Under what conditions should tire inflation pressure be checked to ensure a correct reading?

Question

DentroTest · Accepted Answer

Pressure must be checked only when the tires are cold. This is because, during driving, friction between the rubber and the asphalt generates heat, causing the air inside the tire to expand and temporarily increase the pressure. Important details: What is considered cold?: When the vehicle has been stationary for at least an hour or has been driven less than 2 or 3 kilometers at low speed. Common mistake: If you measure pressure when hot, you will get a higher reading. If you release air at that moment to match the manufacturer's recommendation, the tire will be under-inflated once it cools down, compromising stability and increasing fuel consumption. Frequency: It is recommended to check pressure once or twice a month and always before a long trip, not forgetting the spare tire.
