We don't pay much attention to the time, but when we buy a new watch, we can't help but check it from time to time. The same goes for tire pressure monitoring. For models without tire pressure monitoring, the longest tire pressure check interval is usually recommended to be no more than three months, but it would be better to check it more frequently once a month. In certain cases, if you encounter sudden changes in temperature or other abnormal conditions, you should check the tire pressure as soon as possible. Tire pressure, a seemingly insignificant detail, is actually related to the safety of every trip.
First, we need to understand what factors may affect the tire pressure. The normal rate of loss of tire pressure is 0078, which is a number that cannot be ignored. Tires are like the shoes of a car, and the tire pressure is the "air cushion" of the shoes. If the air cushion is insufficient, the shoe will not provide adequate support and protection for the foot. Studies by well-known brands such as Michelin have shown that the normal rate of tire pressure loss is 0078。This means that if you don't check your tire pressure for a long time, your tires may gradually lose their support due to air leaks, increasing the risk of a puncture.
Secondly, changes in temperature can also have a significant impact on tire pressure. The relationship between tire pressure and temperature can be explained by a formula pv=nrt. where P represents the absolute pressure value inside the tire, V represents the volume of gas inside the tire, N is the amount of substance, R is the gas constant, and T is the temperature of the gas inside the tire. This formula tells us that the tire pressure changes with the temperature. For example, in winter, when the temperature plummets, if the tire pressure is not adjusted in time, the tire may lose its grip due to the low air pressure, leading to safety problems such as pulley.
In addition, the speed of the vehicle also has an impact on the tire pressure. A master's degree** from Yanshan University studied the temperature and pressure characteristics of tires under multiple operating conditions. In the test, when the ambient temperature is 15°C and the tires are working at a speed of 60kmh, the temperature rises by about 35°C. This means that at high speeds, the internal pressure of the tires increases due to friction heat. If the tire pressure is too high, it may increase the risk of a puncture.
Once we know what factors are related to tire pressure, we can determine how often to check tire pressure based on these factors. In general, checking tire pressure every three months is considered a minimum. However, considering the safety and longevity of tires, many tire manufacturers recommend a higher frequency of inspections than this standard. For example, both Michelin and Bridgestone recommend monthly check-ups, while Continental recommends a shorter period of 14 days.
In addition to regular tire pressure checks, real-time tire pressure monitoring systems are also an effective means to improve driving safety. The system monitors the tire pressure and temperature in real time, and if an abnormality is detected, an alarm is issued in time to remind the driver to take appropriate action. For vehicles that do not have a real-time tire pressure monitoring system installed, it is recommended that owners with conditions install one. This kind of system is not expensive, and it is easy to install, which can provide a strong guarantee for driving safety.
Of course, when choosing a tire pressure monitoring system, car owners need to choose according to their needs and budget. External** is relatively affordable, but may be less durable and carries a risk of theft; The built-in type is slightly higher, but more accurate, durable, and less susceptible to theft. For older cars without tire pressure monitoring, it is recommended that the maximum inspection period should not exceed three months, and it is best to check once a month if possible.
