track Edition applications.
The practical point is that there is no single all-around tire size for this GT-R. Front and rear positions use different widths and profiles, so replacement starts with confirming which end of the car needs tires and making sure the selected product matches that wheel position and the wheel dimensions already on the car.
What size rim does a 2018 Nissan GT-R use?
The primary tire fitments for the 2018 Nissan GT-R are built around 20-inch rims. Both the 255/40R20 front size and the 285/35R20 rear size use a 20-inch rim diameter, which keeps the staggered setup consistent while changing width and profile between the front and rear positions.
Rim diameter is only one part of the fitment story on a GT-R. The wheel position still matters, and wheel width matters as well, especially when choosing among specific front and rear tire options. A car with aftermarket wheels should have both diameter and width checked before any tire is selected.
Do all 2018 Nissan GT-R sub-models use the same tire size?
The covered 2018 Nissan GT-R sub-models share the same basic staggered arrangement rather than using different trim-specific tire sizes. Nismo, Premium, Pure, and Track Edition all use 255/40R20 in the front and 285/35R20 in the rear, both in radial construction on 20-inch rims.
That simplifies trim selection, but it does not remove the need to confirm tire position. A front tire still needs the front size, and a rear tire still needs the rear size. Checking the actual wheels on the car is also wise if the GT-R has been modified since changes to wheel width can affect product choice.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 and 285/35R20 tire set for a 2018 Nissan GT-R?
Start with the GT-R's staggered fitment and keep the correct size at each end of the car: 255/40R20 front and 285/35R20 rear. From there, compare radial construction details, wheel-width compatibility, sidewall style, and any product specifications that matter for how the car is used on the road.
A balanced choice for this GT-R is less about finding one universal tire and more about matching the front and rear properly. Owners should also consider whether the goal is a clean modern blackwall look or a more distinctive rear appearance such as raised white letter or redline, while keeping wheel compatibility in view.
What sidewall styles are available for 2018 Nissan GT-R tires?
Sidewall style depends on tire size and product line. In the available 2018 Nissan GT-R fitments, the front 255/40R20 option appears as a blackwall, while the rear 285/35R20 size is available as blackwall, raised white letter, and redline depending on the tire series selected.
That means appearance choice is greater at the rear than at the front. A buyer looking for a uniform modern presentation may prefer blackwalls front and rear, while someone wanting a more custom look may focus on the rear-only RWL or redline options. Sidewall style should be chosen after the correct size and wheel fitment are confirmed.
What brands offer tires for the 2018 Nissan GT-R?
The available brands for the 2018 Nissan GT-R include BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both the front and rear fitments, while Nitto and Pro-Trac appear in the rear 285/35R20 size, giving the rear position more brand variety than the front.
Brand choice should be considered alongside the exact tire size, tire series, and visual presentation rather than by name alone. On this GT-R, the biggest comparison opportunity is in the rear size, where sidewall treatment and series differences can matter just as much as the brand on the sidewall.
Restoration & Appearance
How does tire construction affect the appearance of a 2018 Nissan GT-R?
The 2018 Nissan GT-R uses modern radial tire sizing front and rear, so the visual effect comes less from construction changes and more from the proportions of the staggered setup and the sidewall treatment chosen. Within the available fitments, blackwall, raised white letter, and redline options create distinctly different presentations.
A blackwall setup keeps the look closest to a contemporary performance-car appearance, while RWL or redline rear tires lean toward a more personalized style. Since the GT-R is a modern high-performance platform, appearance changes should still stay within the correct front and rear sizes and be checked against the actual wheels on the car.
Does correct tire fitment matter for a 2018 Nissan GT-R restoration or collector presentation?
Correct tire fitment matters on a 2018 Nissan GT-R because the car's stance and visual balance depend on its staggered front-and-rear sizing. Using the proper 255/40R20 front and 285/35R20 rear arrangement preserves the intended relationship between the wheel openings, tire sidewalls, and overall proportions of the car.
For a collector-minded presentation, the main decision is usually visual character within the proper sizes rather than moving away from the established fitment. Sidewall treatment, brand, and tire series can all change the finished look, but the first step is keeping the GT-R's front and rear tire positions correctly matched to the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Nissan GT-R?
Yes. A 2018 Nissan GT-R with aftermarket wheels, altered offsets, suspension changes, or body modifications may need closer fitment review even when the tire size remains 255/40R20 in front and 285/35R20 in the rear. The car's staggered layout leaves less room for assumptions than a square setup would.
The safest approach is to confirm wheel diameter, wheel width, and clearance at both ends of the car before replacing tires. Lowering changes, spacer use, and wider replacement wheels can all influence steering clearance or fender clearance, so a modified GT-R should be measured rather than treated like a stock-wheel example.
What should I inspect before driving a 2018 Nissan GT-R on new tires?
Before putting miles on a 2018 Nissan GT-R with new tires, inspect basic installation points such as correct front and rear sizing, proper inflation, valve condition, and visible bead seating. It also helps to look over the wheels for damage and confirm that each tire matches the correct wheel position on the car.
A short follow-up inspection after initial road use is worthwhile on a high-performance car like the GT-R. Check for uneven clearance marks, unusual vibration, air loss, and any sign that the tire is contacting suspension or body components. A quick recheck of pressure and lug torque habits adds another layer of prudence.
How should 255/40R20 and 285/35R20 tires on a 2018 Nissan GT-R be maintained?
Maintain 255/40R20 front and 285/35R20 rear tires on a 2018 Nissan GT-R by checking pressure regularly, watching tread wear patterns, and inspecting the sidewalls for cuts, bulges, or cracking. Because the car uses different sizes front and rear, tire care starts with treating each axle position as its own fitment rather than as a shared setup.
Collector or low-use examples deserve extra attention because tires can age even when tread looks usable. Regular visual inspections, protection from prolonged sunlight and ozone exposure, and prompt attention to any vibration or air loss help preserve both the tires and the way the GT-R drives on the road.
