Tire Temperature, Rising When Tires Pressure Is Too Low
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Audi S6, 2018 Audi A6 Quattro, 2018 Audi A6, 2017 Audi S6, and 2017 Audi A6 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
The diagram shows the temperature behavior of a tire at 180 km/h (112 mph).
A - Normal range. When maintaining the specified tire pressure, the temperature remains stable
B - Danger zone. When the air pressure is 0.3 bar (4.35 psi) below specification, the temperature rises to above 120° C (32° F) at higher speeds
C - Critical temperature limit. The tire defect is triggered
T - Temperature
T - Driving time in minutes
