What does the tire pressure marking on motor vehicle tires indicate?

The tire pressure marking on motor vehicle tires indicates the maximum tire pressure limit that the vehicle's tires should not exceed, for example, usually not exceeding 340kpa, which is equivalent to 3.4bar. Generally, the tire pressure marking on motor vehicle tires is located on the sidewall of the tire. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Methods for tire maintenance include: 1. Moving tires indoors during rain to prevent water ingress; 2. Avoiding areas that may cause tire damage or deformation; 3. Not placing tires near generators, batteries, etc.
The tire pressure marking indicates the recommended inflation pressure for the tires, usually measured in PSI or bar. I learned this from an experienced driver friend who said to always check the tires before driving. The markings are typically printed on the door frame or inside the fuel filler cap, showing the correct pressure for both front and rear tires. The most accurate reading is taken when the tires are cold, meaning before the car has been driven and the tires are at normal temperature. This is crucial because overinflation leads to faster tire wear and a less comfortable ride, while underinflation increases fuel consumption, lengthens braking distance, and makes driving unstable. I remind myself to check monthly with a simple tire pressure gauge. In summer, heat can cause pressure to rise, while in winter it tends to drop, so timely adjustments are necessary. This is a vital safety detail that must not be neglected, especially for new drivers—don’t dismiss it as trivial, as neglecting it could lead to regrettable consequences.
