Under what temperature conditions must the inflation pressure of a bus's tires be checked?

Question

DentroTest · Accepted Answer

Tire pressure must be checked with the outer tires cold, preferably before setting off or after having covered very little distance. When rolling, friction raises the internal temperature of the tire, which expands the air and artificially increases the pressure. If it is checked hot, the gauge will show a value higher than the real one, and deflating a hot tire to adjust it would make it run with too low a pressure once it cools. On the other hand, relying only on visual appearance is a mistake: a significant loss of pressure may not be noticeable to the naked eye.
