What is the tire pressure under the normal load of different types of car tires? 80

Generally left and right is fine.

Air pressure is the lifeline of a tire, and too much and too low will shorten the life of the tire. If the air pressure is too low, the deformation of the carcass will increase, the sidewall is prone to cracks, and at the same time, it will produce flexural motion, resulting in excessive heating, promoting rubber aging, cord layer fatigue, cord breakage, and will also increase the tire grounding area and accelerate shoulder wear. If the air pressure is too high, the tire cord will be subjected to excessive stretch deformation, the elasticity of the carcass will decrease, and the load on the car will increase during driving, and the impact will produce internal cracks and bursts, and at the same time, the high air pressure will also accelerate the wear of the tire crown, and reduce the rolling resistance.

Fainted, there are too many models. This is marked on the sidewall of the tire, if you want to overload, for every 1% increase in load capacity, you need to play 2% more air pressure, but the overload is best not to exceed 10%.

Keep the air pressure value marked on the wall of each tire, that is, the most suitable pressure for the tire, which is a standard in the tire industry, to the air pressure value of the tire in kilograms square centimeters, pascals or pounds square inches (psi) marked on the tire wall, regular tire products have, from automobiles, motorcycles to bicycle tires without exception, at the same time, the size and installation direction need to be marked, some professional tires also need to indicate the rubber hardness.

To see the maximum total mass of the vehicle, the general approximate can also refer to the original tire pressure standard, the original tire pressure standard plate on the inside of the fuel tank cap.

The standard tire pressure for a car is set according to the make and model of the vehicle.

In the left and right. Tires are an important factor for the safe driving of cars, and tire pressure is to maintain the life of tires, so standard tire pressure is extremely important. Many people have a vague concept of tire pressure, unless there is a leak or a broken tire, otherwise they will not care how much tire pressure is played.

Generally, the tire pressure of ordinary cars can be controlled around the right, but the standards of different models are not the same, the specific need to control the tire pressure in what range, please refer to the car user manual or the door and other position of the label, pay attention to the tire pressure is a good habit, but there is no need to fidget for the tire pressure difference, if the car is not equipped with tire pressure monitoring, prepare a tire pressure gauge or install tire pressure detection can be more timely to understand the tire pressure. In summer, the normal tire pressure of the car needs to be lowered, because the temperature is relatively high when driving in summer, and the tire temperature of the car will also increase during the driving process, and the tire pressure will also increase, so in the summer, the tire pressure should be lowered to the point; On the contrary, in winter, because the temperature is relatively low, the tire pressure should be higher than the normal value. Dangers of low tire pressure:

When depressed, the tires are soft, and when they are driven, they deform more. Each part of the tire will come into contact with the ground once it turns, and the lower the tire pressure, the longer it will take for the deformation to recover. In other words, the lower the tire pressure, the faster it drives, the more likely it is to produce standing waves.

This phenomenon causes the temperature of the tires to rise rapidly, and the result is a puncture. 1. The friction coefficient with the road surface will increase, and the fuel consumption will increase. 2. The friction between the wheel potato tire and the ground increases exponentially, the tire temperature rises sharply, the tire becomes softer, the strength decreases sharply, and the vehicle travels at high speed, which may lead to a puncture.

3. If the tire pressure is too low, the deformation of the carcass will increase, and the sidewall will be prone to cracks, and at the same time, there will be flexural movement, resulting in excessive heating, promoting rubber aging, cord fatigue, cord breakage, and increasing the tire grounding area and accelerating shoulder wear. 4. Make the steering wheel of the vehicle heavier, easy to deviate, worse handling and greater tire noise. Dangers of high tire pressure:

When the tire pressure increases, the tire becomes stiffer, the effective ground area is reduced, and the rolling resistance is reduced accordingly, so it is fuel-efficient. But don't forget, the braking effect when braking is also directly related to this ground contact area. There are pros and cons, a few liters of gasoline are only a few dozen yuan, and if you can't stop it, it's a big deal.

