The official cold tire pressures for a 2019 Audi A4 are printed on the driver’s door jamb placard and are typically in the low-to-mid 30s psi (around 32–34 psi) for both front and rear tires. Always verify the exact figures for your vehicle and tire size.
Where to find the official specification
To locate the official tire pressure spec, check these sources:
Door jamb placard
The placard on the driver’s door edge lists cold tire pressures for the front and rear tires for your exact configuration and tire size.
- Location: On the edge of the driver's door or the door frame when the door is open.
- What it shows: The recommended cold pressures for front and rear tires.
- Notes: It may show separate values for different tire sizes if your car came with options; use the values that match your tires.
Reading the placard yields the official target numbers you should aim for when tires are cold.
Owner's manual and Tire Information
The owner's manual includes a Tire and Loading Information section that reiterates the recommended tire pressures and provides guidance for various loads and driving conditions.
- Where to find: In the manual, typically under "Maintenance" or by index search for Tire Pressure.
- What it adds: Guidance on inflation when carrying heavy loads, and notes about temperature effects.
- Symbols: It may reference the same numbers shown on the placard and explain how to adjust for different loads or weather.
Use the manual to cross-check the placard and to understand how pressure may shift with different loads or weather.
Typical ranges and variations
Even with a fixed placard value, several factors can influence the optimal pressure in daily use. Here are common considerations for the 2019 A4 with typical all-season tires on 17–19-inch wheels.
- Front tires: commonly in the low 30s psi, often around 32–34 psi when cold.
- Rear tires: usually similar to front, but some configurations call for slightly higher pressures under heavier loads or sport-oriented setups, e.g., 34–36 psi.
- Vehicle configuration: quattro all-wheel drive and sport packages may have different recommended rear pressures to balance handling and wear; always revert to the placard numbers for your car.
Understanding these variations helps you maintain safe handling and even tire wear without guessing.
How to check and adjust tire pressure safely
Maintaining correct tire pressure is essential for safety, efficiency, and tire longevity. Follow these steps to check and adjust your A4 tires correctly.
- Check when tires are cold: Park the car for at least three hours or drive less than a mile in the last three hours before checking.
- Find the target pressure: Use the front and rear numbers from the placard for your tire configuration.
- Use a reliable gauge: A digital or dial gauge gives accurate readings; remove the cap from the valve stem before checking.
- Adjust in small increments: If low, add air in 1–2 psi increments and recheck. If high, release air gradually until you reach the target.
- Re-check and reseal: After reaching the target, recheck all tires once more and reseal the valve caps.
Always re-check pressure after temperature changes or after driving to ensure you stay within spec.
Why PSI matters for your 2019 Audi A4
Correct tire pressure influences handling, braking, tire wear, ride comfort, and fuel economy. The A4’s balance, including its quattro system, responds to changes in tire pressure, so maintaining the manufacturer-recommended values helps preserve performance and safety.
Summary
The 2019 Audi A4’s tire pressure should be taken from the driver’s door jamb placard and the owner's manual, which typically place the recommended cold pressures in the low- to mid-30s psi. Confirm your exact figures for your tire size and load, and check pressures when tires are cold. Regular checks help safety, efficiency, and tire life.
