Why do maintenance workers like to charge tires with 2.5 tire pressures, the 10-year-old master will tell you the truth
Are you curious about why, whether it's a luxury car or an economy car, the pit master always likes to inflate the tires to 2.5 bar? There is actually a little secret in the industry behind this. The standard tyre pressure for most vehicles is between 2.2 bar and 2.8 bar, and 2.5 bar is right in the middle of this range and can be adapted to most models. In addition, due to the physical characteristics of thermal expansion and contraction, the tires of the vehicle will become hot during driving, causing the actual tire pressure to rise. As a result, charging up to 2.5 bar ensures that the tire pressure remains within a relatively safe range, even after long periods of high-speed driving.
Knowing that 2.5 bar is a median value, which is both convenient and practical, let's take a look at what it is. There are actually several other interesting considerations for the masters. First of all, this number is easy to remember and quick to operate, which can greatly improve the efficiency of busy workshops. Imagine how time-consuming it would be if each car had to check the specific standards! And there are so many models, the standards are different, who remembers the masters!
Besides, when the car arrives at the repair shop, the tires are already hot, and the tire pressure is already high at this time. If you inflate it according to the standard of a cold car, it is likely to be overcharged. Therefore, even if the standard is 2.2 bar or 2.8 bar, charging up to 2.5 bar can ensure safety and performance in most cases, avoiding the trouble caused by improper inflation.
And, you know what? Tire pressure can have a big impact on a vehicle. The tire pressure is too high or too low, and the contact area between the tire and the ground is reduced, although the fuel consumption will be reduced, and it is a lot lighter, but the grip will decrease, and the safety will be hidden. If the tire pressure is too low, although the grip is good, the sidewall of the tire will be under a lot of pressure, easy to overheat, and even have the risk of a puncture.
Therefore, as a car owner, you must also know a little bit about this knowledge. You have to know what the standard tire pressure is for your car. Don't rely solely on the pits, after all, no one wants to have an accident because of a tyre pressure problem. If your car is special, or you have specific driving habits, such as often full loads or walking on mountain roads, you may need to adjust the tire pressure according to the actual situation.
Sometimes, you have to pay attention to adjusting the tire pressure when the seasons change. For example, in winter, when the temperature is low, the tire pressure will naturally decrease. At this time, if you do not increase some tire pressure appropriately, it may affect the performance and safety of the vehicle. On the contrary, when the temperature is high in summer, the tire pressure will naturally rise, and it may be necessary to reduce the tire pressure appropriately.
Don't look at this tire pressure is a small matter, but it is quite knowledgeable. Inflating is not a casual thing, and it has to be adjusted according to the actual situation of the vehicle and the external environment. It's not just for the performance of the vehicle, it's for our own safety.
Seeing this, do you also think that the next time you go to repair the car, should you also have a good chat with the master to see if the tire pressure of your car is set correctly? After all, whether the car is good or not, whether it is safe to drive safely, and the tire pressure can be a big deal. And we, as car owners, naturally pay more attention, don't underestimate the breath of this tire, it is related to our driving safety!
