Tire pressure, like a human weight, changes constantly “Too fat, too thin” can affect your “health” So keep it within the normal range

There are data showing When the fetal pressure value is higher than a quarter of the standard value The probability of traffic accidents has been doubled When the fetal pressure value is below a quarter of the standard value The probability of accidents will fold Thus, tire pressure is very important to driving safety

PART 1

Hazard of abnormal tire pressure

Tire pressure will be affected by driving road conditions, time, temperature, weather and other factors, and is not constant. Let’s talk about the dangers of abnormal tire pressure:

Increased fuel consumption

When the tire pressure is insufficient, the contact surface between the tire and the ground becomes larger, the tire resistance coefficient increases, and the fuel consumption increases in the process of driving. Related studies show that for every 10% reduction in the tire pressure, the fuel consumption increases by about 2%.

Tire life reduction

In terms of tire floor area, when the tire pressure is too high, the weight of the body will be concentrated on the center surface of the tire, and when the middle tire wear is insufficient, the tire force area increases, with heavy edge and light center, leading to the increased wear on both sides of the tire. Therefore, whether the tire pressure is too high or too low, it will lead to the reduction of the tire life, and even cause serious safety risks.

A flat tire is potentially dangerous

According to the analysis, 77% of the reasons for a vehicle tire burst are related to too high or insufficient tire pressure. Especially in the process of high speed driving, when the tire pressure is insufficient, the tire is in a state of high frequency deformation, the separation of the tire body, and the tire pressure, the tire body elasticity decreases, when the tire is more prone to tire burst.

The vehicle was unusually bumpy

When the tire pressure is insufficient, the adhesion decreases during driving, in the uneven road surface, when the tire pressure is too high, the vehicle fluctuation frequency is too high, the comfort will decrease.

The brake function is weakened

Tire pressure is too high, insufficient grip; tire pressure is too low, the contact area becomes larger. This will lead to the tire grip, which affects the braking effect, making the braking distance longer, easy to lead to vehicle rear-end.

PART 2

China’s mandatory national standard for tire pressure monitoring of passenger cars stipulates that from January 1,2020, all passenger cars in production will be forced to install TPMS (tire pressure monitoring system), and the important impact of tire pressure monitoring on driving safety can be seen. Therefore, we should pay attention to the tire pressure safety, we should understand the tire pressure monitoring system.

During driving, when the tire pressure alarm light is on, please immediately reduce the speed and find a safe place to stop. Check the vehicle tires (such as confirming whether the appearance and pressure are normal). If the alarm light is still not extinguished, please go to the repair point for repair in time. Here we would like to remind the majority of owners, if your vehicle has not installed tire pressure monitoring, please regularly check the tire pressure value, and timely install direct tire pressure monitoring system, tire pressure temperature value at a glance
