What is the recommended tire pressure for a 2021 Toyota Supra?

The 2021 Toyota Supra uses 32 PSI cold on the front axle and 36 PSI cold on the rear axle. These are the OEM specifications. Always measure tire pressure when the tires are cold — before driving or after sitting for at least 3 hours.

What tire size does the 2021 Toyota Supra use?

The standard (base trim) tire size for the 2021 Toyota Supra is 255/35R19. Higher trim levels and optional packages may use a different size — check the sticker inside your driver's door for the exact specification for your vehicle.

How do I convert the 2021 Toyota Supra tire pressure to bar?

32 PSI = 2.2 bar (front) and 36 PSI = 2.5 bar (rear). In kPa: 221 kPa front and 248 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures different on the 2021 Toyota Supra?

The 2021 Toyota Supra uses 32 PSI front and 36 PSI rear because the two axles carry different loads. The front axle carries roughly 48% of the vehicle's 1570 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.

What happens if the 2021 Toyota Supra tires are underinflated?

Running 5+ PSI low on the Toyota Supra causes uneven shoulder wear, increased rolling resistance (worse fuel economy), higher tire operating temperature, and reduced wet braking performance. In extreme cases, chronic underinflation can cause sidewall failure. Check pressure monthly and always after a large temperature swing.
