The 2021 Nissan GT-R sits at the modern end of a long performance lineage, combining supercar-level speed with the all-weather confidence and daily usability that helped define the nameplate in recent years. Buyers looking at tire fitment for this exact car are dealing with a staggered setup rather than a one-size arrangement, using 255/40R20 up front and 285/35R20 at the rear, both in radial construction on 20-inch rims. That makes tire selection as much about front-to-rear balance as size itself, with choices that range from blackwall performance radials to more distinctive sidewall treatments on the rear size. Before choosing, confirm whether you are replacing front tires, rear tires, or the full set.
Which Tire Size Is Right for The 2021 Nissan GT-R
The 2021 Nissan GT-R uses two primary tire sizes, and the difference is tied to front and rear fitment rather than different wheel diameters or mixed construction types. Both sizes are radial tires for 20-inch rims, so the first step is confirming whether you are selecting a front tire or a rear tire. Once that is clear, the real comparison becomes brand, tire series, sidewall style, and wheel-width compatibility within the correct position-specific size.
Fit(s): Nismo Front, Premium Front, and T-Spec Front
Construction: Radial|Rim: 20 in
255/40R20 is a metric radial size in which 255 refers to nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2021 Nissan GT-R, this size serves the front position and is part of the car’s staggered performance setup. Available choices in this size include BFGoodrich in the g-Force Phenom T/A series with a blackwall sidewall. It is the size to evaluate when restoring correct front-to-rear tire proportions or replacing front tires while keeping wheel compatibility in line with the car’s 20-inch front fitment.
285/35R20 is a wider metric radial size, with 285 indicating nominal section width in millimeters, 35 indicating the aspect ratio, and 20 identifying the rim diameter in inches. On the 2021 Nissan GT-R, this is the rear tire size and it works with the car’s wider rear footprint. Product choices in this size span BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments represented across multiple series. This is the size to focus on when rear traction, appearance, and wheel-width suitability are the key parts of the replacement decision.
Fitment stays consistent across the covered 2021 Nissan GT-R sub-models because each one uses the same staggered front-and-rear size pairing. Checking the exact front or rear position still matters, since tire choice depends on where the tire is mounted rather than on a different rim diameter or construction type.

2021 Nissan GT-R Nismo Front
The 2021 Nissan GT-R Nismo Front uses the front tire size in the GT-R staggered setup, with radial construction on a 20-inch rim. For selection, the focus is on choosing the correct front-position tire and then comparing series and wheel-width compatibility rather than searching for a separate Nismo-only front diameter.
The 2021 Nissan GT-R Nismo Rear uses the wider rear tire size that completes the staggered GT-R fitment, again in radial construction on a 20-inch rim. That makes rear-tire selection more about choosing the correct width and comparing available sidewall and series options than about changing to a different rim size.
The 2021 Nissan GT-R Premium Front follows the same front fitment pattern used across the covered GT-R lineup, with a radial tire on a 20-inch wheel. Buyers replacing this position should verify front placement first, then compare the available tire series and wheel-width range that suit the front setup.
The 2021 Nissan GT-R Premium Rear uses the same rear size found across the covered GT-R sub-models, paired with radial construction and a 20-inch rim. That keeps fitment straightforward, but rear replacement still calls for attention to the correct position, available brands, and the appearance options offered in the wider rear size.
The 2021 Nissan GT-R T-Spec Front shares the same front tire fitment used by the other covered GT-R variants, keeping the front side of the staggered setup consistent. Tire selection here centers on front-position sizing, radial performance characteristics, and making sure the wheel setup still matches the intended front specification.
The 2021 Nissan GT-R T-Spec Rear uses the shared rear tire size for the model range, with a radial tire mounted on a 20-inch wheel. Choosing for this position means confirming the rear application first, then deciding among the available brands, tire series, and sidewall treatments offered in the rear size.
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.

These 2021 Nissan GT-R tire FAQs focus on the staggered front-and-rear sizes, 20-inch rim fitment, product selection, sidewall options, and the checks that matter before road use or after wheel and suspension changes.
Tire Size & Fitment
What tire size fits a 2021 Nissan GT-R?
The 2021 Nissan GT-R uses a staggered tire setup with 255/40R20 on the front and 285/35R20 on the rear. Both are radial tire sizes mounted on 20-inch rims, so the car does not use the same size at all four corners.
That means the first fitment decision is identifying the tire position, not just the vehicle. Front and rear tires serve different roles in the setup, so replacing one end with the other size is not the right approach. If the car has aftermarket wheels or a non-stock suspension setup, confirm the actual wheel dimensions and clearance before choosing a replacement.
What size rim does a 2021 Nissan GT-R use?
The 2021 Nissan GT-R uses 20-inch rims with both of its primary tire sizes. The front 255/40R20 and rear 285/35R20 are both built around a 20-inch wheel diameter, even though the widths and profiles differ between front and rear.
Rim diameter is only one part of fitment, so matching the 20-inch diameter alone is not enough. Wheel width still matters, especially on a staggered performance car. A rear tire such as 285/35R20 should be checked against the actual rear wheel width, while the front tire should be matched to the front wheel setup rather than assumed to interchange.
Do all 2021 Nissan GT-R sub-models use the same tire size?
The covered 2021 Nissan GT-R sub-models share the same size pattern: 255/40R20 at the front and 285/35R20 at the rear. That applies across the Nismo, Premium, and T-Spec front and rear fitment positions listed for this model year.
