Maintenance (Tire Air Pressure): Notes
WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
The weight of the vehicle flattens the tire's contact patch. When the tire rolls, this results in deformation all around the circumference of the tread and the entire belt assembly. With low pressure, there is a greater deformation which results in more intense warming and greater rolling resistance. This all results in a greater wear and a greater safety risk.
Example: specified series production tire pressure depending on load on cold tires
| Air Pressure in bar (psi) | Air Pressure (%) | Service Life (%) |
|---|---|---|
| 2.3 (33.36) | 100 | 100 |
| 1.9 (27.56) | 80 | 85 |
| 1.4 (20.3) | 60 | 60 |
| 1.0 (14.5) | 40 | 25 |
Excessive air pressure leads to greater wear at the center of the tire and reduced rolling comfort. It is recommended always to maintain the air pressure indicated by the manufacturer.
