Because of thermal expansion and cold shrinkage, it is okay to keep the tire pressure of a car at 2.3 bar or even to 2.5 bar in winter, but the standard tire pressure specified by each car is different, so the specific requirements depend on the car's user manual, but the tire pressure in winter is 0.1 to 0.2 bar higher than the normal setting.
The tire pressure of the car must be maintained within the prescribed standard range. If it is too high or too low, it may cause problems in the driving of the car. For example, the tire pressure is too high, which will reduce the adhesion of the car tires, feel the vibration of the steering wheel, and affect the drainage and service life of the car tires.
If the tire pressure of the car is too low, the resistance during operation will increase, resulting in an increase in the fuel consumption of the car.It will also cause the car tires to become very soft and the friction will become greater. If we are driving at a fast speed, a flat tire may also occur, which will have a greater impact on the safety of the vehicle.
What should I pay attention to when using tires in winter？
1. First of all, we must check the car tires daily, because the temperature is relatively low, which may affect the hardness of the tires, causing the wear to be slightly more serious than in other seasons. Regular inspections can reduce the probability of accidents；
2. Because of icy roads and other conditions, there may be some ice ballast or stones stuck in the tire pattern. We must check in time, otherwise it may cause a flat tire；
3. We should pay attention to detecting the tire pressure of the car at any time. Once it is found to be too high or too low, we must take adjustment measures in time to avoid more serious situations.
