The standard cold tire pressure for most 2013 Audi A4 models is typically around 32 psi for both front and rear tires, but the exact numbers depend on tire size and load; always check the driver’s door placard for the precise specification.
Where to find the official specification
To ensure accuracy, start with the car’s own documentation and label. The exact value depends on the tire size and the vehicle’s load configuration.
Door jamb placard
The placard on the driver’s door jamb lists the recommended cold pressures for front and rear tires, and sometimes the spare. It also shows the tire size the car was built with, which matters when matching pressures to tires.
Owner’s manual and tire sidewalls
The owner’s manual provides general guidance, and the tire sidewalls indicate the tire size and maximum inflation, which is not the operating pressure but useful when replacing tires or selecting a replacement. Use the placard for daily inflation targets.
To help you locate the official numbers and apply them correctly, use the steps below.
- Check the door jamb placard for the exact cold tire pressures (front and rear) specified for your model and tire size.
- Note the tire size printed on the sidewall of your tires and ensure it matches the size referenced on the placard.
- If you’ve installed aftermarket wheels or run-flat tires, verify whether the recommended pressures differ from the stock setup, and consult the manual or a dealer for confirmation.
In short, the placard provides the official numbers you should use whenever you inflate the tires cold.
Typical pressures by wheel size (general guide)
Beyond the placard, here is a general sense of how pressures may vary with wheel size. Exact numbers can differ by trim, tire model, and load, so always use the placard for final figures.
- 16–17 inch wheels (common base sizes): around 32 psi front and 32 psi rear.
- 18 inch wheels: commonly 33 psi front and 32 psi rear, or 34 psi front and 34 psi rear depending on load.
- 19 inch or larger wheels: pressures often in the mid-30s (for example 34–36 psi), but verify with the placard.
These ranges are approximate. The official numbers on the placard should be used for daily driving and varying loads.
Practical considerations
Seasonal and temperature effects
Tire pressures fall with colder temperatures. Check and adjust pressures when tires are cold—ideally before driving or after they’ve been parked unused for several hours. Temperature changes can cause noticeable pressure shifts, affecting handling and wear.
Load and driving conditions
Heavier loads or spirited driving can influence the preferred pressures within the placard’s recommended range. Do not exceed the maximum pressure printed on the tire sidewall and respect the vehicle’s specified range on the placard.
Summary
For a 2013 Audi A4, the recommended cold tire pressures are listed on the driver’s door jamb placard and typically sit around 32 psi for both front and rear tires on standard setups. Exact figures depend on tire size, model year specifics, and load, so always verify with the placard and consult the owner's manual if you’ve changed wheel sizes or tires. Regularly checking tire pressure helps with safety, fuel efficiency, and tire longevity.
