How to Check and Maintain the Tyre Pressure on Your Audi A8 Tyre Pressure

Cool Down: Ensure tyres are cold (driven less than 2 miles).
Unscrew: Remove the valve cap from the tyre valve.
Measure: Press your gauge onto the valve stem firmly.
Compare: Match reading to the table above or your door placard.
Adjust: Add air if low; release air if high (using the pin in the valve).
Cap: Replace the valve cap securely.

Understanding the Importance of Proper Tyre Pressure for Your Audi A8 Tyre Pressure

Maintaining the correct tyre pressure is essential for the longevity of your tyres and fuel efficiency. Under-inflated tyres can lead to overheating and premature failure, while over-inflation results in a harsh ride, reduced traction, and uneven tread wear.

Maintaining the Ideal Tyre Pressure for Your Audi A8 Tyre Pressure: Dos and Don'ts

Do check pressures when tyres are cold (driven less than 2 miles).
Do use a reliable gauge; gas station gauges can be inaccurate.
Don't bleed air from hot tyres; pressures naturally rise when driving.
Don't ignore the spare tyre check.

Winter vs. Summer Tyre Pressures

In winter, for the Audi A8 Tyre Pressure, consider adding 0.2 bar (3 PSI) to the standard pressures if you are using winter tyres, as cold air causes pressure to drop.

5-Point Tyre Safety Check

Pressure: Check all 4 tyres + spare monthly.
Condition: Look for cuts, bulges, or embedded objects.
Tread: Legal minimum is 1.6mm; recommended replacement at 3mm.
Valves: Ensure caps are tight to prevent dirt ingress.
Alignment: uneven wear indicates tracking issues.
