Toyota GR Supra A90/A91 Tyre Size and Modified Fitment Guide Australia
Quick answer
Toyota Australia's final published GR Supra range used staggered tyres: GT used 255/40ZR18 95Y front and 275/40ZR18 99Y rear; GTS used 255/35ZR19 96Y front and 275/35ZR19 100Y rear. GR Supra was discontinued in Australia from August 2025. Always order the front and rear as a matched vehicle-specific set and confirm the placard.

Staggered-fitment checks
- Confirm GT, GTS or Track Edition and manual/automatic build.
- Keep the correct front/rear rolling-diameter relationship.
- Check directional/asymmetric mounting, pressures, TPMS, balance and alignment.
- Do not rotate staggered tyres front to rear.
- Inspect inner-edge wear before replacing only one axle.
