When should the inflation pressure of a bus's tires be properly checked?

Question

DentroTest · Accepted Answer

Tire inflation pressure must always be checked cold, that is, before setting off or after a very short trip. While driving, friction and deformation of the tire generate heat, which makes the air inside rise in temperature and expand, artificially raising the gauge reading. If the pressure is measured hot, it will read more than it should, and if the mistake is made of deflating the wheel to adjust the figure, the tire will end up running at insufficient pressure once it cools down, compromising stability and braking and increasing the risk of a blowout from overheating. On the other hand, you must not wait for the tires to look visibly deflated, since pressure loss occurs slowly and gradually, requiring regular and systematic checks.
