Can you deflate the tires in summer to prevent puncture?

The weather is hot, and riders with strong hands-on ability have begun to ponder over doing some heatstroke prevention and cooling work for their cars. It is easy to have a flat tire in summer, so it is essential to adjust the tire pressure. Recently, people have different views on whether the tire pressure should be raised or lowered in summer.

The traditional view is that when the temperature is high in summer, the tire pressure is definitely higher than that in winter, and it is easy to puncture when heated, so it should be lowered.

Another view is that if the tire pressure is reduced, the friction between the tire and the ground will increase exponentially, the tire temperature will rise sharply, the tire will become soft and the strength will drop sharply. In this case, if the vehicle runs at high speed, it may lead to a flat tire. Therefore, not only can the tire pressure not be lowered in summer, but it should also be raised.

So which statement is correct? The tire pressure should be low but not high.

Reducing tire pressure will bring two consequences. First, grinding tires will shorten the life of tires; Second, fuel consumption will increase. However, reducing tire pressure will reduce the risk of puncture. Due to the hot weather in summer, especially when driving at high speed, when the vehicle speed reaches 100~ 120 yards, the tread temperature will reach 80℃, even exceeding 100℃, and the internal pressure will increase.

As for increasing tire pressure, the only use is to reduce fuel consumption. However, increasing tire pressure will bring many unfavorable factors, such as increasing braking distance, which is not conducive to safe driving. Therefore, the principle of tire pressure in summer is that it can only fall, not rise.

The tire pressure value of automobile tires is generally 2.3~2.8BAR, as long as it is within this range, it is safe. However, the temperature is high in summer, and the tire pressure that was originally within the normal range may actually rise above 3.0BAR after the car is started, so in summer, we should take a lower tire pressure value within the normal tire pressure range, which is more appropriate between 2.3 and 2.5 bar.

If your car tire is old or injured, you should adjust the tire pressure to a lower level.

The standard tire pressure value is marked on each car.

Many novices are still confused: how much is my tire pressure normal? Where can I find it? In addition to the manual, every car will indicate the standard tire pressure value, but it will take some time. Most cars will be attached to the cab door; Some cars will go to the back door; There are also some cars marked on the fuel tank cover.

A. vehicle user manual;

B. Label next to the cab door (near the B-pillar);

C. the drawer next to the driver's seat of the vehicle;

D. fuel tank cover door;

E. The tire pressure of the car is near the doorpost or on the fuel tank cover, or look at the passenger door of your car. Different models have different weights and tires. Front wheels and rear wheels are generally different.

Be careful when measuring the tire pressure yourself.

Many car manuals indicate that the owner should check the tire pressure once a month.

What needs special reminder is that riders who like DIY tire pressure measurement should pay attention not to disturb the valve core, which will cause tire leakage after measurement-after tire pressure measurement in specialty store, the staff will help you check it to ensure that it will not leak.

Abnormal tire pressure is harmful:

Abnormal tire pressure causes uneven tire wear, which reduces driving comfort and is more related to driving safety.

1, tire pressure is too high:

A. The friction and adhesion of tires will be reduced, which will affect the braking effect;

B, steering wheel vibration deviation, reduce driving comfort;

C, accelerating the local wear of the central tread pattern of the tire and prolonging the service life of the tire;

D. The vibration of the car body becomes larger, which will indirectly affect the life of other parts;

E. The tire cord will be excessively stretched and deformed, and the elasticity of the carcass will decrease, which will increase the load when the car is running;

F. and reduce the rolling resistance. When you meet sharp objects such as nails and glass on the road, it is easy to plunge into the tire, and the impact will produce internal cracks and explosions, leading to a puncture.

2. The tire pressure is too low:

A. The friction coefficient with the road surface will increase and the fuel consumption will increase;

B factors that are not conducive to driving safety, such as overweight steering wheel and easy deviation;

C. Increase the amount of exercise in all parts of the tire. Excessive rolling will cause abnormal heating of the tire;

D, the function of cord and rubber is reduced, resulting in cord breakage and delamination or excessive friction between rims, resulting in tire bead damage and abnormal wear;

E. The friction between the tire and the ground is multiplied, the tire temperature rises sharply, the tire becomes soft, and the strength drops sharply. Vehicles driving at high speed may cause tire leakage;

F. Too low tire pressure will increase the deformation of the carcass, and cracks will easily appear on the sidewall. At the same time, it will cause excessive heating, promote rubber aging, tire cord fatigue, and cord breakage. It will also increase the tire contact area and accelerate the shoulder wear.

Nitrogen filling is of little significance.

In summer, many riders like to add some nitrogen to their tires. Their reason is that nitrogen is not easy to expand than air, and the safety factor is relatively high.

Although nitrogen is indeed superior to ordinary air, it is not necessary to force it. "The tire is not as delicate as you think, and the little tire pressure difference caused by nitrogen is completely within the tolerance range of the tire. In terms of safety, the psychological effect of nitrogen filling is greater than the actual effect, but the price is one or two hundred yuan more expensive than air filling. "

How to pre-tie tires;

Install air pressure monitor to accurately monitor tire pressure and tire temperature in real time.

A. Low-pressure alarm prompt: When the tire pressure of the automobile is lower than 1.7Bar, the tire pressure icon and number at the corresponding position of the display screen will flash and prompt, and at the same time a beep alarm prompt sound will be given;

B. High-pressure alarm prompt: When the automobile tire pressure is higher than 3.3Bar, the tire pressure icon and number at the corresponding position of the display screen will flash and prompt, and at the same time, a beep alarm prompt sound will be issued;

C. Quick air leakage alarm prompt: When the automobile tire is about to leak, the tire pressure icon and number at the corresponding position of the display screen will flash and prompt, and at the same time, a beep-beep-beep alarm prompt sound will be given;

D. High-temperature alarm prompt: When the tire temperature of the automobile is higher than 70℃, the tire pressure icon and number at the corresponding position of the display screen will flash and prompt, and at the same time, a beep alarm prompt sound will be issued;

E. low battery power prompt of sensor: when the battery power of sensor on automobile tire is low, the tire pressure icon and number at the corresponding position of the display screen will flash and prompt, and at the same time, it will give a beep alarm prompt sound. (Different brands have different alarm sounds. Now most new cars are equipped with tire pressure monitors. )

Flat tires are generally not paid.

Some car owners think that they have bought all insurance. In case of a flat tire, the insurance company will compensate them. In fact, tires are consumables and are often not included in compensation. Therefore, car owners should pay more attention to avoid personal and property losses caused by puncture accidents.
