The 2023 Toyota GR Supra blends modern sports-car engineering with the long-running Supra name, giving buyers a compact rear-wheel-drive coupe with staggered tire fitment and sharp chassis responses. For tire selection, that matters just as much as horsepower, because this car uses different front and rear sizes and changes wheel diameter between the 2.0 and the 3.0-based models. The 2.0 runs 255/40R18 front and 275/40R18 rear, while the 3.0, Premium, and A91-MT Edition use 255/35R19 front and 275/35R19 rear. Available choices include blackwall performance radials, plus select redline and raised white letter options in 275/40R18 for owners who want a different visual character.
Which Tire Size Is Right for The 2023 Toyota GR Supra
Four primary tire sizes apply to the 2023 Toyota GR Supra, and the first step is identifying both the exact model and whether you are selecting a front or rear tire. The 2.0 uses 18-inch front and rear fitments, while the 3.0, Premium, and A91-MT Edition use 19-inch front and rear fitments. Once that is confirmed, the real comparison becomes tire series, sidewall treatment, and the intended balance between appearance and road use.
A 255/40R18 tire uses a 255-millimeter section width, a 40-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2023 Toyota GR Supra, this is the front size for the 2.0 and it is part of the car’s staggered setup rather than a universal fitment for every version. Available choices center on BFGoodrich blackwall performance series including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This size is the one to evaluate when replacing the front tires on an 18-inch-wheel GR Supra 2.0 while keeping wheel size and front axle fitment aligned.
A 275/40R18 tire keeps the same 18-inch rim diameter but adds width compared with the 2.0’s front tire, using a 275-millimeter section width and a 40-series profile. This is the rear size for the 2023 Toyota GR Supra 2.0, so it should be treated as a rear-position fitment within the factory-style staggered arrangement. Product choices include BFGoodrich and Nitto blackwall radials, along with Pro-Trac Street Pro III options in redline and RWL sidewall styles. This size matters when maintaining the proper front-to-rear relationship on an 18-inch GR Supra setup instead of selecting by diameter alone.
Fit(s): 3.0 Front, A91-MT Edition Front, and Premium Front
Construction: Radial|Rim: 19 in
A 255/35R19 tire combines a 255-millimeter section width with a lower 35-series profile and radial construction on a 19-inch rim. On the 2023 Toyota GR Supra, this size is used at the front of the 3.0, Premium, and A91-MT Edition models, so it belongs with the 19-inch staggered package rather than the 18-inch 2.0 setup. BFGoodrich offers several blackwall choices here, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. This is the front size to confirm when replacing tires on the higher-trim GR Supra models that carry 19-inch wheels.
Fit(s): 3.0 Rear, A91-MT Edition Rear, and Premium Rear
Construction: Radial|Rim: 19 in
A 275/35R19 tire uses a wider 275-millimeter section width, a 35-series aspect ratio, radial construction, and a 19-inch rim diameter. For the 2023 Toyota GR Supra, this is the rear tire size on the 3.0, Premium, and A91-MT Edition, completing the car’s staggered 19-inch arrangement. Available blackwall options include multiple BFGoodrich g-Force series as well as the Nitto NT555 G2, giving buyers useful variety within the same fitment. This size should be matched to the rear axle of the 19-inch-wheel cars after confirming the exact model and wheel setup.
Tire fitment on the 2023 Toyota GR Supra varies by model and by axle position, so identifying the exact version of the car is essential before choosing tires. The main split is between the 18-inch 2.0 setup and the 19-inch fitment used on the 3.0, Premium, and A91-MT Edition.

2023 Toyota GR Supra 2.0 Front
The 2023 Toyota GR Supra 2.0 front fitment uses a 255/40R18 radial, making it part of the car’s 18-inch staggered arrangement. Tire selection here should stay focused on the proper front size and on choosing the right blackwall performance series for the intended road use.
The 2023 Toyota GR Supra 2.0 rear fitment uses a 275/40R18 radial, wider than the front tire and matched to the 18-inch rear wheel. This is also the position where sidewall presentation expands to include blackwall, redline, and RWL choices, so appearance may become part of the decision.
The 2023 Toyota GR Supra 3.0 front fitment uses a 255/35R19 radial, moving to a 19-inch wheel and lower-profile tire package. Replacements should be chosen with that 19-inch front setup in mind rather than mixed with the 18-inch fitments used on the 2.0.
The 2023 Toyota GR Supra 3.0 rear fitment uses a 275/35R19 radial as the rear half of the 19-inch staggered combination. Tire choice here centers on keeping the correct rear size while comparing available blackwall performance series from BFGoodrich and Nitto.
The 2023 Toyota GR Supra A91-MT Edition front fitment uses a 255/35R19 radial, the same front size used by the other 19-inch-wheel models. The practical decision is choosing among the available blackwall tire series while preserving the correct front profile and rim diameter.
The 2023 Toyota GR Supra A91-MT Edition rear fitment uses a 275/35R19 radial on a 19-inch rim. Matching that rear size correctly matters for maintaining the staggered setup, and the available choices allow comparison across several blackwall performance radial lines.
The 2023 Toyota GR Supra Premium front fitment uses a 255/35R19 radial, sharing the same front size as the 3.0 and A91-MT Edition. Tire selection is therefore straightforward once the model is confirmed, with the main differences found in series choice rather than size.
The 2023 Toyota GR Supra Premium rear fitment uses a 275/35R19 radial, completing the 19-inch staggered arrangement shared with other 3.0-based versions. The key is selecting a rear tire in the proper size and construction while comparing blackwall performance options that suit the car’s use.
