What size tires come on Supra wheels?
The tire sizes that come on Toyota GR Supra wheels depend on the trim and year. In general, base 2.0 models with 18-inch wheels use narrower front tires than the rear, while higher-performance 3.0 and special editions with 19-inch wheels use larger, wider tires on all corners.
To understand what you’ll find on a factory-equipped Supra, it’s helpful to break down the configurations by wheel size and model year. The imprints on the tires and the owner’s manual are the best references when verifying for a specific car, as regional variations can occur.
Tire sizes by wheel size
Below are the stock tire sizes commonly found on GR Supra models, organized by wheel diameter. These configurations are representative of recent model years and may vary slightly by market or edition.
- 18-inch wheels (GR Supra 2.0, base): 225/40R18 front and 255/40R18 rear
- 19-inch wheels (GR Supra 3.0, Premium/Track/A91 editions): 255/40R19 front and 275/40R19 rear
These sizes reflect the factory equipment most buyers encountered on standard trims with the two main wheel-size options. If your Supra has a special edition or regional package, sizes can differ by a small margin, so always confirm from the tire sidewall or the vehicle’s documentation.
Notes on tires and fitment
The GR Supra’s factory tires are typically Michelin Pilot Sport 4S for performance balance and grip. When replacing tires or changing wheels, it’s important to maintain the correct overall diameter to avoid dashboard and speedometer discrepancies, and to preserve handling characteristics.
If you’re considering aftermarket wheels or alternative tire sizes, consult a qualified tire and wheels professional to ensure proper clearance and alignment. Some combinations may require adjustments to suspension, fender clearance, or speedometer calibration.
Regional variations and care tips
Regional markets sometimes offer slightly different tire combinations due to supplier availability or regulations. Always check the car’s door jamb sticker or the owner’s manual for the exact specification on your vehicle. Regular tire maintenance—proper inflation, tread depth checks, and rotation—helps preserve performance and safety.
Summary
In summary, the GR Supra uses two main factory tire configurations: 18-inch wheels with 225/40R18 front and 255/40R18 rear, and 19-inch wheels with 255/40R19 front and 275/40R19 rear. Michelin Pilot Sport 4S tires are commonly specified, and exact sizes can vary by edition and market. Always verify the exact numbers on the vehicle if you’re unsure.
