The quickest answer is to look at the driver’s door jamb placard for the official cold tire pressures, and to use the car’s Tire Pressure Monitoring System (TPMS) in the MMI to verify current readings. Inflate to the recommended targets when the tires are cold.
Where to find the official tire pressure recommendations
The official tire pressures for your Audi S5 are listed on a placard located on the driver’s door jamb. This placard shows the recommended cold inflation pressures for the front and rear tires, and it may differ if your vehicle has different wheel sizes or configurations. Always use these figures as your target when filling tires, and remember that they are specified for cold tires (before driving or after the car has been stationary for several hours).
- Open the driver’s door and inspect the placard on the door jamb or the edge of the door itself.
- Look for the lines that read something like “Tire inflation pressure” or “Cold tire pressure,” with separate values for Front and Rear tires.
- If your S5 uses a different wheel/tire size than stock, confirm the correct values in the owner’s manual or from an Audi dealer.
- Note that the placard reflects the recommended pressures for driving in standard conditions; do not rely on max sidewall pressure for daily inflation.
Carrying the correct pressures as indicated on the placard supports optimal handling, fuel efficiency, and tire longevity. If you switch to a non-stock tire size or pressure sensor configuration, always verify the numbers with official guidance.
Reading current pressure with the TPMS in the MMI
The Audi S5’s Tire Pressure Monitoring System (TPMS) provides real-time readings of each tire’s current pressure. Access to these readings is usually through the vehicle’s MMI system. The exact menu path can vary by model year and MMI version, but common routes include Car > Tyre Pressure or Vehicle > Tyre Pressure. Ensure the tires are cold when taking readings for a proper comparison to the placard values.
- Power on the MMI and navigate to the Tire Pressure screen via Car/Vehicle menus.
- View the pressure for each tire (and note any alert if a tire is below target).
- Compare the displayed pressures to the door jamb values; if a tire is low, inflate to the recommended cold pressure.
- If you’ve recently driven or the tires are hot, remember readings will be higher; recheck when the tires have cooled down.
TPMS is a helpful safety tool because it can alert you to slow leaks or punctures before you notice them by performance changes. If a TPMS warning persists after inflating to the recommended level, consult a technician to inspect for leaks or damage.
Additional context: understanding measurements and practical tips
Beyond the door placard and TPMS readings, keep a few practical points in mind to ensure accuracy and safety:
- Cold tires read the most accurate baseline pressure; check before you drive or after the car has been parked for several hours.
- The number printed on the tire sidewall is the maximum allowable pressure, not the recommended pressure for everyday driving.
- If you change wheels or tires from stock, verify the correct target pressures with the owner’s manual or your dealership, as recommended values can change with different tire sizes or load ratings.
In practice, combining the placard guidance with TPMS verification gives you the most reliable picture of your S5’s tire pressures. If you’re unsure about readings or notice a discrepancy between TPMS and the placard, have the tires inspected by a qualified technician.
Summary
For the Audi S5, the official tire pressures live on the driver’s door jamb placard and should be your target when tires are cold. Use the MMI TPMS to monitor current pressures, and inflate to the placard-recommended values when needed. Remember to account for tire heat, wheel size changes, and potential leaks by consulting a dealer or the owner’s manual if discrepancies arise.
