How often should car tire pressure be checked?
2 Answers
Car tire pressure should be checked once a month, and a tire pressure gauge can be used for measurement during routine checks. Before long-distance driving, the tire pressure of each tire should be checked individually, as both underinflation and overinflation pose safety risks. The standard tire pressure for each vehicle can be found on the back of the fuel filler cap, and it varies by car model. Generally, the standard tire pressure for family cars is 2.3 bar. Depending on the increase in load, the tire pressure can be appropriately increased. When the load is heavy, the front tire pressure can be adjusted to 2.4 bar, and the rear tire pressure can be adjusted to 2.6 bar. It is impossible for the tire pressure of each tire to be exactly the same, and a 0.1 bar deviation is allowed when measured under cold conditions. For example, one tire may be 2.4 bar while another is 2.5 bar, but a difference exceeding 0.1 bar may cause uneven tire wear.
As an ordinary car owner with over a decade of driving experience, I've accumulated quite a few practical tips. When it comes to checking tire pressure, I never take it lightly. Generally, I recommend checking at least once a month. Personally, I often choose to have it checked by gas station attendants during weekend fill-ups, or simply buy a basic tire pressure gauge for home use. Why be so diligent? Because both overinflation and underinflation cause problems: excessive pressure leads to faster wear in the tire center and unstable driving, while insufficient pressure increases fuel consumption and raises the risk of blowouts, especially during long highway trips. Many modern cars have tire pressure warning lights - never ignore them when they illuminate. I also pay attention to seasonal changes; for instance, tire pressure drops in winter when temperatures fall, requiring extra checks. Consistent monitoring extends tire life, enhances driving safety and comfort, and even saves on fuel costs - a win-win situation. Developing this habit is really no trouble at all.
