Tire inflation pressure is generally maintained at 2.2-2.5 bar, which is considered appropriate. In summer, it should be slightly lower. Effects of abnormal tire pressure: Excessive tire pressure reduces the friction and adhesion of the tires, increases the risk of tire blowouts, and affects driving safety. Insufficient tire pressure not only causes steering difficulties and vehicle deviation, which are detrimental to driving safety, but also damages the tires. Seasonal factors affecting tire pressure: In winter, it is advisable to increase the standard tire pressure by approximately 0.2 bar. In summer, follow the lower limit of the standard tire pressure. For vehicles parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to prevent high-temperature blowouts.

As a seasoned driver with years of experience, I've found that the proper tire pressure for sedans typically ranges between 30 to 35 PSI or 210 to 240 kPa, depending on the vehicle model and load conditions. The most reliable way is to check the label on the driver's door frame, which states the recommended values. Too low pressure increases the risk of a blowout and may cause loss of control during turns; too high pressure leads to faster wear in the center of the tire and a bumpy ride. I remember once driving with underinflated tires at 35 PSI—not only did fuel consumption skyrocket, but I nearly slid off a wet road. I recommend investing in a good tire pressure gauge and measuring it once a month when the tires are cold—that is, after the car has been parked overnight without driving. Weather changes also affect tire pressure; in winter, it drops significantly and needs topping up, while in summer, avoid exceeding the upper limit due to heat expansion. In short, keeping the pressure within the recommended range ensures both safety and cost savings.

When I first bought my car, I was completely clueless about tire pressure. A friend told me 30 to 35 PSI would do, but it turned out to be not that simple. After checking the manual, I learned that 30 PSI for the front tires and 32 PSI for the rear tires were ideal for my car, and I always made sure not to exceed the values specified in the manual when inflating. Too low pressure significantly increases fuel consumption—every 1 PSI drop raises fuel consumption by 1%; too high pressure causes severe shaking at high speeds. Through experience, I developed a routine: using a digital tire pressure gauge to check once a month, never trusting the outdated machines at gas stations. Seasonal changes matter a lot—pressure drops in cold weather, requiring inflation, while it naturally rises in hot weather, so avoid unnecessary adjustments. When carrying extra luggage, adding 2 to 3 PSI ensures stability. Now I understand that maintaining around 32 PSI is the safest bet—never skip the checks.

The standard tire pressure for sedans is generally around 32 PSI, which is the optimal value when the tires are cold. Use a reliable tire pressure gauge for measurement, ensuring the car has been stationary for a while to get an accurate reading. Overinflation accelerates wear in the center of the tire and reduces traction, while underinflation causes uneven wear on the tire shoulders and increases fuel consumption. Weather and road conditions also play a role—for example, you might need to add a bit of pressure in cold winter temperatures, and avoid overinflation in hot summer conditions. Adjust the pressure gradually, adding a little at a time and checking frequently. Remember, the vehicle manual or the label on the door is the ultimate reference—don’t rely on hearsay. Proper maintenance like this extends tire life and ensures driving safety.