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.

Available 2023 Toyota GR Supra tire choices span 18-inch and 19-inch radial fitments from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare blackwall performance series across all four sizes, with added redline and RWL styling options in 275/40R18.
The most important GR Supra tire questions usually come down to front-versus-rear sizing, 18-inch versus 19-inch wheel fitment, available radial choices, and how to match the right tire series and sidewall style to the exact model.
Tire Size & Fitment
What tire size fits a 2023 Toyota GR Supra?
The 2023 Toyota GR Supra uses four primary tire sizes, depending on model and axle position. The 2.0 uses 255/40R18 in front and 275/40R18 in the rear, while the 3.0, Premium, and A91-MT Edition use 255/35R19 in front and 275/35R19 in the rear.
That means tire selection starts with confirming both the exact GR Supra version and whether the tire is for the front or rear axle. The car uses a staggered setup, so front and rear sizes are intentionally different, and the 18-inch and 19-inch packages should not be treated as interchangeable without checking the wheel setup.
What size rim does a 2023 Toyota GR Supra use?
A 2023 Toyota GR Supra uses either 18-inch or 19-inch rims, depending on the model. The 2.0 uses 18-inch front and rear tire fitments, while the 3.0, Premium, and A91-MT Edition use 19-inch front and rear fitments.
Rim diameter should be confirmed before looking at tread design, brand, or sidewall style. A 255/40R18 and a 255/35R19 may share similar overall diameter, but they are built for different wheel diameters, so checking the actual wheel on the car is the first fitment step, especially if wheels have ever been changed.
Why does the 2023 Toyota GR Supra have more than one tire size?
The 2023 Toyota GR Supra has more than one tire size because fitment changes by model and by axle position. The 2.0 uses an 18-inch staggered setup, while the 3.0, Premium, and A91-MT Edition use a 19-inch staggered setup, with narrower tires in front and wider tires in the rear.
This is normal for a modern performance coupe and helps explain why tire shopping for a GR Supra is not a one-size-fits-all task. The practical takeaway is to verify the exact model, confirm front or rear position, and check the wheel diameter already on the car before selecting from the available radial tire options.
Choosing the Right Tire
What should I consider when choosing a 2023 Toyota GR Supra tire?
Start with the exact size for the model and axle position, since the 2023 Toyota GR Supra uses staggered front and rear fitments and two different wheel diameters across the range. From there, compare radial tire series, brand offerings, sidewall presentation where available, and wheel-width compatibility within the correct size.
The best comparison is usually between tires that share the same size but differ in series character or visual treatment. It also helps to match the tire to how the car is used, whether that means general street driving, a sportier feel, or preserving a certain look, especially on the 275/40R18 rear size.
What sidewall styles are available for 2023 Toyota GR Supra tires?
Most available 2023 Toyota GR Supra tire options use a blackwall sidewall, especially in the BFGoodrich and Nitto performance radial lines. The main exception is the 275/40R18 rear size for the GR Supra 2.0, where Pro-Trac Street Pro III options add redline and RWL sidewall treatments.
That means sidewall appearance is mostly a factor for owners shopping the 18-inch rear fitment rather than the full range of Supra sizes. A blackwall keeps the presentation modern and understated, while redline or raised white letter styling creates a more distinctive visual statement without changing the vehicle’s required rim diameter.
What brands offer tires for the 2023 Toyota GR Supra?
Available tire brands for the 2023 Toyota GR Supra include BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across all four primary fitments, Nitto is available in the wider rear sizes, and Pro-Trac appears in 275/40R18 with distinctive sidewall styling options.
Brand choice should still come after confirming the correct front or rear size and the wheel diameter on the car. Once that is settled, comparing series within a brand or comparing sidewall presentation across brands becomes more useful than choosing by name alone, especially on a staggered sports-car fitment like the GR Supra.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Toyota GR Supra?
Yes, modifications can affect tire fitment on a 2023 Toyota GR Supra even when the nominal tire size stays close to stock. Aftermarket wheels, altered wheel width, different offset, suspension changes, or lowering can all influence how a 255/40R18, 275/40R18, 255/35R19, or 275/35R19 tire sits in the car.
A modified GR Supra should be checked for inner clearance, outer fender clearance, and steering travel before assuming a familiar size will behave the same way. Verifying the actual wheel diameter and width already on the car is especially important, since the Supra range includes both 18-inch and 19-inch factory-style fitments.
What should I inspect before driving a 2023 Toyota GR Supra on new tires?
Before driving a 2023 Toyota GR Supra on new tires, inspect wheel condition, confirm the correct size on each axle, and check inflation pressure carefully. It is also smart to look over valve stems, verify that front and rear tires were not reversed, and make sure the wheels and tires clear suspension and body components.
A short recheck after the first miles is worthwhile on a staggered setup like the Supra’s. Watch for vibration, unusual rubbing, or uneven seating, and keep an eye on air loss during the first days of use so any mounting, balancing, or clearance issue is caught before it becomes a larger problem.
How often should tires on a 2023 Toyota GR Supra be inspected?
Tires on a 2023 Toyota GR Supra should be inspected regularly, not just when tread looks worn. Frequent checks for pressure, uneven wear, cuts, punctures, sidewall damage, and embedded debris are especially important on a performance-oriented car that uses different front and rear tire sizes.
Routine inspection also helps catch issues created by alignment changes, pothole impacts, or a wheel problem before they affect the car’s handling. Since the GR Supra uses a staggered arrangement, each axle should be evaluated on its own terms rather than assuming wear or condition will match from front to rear.
