What is the normal tire pressure in winter?
2 Answers
In winter, the appropriate tire pressure for cars is between 2.2 and 2.4 bar. Car tire pressure refers to the air pressure inside the tire, and the level of tire pressure plays a significant role in the performance and power of the vehicle. The relevant introduction to tire pressure is as follows: 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 tire pressure requirements are more stringent. 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 influences the lifespan of the tire. Tire pressure selection: Tire pressure is an important factor affecting the service life and economy of the tire. Choosing an unreasonable tire pressure can lead to power cycle issues, thereby increasing tire wear and affecting service life. Considering the impact on power performance, it is essential to select the appropriate tire pressure to extend the tire's service life and improve economy.
After driving for so many winters, I find tire pressure adjustment quite crucial. The standard tire pressure for most cars is between 30 to 35 PSI, but don't apply it uniformly—it's best to check your car's manual or the label on the door frame. In winter, lower temperatures cause the air to contract, leading to slightly lower tire pressure compared to summer. I prefer checking it with a tire pressure gauge when the car is cold and topping it up to the recommended value. Too low tire pressure increases fuel consumption and tire wear, even risking a blowout, while too high reduces grip, affecting braking distance on icy or snowy roads. It's advisable to check once a month and pay extra attention when the weather turns cold, as it greatly benefits both safety and fuel efficiency. With good tire condition, driving feels more secure, and you don't need to worry too much about the indirect effects of low temperatures on tires.
