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 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. 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
