Maintenance (Tire Air Pressure): Notes
WARNING: This page is about a different car, the 2022 Audi SQ7 and 2022 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.
The vehicle weight causes a flattening on the tire contact area. When the tires roll, this produces pressure deformations all around the running surfaces and on the entire belt assembly. Low pressure produces higher pressure deformations causing a stronger heat effect and a greater roll resistance. This results in greater wear and a higher safety risk.
Example: specified standard pressure on cold tires depending on load capacity.
| Air Pressure (bar) | Air Pressure (%) | Mileage (%) |
|---|---|---|
| 2.3 bar (33.35 psi) | 100 | 100 |
| 1.9 bar (27.55 psi) | 80 | 85 |
| 1.4 bar (20.30 psi) | 60 | 60 |
| 1.0 bar (14.5 psi) | 40 | 25 |
An air pressure that is too high causes increased center wear and poor driving comfort. We recommend to always maintain the air pressure specified by the manufacturer.
