What is the recommended tire pressure for a 2019 Audi A4?

The 2019 Audi A4 uses 38 PSI cold on the front axle and 38 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 2019 Audi A4 use?

The standard (base trim) tire size for the 2019 Audi A4 is 245/45R17. 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 2019 Audi A4 tire pressure to bar?

38 PSI = 2.6 bar (front) and 38 PSI = 2.6 bar (rear). In kPa: 262 kPa front and 262 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures the same on the 2019 Audi A4?

The 2019 Audi A4 uses equal pressure front and rear (38 PSI). The vehicle's weight distribution and symmetric tire sizing mean both axles carry similar loads per tire.

What happens if the 2019 Audi A4 tires are underinflated?

Running 5+ PSI low on the Audi A4 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.
