What is the normal tire pressure for sedans in winter?
2 Answers
In winter, the appropriate tire pressure for cars is between 2.2 and 2.4 bar. Tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a crucial role in the performance and power of the vehicle. The following is a related introduction to tire pressure: Introduction to tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. Nowadays, many tires are not filled with air, and for these tires, the requirements for tire pressure are relatively strict. For tires filled with air, the pressure is related to seasonal changes. Moreover, tire pressure is closely linked to braking performance, affecting aspects such as comfort and load capacity, and it also impacts the lifespan of the tire. Choosing tire pressure: Tire pressure is an important factor affecting the service life and economy of tires. Improper selection of tire pressure can lead to power cycling, which in turn increases tire wear and affects service life. Considering the impact on vehicle dynamics, it is essential to choose the appropriate tire pressure to extend tire life and improve economy.
After driving for so many years, I think winter car tire pressure deserves more attention. The general normal range is around 32 to 35 psi, but it varies for each car, so it's best to check the owner's manual or the sticker on the inside of the door. My habit is to keep the tire pressure slightly higher in winter than in summer because the cold temperature causes the air to contract, naturally reducing the tire pressure. If you inflate the tires yourself, I recommend using a reliable tire pressure gauge to check after the car has been parked overnight for accurate readings. If not adjusted properly, it can lead to skidding, which is dangerous on icy or snowy roads, and also wastes fuel. My neighbor Lao Li learned this the hard way—his tire pressure was too low, causing a blowout, and he spent a lot on repairs. For safety, check the tire pressure at least once a month; it only takes a few minutes. The key point is not to overlook changes—small details can turn into big problems.