Fitment is straightforward across those sub-models, but position still matters because the GT-R uses a staggered arrangement. A buyer choosing tires should confirm whether the need is for front replacement, rear replacement, or a full set. It is also smart to inspect the current wheel setup, since any prior wheel change can affect width compatibility even when the rim diameter stays at 20 inches.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2021 Nissan GT-R?
For the front 255/40R20 position on a 2021 Nissan GT-R, start with the correct size, radial construction, and 20-inch rim fitment. The available option in this size is a BFGoodrich g-Force Phenom T/A blackwall tire, so the choice is less about sidewall style variety and more about matching the intended front application.
The front tire should also be checked against the actual wheel width on the car. In this size, the listed rim-width range is 8.5 to 10 inches, which makes wheel compatibility part of the selection process. Buyers replacing only the front pair should also keep the GT-R’s staggered layout in mind so the front tire remains properly matched to the rear size strategy.
What sidewall styles are available for 2021 Nissan GT-R tires?
Sidewall style variety shows up most clearly in the 285/35R20 rear size for the 2021 Nissan GT-R. Blackwall options are available, and the rear size also includes raised white letter and redline treatments through Pro-Trac offerings in the Street Pro III series.
That makes sidewall choice part of the visual decision, especially if the car is being tailored toward a more traditional muscle-inspired look or a cleaner modern presentation. The front 255/40R20 fitment is more limited, so buyers planning a matched appearance should compare how the front and rear sidewall treatments will look together before settling on a mixed-position combination.
What brands offer tires for the 2021 Nissan GT-R?
Tire options for the 2021 Nissan GT-R include BFGoodrich, Nitto, and Pro-Trac, depending on size and position. BFGoodrich appears in both the front 255/40R20 and rear 285/35R20 sizes, while Nitto and Pro-Trac are represented in the rear 285/35R20 fitment.
Brand choice should still come after confirming the correct front or rear size. On this car, the rear position offers the broadest comparison across tire series and sidewall treatments, while the front size is more narrowly focused. Buyers should compare the tire’s intended position, construction, rim-width compatibility where stated, and the visual style they want from the finished setup.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Nissan GT-R?
A period-style approach on a 2021 Nissan GT-R usually starts with keeping the correct staggered sizing intact: 255/40R20 in front and 285/35R20 in the rear. Because this is a modern performance car with radial 20-inch fitment, the visual decision is less about vintage construction and more about whether the tire presents a clean blackwall look or something more expressive at the rear.
Rear options such as blackwall, raised white letter, and redline can change the car’s character noticeably. A blackwall setup keeps the presentation closer to a contemporary high-performance appearance, while the other rear sidewall treatments push the look in a more customized direction. Buyers concerned with preserving the model’s original visual intent should compare current tire appearance against period photos and model-specific references.
How does tire construction affect the appearance of a restored 2021 Nissan GT-R?
On a 2021 Nissan GT-R, tire construction does not create a bias-ply-versus-radial appearance decision because the primary fitment is radial. The visual difference comes more from sidewall treatment, tread presentation, and keeping the correct front-and-rear size relationship than from choosing between old and modern construction types.
That makes size accuracy and overall presentation especially important. A GT-R that keeps its 255/40R20 front and 285/35R20 rear setup will usually look more settled and intentional than one with mismatched sizing. For a restoration-oriented or collector-minded result, the main question is whether the sidewall style supports a clean modern performance look or a more personalized visual statement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Nissan GT-R?
Yes. A 2021 Nissan GT-R may have the correct factory-style tire sizes on paper, but aftermarket wheels, altered offsets, suspension changes, or ride-height adjustments can all affect how 255/40R20 front and 285/35R20 rear tires sit in the car. Even with the same 20-inch rim diameter, width and clearance can change.
That is why the current setup should be inspected before replacing tires, especially on a car that may have been customized. Check wheel width, steering clearance at the front, and fender and suspension clearance at both ends. A staggered performance car leaves less room for assumptions, so the safest path is confirming the actual wheel and chassis configuration already on the vehicle.
What should I inspect before driving a 2021 Nissan GT-R on new tires?
Before road use, inspect the wheel diameter and width, verify that the new tires are mounted in the correct front and rear positions, and confirm proper inflation. It is also wise to look over valve stems, wheel condition, and any signs of rubbing or tight clearance once the tires are installed.
A short low-speed check can reveal steering interference, vibration, or contact that is easier to correct before a longer drive. On a 2021 Nissan GT-R, this matters because the staggered setup depends on keeping the front and rear sizes where they belong. After installation, recheck pressure and give the car another visual clearance inspection once it has settled under normal weight.
How often should tires on a 2021 Nissan GT-R be inspected?
Tires on a 2021 Nissan GT-R should be inspected regularly, not only by mileage but also by time and use pattern. Look at tread wear, air pressure, cuts, bulges, and sidewall condition, and pay close attention if the car sees spirited driving, long periods of storage, or seasonal use.
Performance cars can reveal alignment or pressure issues quickly, especially with wider rear tires and a staggered footprint. A visual check before drives and a more thorough inspection at routine service intervals helps catch uneven wear or slow air loss early. Stored collector vehicles also deserve extra attention, since age, heat, and long stationary periods can affect tire condition even when miles stay low.
