2020-2026 Toyota GR Supra A90/A91 Wheel Fitment Guide

The Toyota GR Supra (A90/A91) is the fifth-generation Supra, produced globally from 2019 and sold in North America as a 2020 model year vehicle. Co-developed with BMW and built on the CLAR platform, it offers two turbocharged RWD configurations: BMW’s B48 2.0 four-cylinder producing 255 hp and BMW’s future legend 3.0 B58 inline-six producing 382 hp.

For fitment purposes, the A90 and A91 are the same. The A91 chassis codes were reserved for Toyota’s annual special edition models such as the A91-CF Edition with different cosmetic parts and forged 19-inch wheels. The platform’s chassis architecture has two primary front fitment constraints: a double-joint MacPherson strut with tight inboard clearance envelopes, and front fender arches that cannot be rolled or modified because the clamshell hood is the fender. There is ample room in the rear to fit 11J wheels without drama.

OEM / Stock Wheel Specifications

Both the 2.0 and 3.0 share the same hub architecture.

The A90 Supra is decidedly un-Japanese in bolt pattern as it carries a 5×112 bolt pattern more commonly found on the likes of Audis, Mercedes-Benzs, and VWs. The Supra uses bolts rather than studs, seated at a 60-degree conical angle. Spherical-seat hardware will not correctly locate the wheel against the hub. Torque cold in a star pattern.

Factory Wheel Packages

Both OEM 18-inch and 19-inch wheels are wrapped in Michelin Pilot Super Sports with a Star BMW (*) designation. Though offered in different finishes, the different 3.0 Supra trim’s 19-inch wheels are all forged aluminum.

Aftermarket Considerations

Square vs. Staggered

The factory staggered configuration (narrower front, wider rear) maximizes the rear contact patch for a rear-wheel-drive platform under acceleration, but eliminates the ability to rotate tires front-to-rear. On the GR Supra, the staggered configuration is paired with a limited-slip differential that does not impose strict tread-depth matching requirements across the rear axle, unlike some BMW applications. That said, replacing both rears simultaneously when tread approaches wear limits remains best practice.

Square setups allow full rotation, which is particularly valuable for track-driven cars that consume rear tires quickly.

Front Suspension Clearance

The double-joint MacPherson strut front suspension on the A90 Supra sits with only 5–8mm of clearance between the factory spring perch assembly and the inner sidewall of the front tire at the OEM 255/40 width on the standard 9J ET32 wheel.

When certain aftermarket coilovers are installed, the threaded lower spring seats and adjustment collars sit lower on the strut body, placing the hardware directly adjacent to the tire shoulder. Running a 10J wheel with ET30 or higher offset requires a minimum 5mm hubcentric spacer on the front axle to push the wheel assembly outboard and ensure clearance over the strut body and coilover adjustment collar. Track tires with tall, square shoulders may additionally require trimming the corner of the factory metal spring plate or its rubber isolator to avoid contact.

Another contact point to check is the front lower control arms. A 10.5J or 11J with higher positive offset may contact the lower control arms at full lock. Installing Steering Rack Limiters can reduce steering angle so that “full lock” is no longer full lock.

Front Fender Arch Limitations

The front fender arches on the A90 Supra cannot be rolled or pulled like most other vehicles as the “fender” is part of the front aluminum clamshell. The inner sheet metal lips on the front arches are already compressed completely flat against the outer skin from the factory. There is no 90-degree lip remaining to bend inward. Traditional fender rolling also relies on malleable steel. Aluminum has no structural memory and is brittle. The hood assembly extends over the front wheel arches with only the plastic fender liner between the hood skin and the tire. Mounting a hub-based rolling tool is not feasible as the panel pushes away when opened and has no rigid structural backing behind it. Attempting to force an aluminum edge to stretch or pull typically causes the metal to crack, ripple, or split.

Aftermarket hoods are frequently made of composite materials which also cannot be massaged, and worse, are likely to crack on contact. In short, between the front suspension clearance and the clamshell, front fitment on the A90 is range bound and careful attention must be paid to both inner and outer clearance. When running an aggressive front setup that produces contact, the available remedies are:

• Offset, Width, and Tire Choice: In a word: fitment. Higher offset, less width, narrower tires sound less awesome, but are the answer to getting the right fitment.
• Negative Camber: Adjustable camber plates are the most effective method. Adding negative camber tilts the top of the tire inboard and moves the shoulder away from the fender edge. Using adjustable camber plates as an adjustment from the top instead of lower adjustable control arms gains slightly more clearance.
• Plastic Liner Trimming: Contact often occurs against the plastic fender liner vents rather than the metal hood skin. These sections can be carefully trimmed to clear the tire at full steering lock. If this is not done, your car may also “self-clear” itself when the tire rubs against the liner.

Brembo Brake Caliper Clearance

The Supra 3.0 ships with Brembo 4-piston brake calipers in front. These require specific wheel barrel engineering to clear when downsizing to 18-inch wheels for track use. The 348mm front rotors and Brembo caliper body create significant radial height and protrude outboard from the hub plane. Downsizing to 18-inch wheels requires an appropriate barrel profile. Some budget 18-inch wheels and many multi-piece constructions feature a stepped internal barrel that reduces diameter near the wheel face and will collide with the top of the Brembo body or balancing weights. Wheels with a flat spoke profile at high positive offsets (ET35+) may collide with the face of the caliper body.

