Tires as the only parts of the car in contact with the ground, the performance of the vehicle is determined to some extent by the tire, and the tire's slightly out of the small situation may lead to a vicious accident, so the tire is very important! In the daily car, always pay attention to clean tire debris and maintain good tire pressure to help reduce the occurrence of invisible accidents, how much gas should the tire be inflated?
Many people, even if they are driving models with tire pressure monitoring, do not know how much the normal tire pressure value is, unless it is the tire pressure monitoring alarm, and usually rarely observe the tire situation. In general, how many tires to pump (standard tire pressure), experienced repair teachers will tell you that about 2.5 pounds, that is, 2.5-3.0bar.
In fact, this is not right, different models of volume, load and use are different, tire pressure must be different, so in accordance with the standard tire pressure of the vehicle to inflate. The value of the standard tire pressure can be found on the car. Each car will have a small label showing the value of the standard tire pressure. This small label usually appears in the vehicle owner's manual, next to the cab door (near the B-pillar), in the drawer next to the driver's seat of the vehicle, or in the small door of the fuel tank cap.
What is the effect of tire pressure not being in the standard value
Excessive tire pressure
The most intuitive feeling of high tire pressure is to affect comfort, just like riding a bicycle when you were a child, too much tire inflation will become hard, the car is very bumpy, and the car is the same. In addition, due to the excessive inflation of the wheel, the road is missing the buffer of the tire and is directly transmitted to the chassis, and the impact is completely alleviated by the shock absorber, accelerating the aging of the chassis.
When driving, because the tire is very heated by ground friction, the gas inside the tire will also expand, especially in the summer, the excessive pressure in the tire is easy to lead to tire deformation, the elastic strength of the tire body will be reduced, and the road impact and body load are more likely to cause the occurrence of tire blowout.
Tire pressure is too low
When the tire pressure is insufficient, the contact area between the tire and the ground will increase, increasing the friction force and resulting in higher fuel consumption. When the tire pressure is low, the tire will become softer, which does increase comfort, but the handling performance is poor, because the tire wall due to the lack of gas support, the left and right movement is increased.
Because the vast majority of vehicles are using tubeless radial tires, due to the increase of friction when driving in the loss of air, the tire heat will be serious, in addition to the steel wire in the tire body will friction with each other, accelerating the deformation of the tire and the decline in the strength of the steel wire, and too low tire pressure will also make the weakest part of the tire wall and the road contact, these are the root of the tire burst.
What's the danger of a flat tire
Tire pressure is too low or too high will cause a burst tire phenomenon, and the consequences of a burst tire are often very serious, high-speed vehicles encounter a burst tire will be out of control or even turn over, there are data show that when the vehicle speed exceeds 120 km/h, if the vehicle suffered a front tire burst mortality is almost 100%.
