What is the proper tire pressure for cars in hot weather?
1 Answers
In summer, the tire pressure for cars is generally between 2.2-2.4kPa. As the temperature of the air and road surface rises, the tire pressure can easily increase when driving at high speeds or over long distances. Each brand and model of car has a standard tire pressure range, which is usually indicated on a label attached to the vehicle. The location of this label varies by car brand. Some are placed on the B-pillar of the driver's door, some on the fuel tank cap, and others on the door frame of the passenger side. The label shows the corresponding tire pressure for each tire model, typically including the comfort pressure, half-load pressure, and full-load pressure. When inflating the tires, first check the tire model to find the corresponding pressure, then select the appropriate pressure based on the vehicle's load. For example, if the comfort pressure for all four tires is 2.4bar, in summer, it's sufficient to inflate them to 2.2bar. Inflating to 2.6bar would be slightly too high. It's advisable to choose a pressure that is 0.2bar lower than usual. This is because high summer temperatures cause the air inside the tires to expand. Conversely, in winter, it's appropriate to slightly increase the pressure, as cold temperatures cause the air inside the tires to contract.