1. The friction and adhesion of the tire will be reduced, which will affect the braking effect. 2. It leads to steering wheel shaking, deviation, and reduced driving comfort. 3. Accelerate the local wear of the tread pattern of the tire, which can easily lead to tire bulging and stones.

4. The tire cord will be subjected to excessive stretching and deformation, and the elasticity of the carcass will decrease, so that the impact of the car during driving will increase, and the driving noise will increase. 5. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate into the tire, and the impact will produce internal cracks and cause punctures. Edge.

For common cars, the tire pressure is within the normal range, which means that the tire pressure of the car is generally within this range to be appropriate. Of course, this is only the normal range of tire pressure for more common cars, and the specific value should be based on the tire pressure value recommended by the manufacturer. Generally available in the vehicle owner's manual; Label next to the cab door (near the B-pillar); drawers next to the driver's seat of the vehicle; fuel tank cover door; near the door pillar or fuel tank cover; Find the manufacturer's recommended tire pressure on the side of the passenger door.

Maintaining normal tire pressure is the key to ensuring the normal performance of the car, and too high or too low tire pressure will affect the tire and driving safety.

When the tire pressure is too high, it will reduce the adhesion of the tire, affect the braking effect, and the driver can feel the vibration of the steering wheel, and even make the car deviate in serious cases, reducing the comfort of driving. Because the tire pressure is too high, it will lead to a reduction in the contact area between the tire and the ground, increase the local wear of the tire pattern, and reduce the service life of the tire.

When the tire pressure is too low, the contact area between the tire and the ground will be increased, the friction coefficient between the tire and the ground will increase, the driving resistance will increase, the tire wear will be accelerated, and the service life of the tire will be reduced.

Moreover, the tire pressure is too low, which will increase the amount of movement of each part of the tire, and excessive crushing, which will cause abnormal heating of the tire, reduce the function of the cord and rubber, cause delamination or cord breakage, and excessive friction between the rim will cause damage to the bead part, and abnormal wear will occur in the morning.

However, it should be noted that the spare tire is not often used, and the air pressure of the spare tire should be higher, so as not to lose the emergency effect due to low air pressure when needed.

1. The normal tire pressure of the wheels of the general family car is one atmosphere, the general front wheel is one atmosphere, and the rear wheel is one atmosphere. 2. Check the location of the standard tire pressure in the car: the vehicle user manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the Lao Kai vehicle or the small door of the fuel tank cover.

The tires of the car are pressed near the door pillars, on the fuel tank cover, or on the side of the passenger door. 3. Normal tire pressure of wheels in different seasons: winter:

Based on the principle of the standard air pressure of the car wheel shed tire, the bar should be appropriately raised. Summer: according to the lower limit of the standard air pressure of automobile tires.

In summer, the car is parked in the open air, and the air pressure can generally be 0 lower than the standardAbout 1 bar to avoid punctures in high temperatures. Most of this can be found on a certain nameplate of the vehicle, some on the B-pillar, and some on the inside of the fuel tank cap.

The normal tire pressure is about one atmosphere. @2019

The standard air pressure for a car is. Nowadays, all kinds of cars, in the upper part of the user manual will indicate the tire pressure requirements of the car, and the first allowable deviation is the upper and lower kilogram pressure (one or two hundred kilopascal units).

Dangers of high tire pressure:

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

b.It causes the steering wheel to vibrate, deviate, and reduce the comfort of driving with the hand;

c.The pattern of the tire tread ** is partially worn to make the tire life down;

d.The vibration of the body becomes larger, which indirectly affects the life of other parts;

e.The tire cord will be subjected to excessive stretch deformation, and the elasticity of the carcass will decrease, so that the load of the car will increase during driving;

f.And the rolling resistance decreases. When encountering sharp objects such as nails and glass on the road, it is easy to penetrate into the tire, and the impact will produce internal cracks and bursts, resulting in a puncture.

According to the provisions and requirements of the international GBT2978-2008 standard:

1. Standard tires:

2. Reinforced tires:

3. Maximum air pressure: should not be greater than.
