Is the tire pressure affected by the season?

In a blink of an eye, the weather is getting hotter and hotter, and it has entered summer. Many friends may have some questions: Do you want to deflate the tires in summer? What is the appropriate tire pressure in summer? Maybe many novice drivers don't know much about it, so today Bian Xiao will tell friends about this problem, hoping to help the car owners in summer.

Should the tires be deflated in summer?

If your cold tire pressure is higher than the standard tire pressure recommended by the manufacturer, you need to deflate it;

If your cold tire pressure is lower than the standard tire pressure, don't try to deflate it, but replenish it. In short, the principle is to maintain the standard tire pressure recommended by the manufacturer, and not to deliberately raise or lower it. Too high or too low tire pressure will have a negative impact on tires.

Just keep the standard tire pressure recommended by the manufacturer.

The manufacturer has the standard tire pressure recommended by the original factory.

As for the problem that high temperature will make the gas inside the tire expand with heat and contract with cold, the manufacturer has taken it into account when designing. The given normal tire pressure is also suitable for high temperature weather in summer, even at high speed.

Therefore, under daily driving conditions, even in hot summer, as long as the tires are inflated according to the manufacturer's regulations, there is no need to reduce the tire pressure by itself.

We usually talk about cold tire pressure.

Of course, it says cold tire pressure. Cold tire pressure is the tire pressure when the car is not driving. Hot tire pressure is the tire pressure after long-distance driving!

Our car owners and friends should remember that the tire pressure we usually say is cold tire pressure, not hot tire pressure. If it is hot tire pressure, the longer the driving distance, the faster the driving speed, the higher the tire pressure and the inaccurate tire pressure.

Where can I see the standard tire pressure recommended by automobile manufacturers?

Tire pressure refers to the pressure of air inside the tire, which is what we call tire pressure.

Every car has a standard tire pressure value, which can be seen in the general vehicle user manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, the small door of the fuel tank cover, etc.

The standard tire pressure recommended by different brands is different. I suggest that all car owners and friends keep this tire pressure value in mind. It is suggested that the average car should be between 2.2 and 2.5 bar, and SUV models should be between 2.3 and 3.0 bar.

This tire pressure gauge will generally display tire parameters, tire pressure of different tire widths under different loads, and our car owners can adjust the tire pressure according to the standard value according to the load of the car.

What are the hazards of abnormal tire pressure?

Tire pressure will be affected by driving conditions, driving time, tire temperature and weather temperature, so tire pressure is not a constant value.

Just like our weight, it is constantly changing. Being too fat or too thin will affect our physical condition.

Danger of high tire pressure: tire friction decreases, which affects braking; The automobile has poor shock absorption effect and low comfort; The wear of tread center pattern is large, which affects tire life; The vibration of the car body becomes larger, which affects the life of other parts; When encountering sharp objects, it is easy to plunge into the fetus, leading to internal cracking and blasting, resulting in puncture.

Harm of low tire pressure: the contact area with the road surface becomes larger and the fuel consumption increases; The steering wheel becomes heavier and easy to run off; Tire heating seriously damages tire life, promotes rubber aging, and the strength drops sharply; If the vehicle runs at high speed and the tire strength is not enough, it may lead to a puncture.

Too high or too low tire pressure will affect the service life of tires.

Wuhan University of Automobile Technology found that tire pressure is too high or too low, which is easy to cause puncture. Every time the tire pressure is lower than the standard value by 20%, the service life of the tire will be reduced by 30%, while if the tire pressure is too high, the deformable range of the tire will be reduced and it will be more vulnerable to mechanical damage.

How to measure the actual tire pressure?

If your car has tire pressure monitoring, you can observe the tire pressure value at any time to understand the tire health.

Fortunately, the national standard requires all passenger cars in production to be installed with TPMS (Tire Pressure Monitoring System) from June 65438+1 October1day, 2020.

If the car does not come with it, you can install or use a manual tire pressure monitoring tool in the future.

Bian Xiao's summary:

I suggest you check your tires more often, especially before you go to expressway. Tire pressure has a great influence on our driving safety.

The tire pressure should not be too high or too low, just refer to the recommended standard value of your car.