Verified track-ready 18-inch options engineered with brake clearance in mind and high-clearance barrels include the APEX SM-10 and Titan 7 T-S5 as commonly cited examples, though this is by no means an exhaustive list. Motorsports-oriented wheels utilize a concave spoke profile to curve the spokes outward and clear the caliper’s lateral overhang without requiring thick scrub-radius-altering spacers. The Supra 2.0 uses conventional (non-Brembo) front brakes and does not have the same 18-inch caliper clearance restrictions.

Wheel Construction

The GR Supra 3.0 comes with forged 19-inch wheels from the factory. Forged wheels are produced by compressing a billet aluminum blank under high pressure, which aligns the grain structure of the metal and produces a wheel that is exceptionally strong for its weight. This means a forged wheel can achieve the same load capacity as a heavier cast wheel at a fraction of the mass. The downside is cost: forged wheels carry a significant price premium over other construction methods.

Owners upgrading to wider aftermarket wheels are frequently drawn to flow-formed options as a middle ground. Flow-forming starts with a cast blank that is then pressed and spun over a mandrel while hot, stretching and compressing the barrel to align the aluminum grain in the rim area. The result is lighter and stronger than a pure cast wheel, but it does not match a monoblock forging. The trade-off on the A90 Supra is that going wider in a flow-formed wheel may net more contact patch while costing some of the unsprung weight advantage the factory forged wheels already deliver.

2020-2022 forged OE Supra 3.0 wheels weighed in at about 24.5 lbs front and 25.6 lbs rear. The design of the wheel left a lot of unmachined material in the spokes which pushed the weight closer to that of a typical flow-formed wheel. For the 2023+ model years, Toyota redesigned the 3.0 wheels and were able to drop the weights to about 21.0 lbs front and 22.0 lbs rear, a weight more typical of aftermarket forged wheels.

The Supra 2.0 comes with cast 18-inch wheels, which means a motorsport-oriented aftermarket upgrade will likely mean an improvement in construction quality regardless of method.

Wheel Load Ratings

The GR Supra 3.0 weighs approximately 3,400 lbs. Dynamic cornering and braking loads multiply static weight significantly. When selecting aftermarket wheels, the load rating is a critical safety specification. Wheels are typically rated in kilograms per wheel, with the rating stamped on the back of the wheel barrel or documented in the manufacturer’s specifications.

The GR Supra’s gross axle weight ratings are approximately 865 kg (1,907 lbs) for the front axle and 960 kg (2,116 lbs) for the rear axle. Dividing the highest axle rating by each corner gives a minimum wheel load rating of 650 kg (1,433 lbs) per wheel as the starting point for street use. Track use, particularly at venues involving curbing, should target 720 kg (1,650 lbs) or higher. Always verify load ratings with the manufacturer before purchasing. If a manufacturer cannot provide this data, look for different wheels.

TPMS

The GR Supra uses a direct TPMS system with battery-powered sensors inside each wheel. One peculiarity is that North American-spec GR Supras transmit at 433 MHz while other regional variants such as the Japanese-market GR Supra operate at 315 MHz. If importing used wheels, you will need to verify you have the appropriate TPMS sensors. See the GR Supra A90/A91 Tire Guide for the full recalibration procedure after pressure adjustments or wheel swaps.

Centerbore and Hub Centricity

The A90 Supra’s 66.5mm centerbore requires hubcentric fitment. Aftermarket wheels are frequently made in 72.6 mm or larger bores to accommodate multiple platforms. Precision-machined aluminum hubcentric rings are required for any bore larger than 66.5mm. Spacers thicker than 3mm must be fully hubcentric with an integrated 66.5mm hub nose. Slip-on non-hubcentric spacers transfer shear forces to the M14 wheel bolts and introduce high-speed vibration. Plastic hub rings are not suitable for track use. Brake heat will melt them, complicating wheel removal and potentially leaving a mess for you to scrape off of the hub.

Wheel Spec Recommendations

The recommendations below are based on the platform’s documented clearance constraints and community fitment data. Actual fitment depends on your specific wheel’s spoke profile and barrel geometry, suspension, ride height, and alignment. Always verify fitment for your specific combination before purchasing.

OEM+ Recommendations

Conservative sizes close to or matching factory specifications. Direct bolt-on fitment at stock ride height and factory alignment settings.

Aggressive Street Recommendations

Larger contact patches and flush-to-slightly-aggressive fitments. Direct bolt-on at stock ride height for most.

The TL;DR for Aggressive Street fitments is a 10J Square or a 9.5J F paired with a 10.5J or 11J rear. The trickier decisions come to tire width decision, which may come down to availability. The rimlist rule of thumb is to choose your desired tires before you choose your wheel setup. As you can see, the permutations of staggered variations above are many. See the A90/A91 Tire Guide for a full rundown of options, including tire models available in your desired pairings.

Track / Competition Recommendations

Maximum contact patch configurations requiring camber plates and, depending on wheel width, tire choice, and coilover setup, a front hubcentric spacer for inner strut clearance.
