What is the recommended tire pressure for a 2023 Mercedes-Benz EQS?

The 2023 Mercedes-Benz EQS uses 42 PSI cold on the front axle and 44 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 2023 Mercedes-Benz EQS use?

The standard (base trim) tire size for the 2023 Mercedes-Benz EQS is 265/40R21. 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 2023 Mercedes-Benz EQS tire pressure to bar?

42 PSI = 2.9 bar (front) and 44 PSI = 3.0 bar (rear). In kPa: 290 kPa front and 303 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures different on the 2023 Mercedes-Benz EQS?

The 2023 Mercedes-Benz EQS uses 42 PSI front and 44 PSI rear because the two axles carry different loads. The front axle carries roughly 50% of the vehicle's 2480 kg curb weight, requiring a slightly different pressure to maintain the correct contact patch at each corner.

What happens if the 2023 Mercedes-Benz EQS tires are underinflated?

Running 5+ PSI low on the Mercedes-Benz EQS 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.
