Is a tire pressure of 2.0 normal in winter? Do I need to add air?

[LeFrank]

A car with a tire pressure of 2.0 can drive normally, provided that the car is in an unloaded state. Below is relevant knowledge about car tires: The role of tires: Car tires are one of the important components of a vehicle. They directly contact the road surface and work together with the car's suspension to mitigate the impacts encountered during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The important role tires play in vehicles is increasingly being recognized. Classification of tires: Full-size spare tire: A full-size spare tire has the exact same specifications as the other four tires on the car and can replace any temporarily or permanently unusable tire. Compact spare tire: This type of spare tire has a slightly smaller diameter and width compared to the other four tires, so it can only be used as a temporary replacement and must be installed on non-driving wheels. Additionally, the maximum speed should not exceed 80 km/h.
