Summer has arrived, and more and more people are concerned about tire pressure, because there are more cases of tire blowouts in summer than in other seasons, and abnormal tire pressure is a major factor causing tire blowouts. It is normal for summer tire pressure to fluctuate greatly. As long as the standard tire pressure is filled, we do not need to worry about any fluctuations. Do not run for a while to see the tire pressure rise, and then get off the car to deflate.
There is no need to deflate, raising it slightly does not affect it. When the tire cools down, it will naturally drop back to normal. There is no need to deliberately lower the tire pressure. The manufacturer recommends charging as much as possible, and the increase in high temperature does not affect the pressure. Some people are not only concerned about the high or low tire pressure, but also about the difference in tire pressure. Many times, the tire pressure of the four wheels is not the same. So, is there a significant impact of tire pressure difference? What are the hidden dangers? How much difference is considered normal?
It is normal to have a tire pressure difference, even if all four wheels are filled with the same tire pressure, there will be a slight difference after driving for a period of time, which has no effect. Generally speaking, controlling the difference in tire pressure at 0.1 bar will not have any impact. There are 2.3 and 2.4, so there is no need to worry about it. There are individual cases where the difference can be 0.2 bar. Some cars may have problems, while others may not. The biggest problem can cause deviation, especially when there is a large difference between the front wheels, which can lead to deviation towards the side with low tire pressure. Therefore, if the car suddenly deviates while driving normally, it is necessary to first check the tire pressure, which is basic maintenance knowledge. The difference in tire pressure is large, and over time, tire wear will also be uneven, which will exacerbate the deviation. Therefore, if the difference is above 0.2 bar, it needs to be adjusted.
The comparison of tire pressure mainly involves comparing the left and right wheels. When comparing two front or two rear wheels, the difference in tire pressure between the front and rear wheels can be slightly larger without any impact. Some car models have inconsistent standard tire pressures on the front and rear wheels, with the rear wheels being slightly higher, so left and right wheels need to be compared. No matter how large the tire pressure difference is, the tire pressure of a single wheel must be close to the standard tire pressure. The standard tire pressure cannot be 2.3, and each wheel should be charged to 3.0. Although all four wheels are the same, the tire pressure is too high and does not meet the standard. The standard tire pressure is the most reasonable for this car, which can ensure both economy and sufficient grip and braking distance.
To check tire pressure, it is generally necessary to cool the vehicle. The standard tire pressure marked on the fuel tank cap is the pressure of the cold tire. If you run at high speed for tens of kilometers, the tire pressure will increase by about 0.2 bar, and the measured air pressure is not standard. If the tire pressure just reaches the standard tire pressure at this time, it will definitely fall below the standard after the tire cools down, which means the tire pressure is insufficient. If driving at high speed for a period of time above the standard tire pressure of 0.2 bar, it is completely normal. Of course, driving at low speeds for more than ten kilometers in the city does not have a significant impact on tire pressure, so it is better to charge according to standard tire pressure. The pressure range that tires can withstand is very large, so there is no need to worry too much about tire pressure. Compared to standard tire pressure, a little higher or lower is normal. Generally speaking, in a cold car state, if it is below the standard 0.2 bar, it should be inflated, and if it is above 0.2 bar, it should be deflated.
