Best Forged Wheels for Toyota GR Supra A90/A91 — Complete Fitment Guide

The GR Supra runs one of the most wheel-friendly platforms in the sports car segment — 5×112 bolt pattern, staggered OEM sizing, and enough arch clearance to run serious aftermarket fitment without major modification. Here's everything you need to spec the right forged wheels for the A90/A91 platform.

Toyota GR Supra Factory Wheel Specs

• Bolt pattern: 5×112
• Centre bore: 66.5mm
• Thread pitch: M14×1.25
• Bolt torque: 103 ft-lbs

The 5×112 pattern is shared with Audi, BMW, and Mercedes — the most common performance bolt pattern in Europe. This means the widest selection of quality aftermarket wheels of any bolt pattern, including virtually every premium forged manufacturer.

Important: Most aftermarket wheels are machined with a larger centre bore than 66.5mm and require hub-centric rings to seat correctly. Custom forged wheels machined to exactly 66.5mm eliminate this — no rings, no vibration risk.

OEM Wheel Sizes by Variant

The Supra runs a staggered setup from the factory — wider rear than front — which suits the rear-wheel-drive platform.

Variant	Front	Rear	Front Tyre	Rear Tyre
2.0L	18×9 ET32	18×10 ET40	255/40R18	275/40R18
3.0L	19×9 ET32	19×10 ET40	255/40R19	275/40R19

Square vs Staggered Setup — Which to Choose

Staggered (Different Front/Rear Width)

Follows the factory philosophy — narrower front, wider rear. More rear contact patch means more grip under power, which suits the RWD layout. The trade-off: you can't rotate tyres, and front/rear sets must be specced independently.

Recommended staggered aftermarket (19"):

• Front: 19×9 ET25–28 | 255/35R19
• Rear: 19×10 ET28–38 | 275/35R19

Square (Same Size All Round)

Running the same wheel and tyre size on all four corners allows tyre rotation — useful if you want even wear on expensive performance rubber. Also simplifies the order: one spec for all four. Works well for track use where tyre rotation strategy is important.

Recommended square aftermarket (19"):

• All corners: 19×10 ET28–38 | 275/35R19

Aftermarket Size Recommendations

Conservative — Closest to Stock

Add half an inch to OEM width, reduce offset 10mm. Gives a slightly more aggressive look while staying well within clearance on stock suspension.

• Front: 19×9.5 ET22 | 265/35R19
• Rear: 19×10.5 ET30 | 285/35R19

Moderate — Most Popular

The most common setup for street builds on stock or mildly lowered Supras. Good fitment without rubbing on stock suspension.

• Front: 19×9.5 ET22 | 275/35R19
• Rear: 19×10.5 ET30 | 295/35R19

Aggressive — Lowered Cars

For cars on coilovers. The reduced ride height improves arch fill significantly. Clearance must be verified for your specific coilover setup — these specs are not confirmed for stock suspension.

• Front: 19×9.5 ET18–22 | 275/35R19
• Rear: 19×10.5 ET25–28 | 305/30R19

Note on 305 rear: 305/30R19 runs slightly smaller diameter than 305/35R19 — this matters for arch clearance and is the recommended profile if running 305 width.

20" on the GR Supra

20" wheels work on the A90/A91 but require low-profile tyres (30-aspect ratio) and look significantly better on lowered cars. On stock suspension with 20" wheels and 30-profile rubber, the ride quality degrades noticeably and the visual proportions require lowering to look right. If the car is staying on stock suspension, 19" is the correct call.

Brake Clearance Notes

OEM Supra brakes fit all standard aftermarket 19" wheels without issue. The higher-spec Brembo package fitted to some 3.0L variants requires clearance verification — specify your brake setup when ordering and we confirm before manufacturing.

Frequently Asked Questions

What bolt pattern is the Toyota GR Supra?

The Toyota GR Supra A90/A91 uses a 5×112 bolt pattern with 66.5mm centre bore and M14×1.25 thread pitch. This is the same bolt pattern as Audi, BMW, and Mercedes performance vehicles.

Should I run square or staggered wheels on the GR Supra?

Staggered follows the factory philosophy and gives more rear grip for the RWD platform. Square allows tyre rotation and is popular for track use. For street builds prioritising aesthetics and performance, staggered with 19×9.5 front and 19×10.5 rear is the most common choice.

What is the best wheel size for GR Supra?

19" is the optimal size for the A90/A91 — matches the factory 3.0L spec, fits 35-aspect ratio tyres which maintain good sidewall, and looks proportional on the Supra's body. 20" works but requires 30-profile rubber and looks better on lowered cars.

Do aftermarket wheels need hub-centric rings on the GR Supra?

Most catalog aftermarket wheels are made with a larger centre bore than the Supra's 66.5mm and require hub-centric rings to centre correctly. Custom forged wheels machined to exactly 66.5mm eliminate this requirement entirely.

What offset should I run on GR Supra aftermarket wheels?

For 19×9.5 front: ET22–25. For 19×10.5 rear: ET28–30. These are the most common street fitment targets that fill the arch properly on stock suspension without rubbing.
