What is the appropriate tire pressure? What is the right tire pressure for running at high speed?

In winter, when running at high speed and in a cold state, the tire pressure is basically around the right.

1. Running fast, because the tires have been rolling fast, they are hot, and there will be more air, that is, the tire pressure will be correspondingly higher, so the tire pressure should not be too high; 2. However, the tire pressure should try to ensure a principle of higher than low.

Generally speaking, the tire pressure is not the same for different tires. The tire pressure of standard tires is generally in between; Reinforced tires generally have tire pressures in between; But no matter how good your tires are, don't exceed them, otherwise there will be a puncture.

If you run at high speed, you can generally keep the tire pressure left and right, but when you run at high speed, the tire pressure can be based on the recommended value given by the manufacturer, and you can usually see the marking table near the vehicle owner's manual or door (B-pillar or C-pillar), as shown in the following figure:

Novices run at high speeds, and how much the car tires are pressed to be safe, depending on how the old driver does it.

What is the standard tire pressure when a car is running at high speeds? The old driver demonstrates to you that it can effectively prevent punctures.

Generally, the tire pressure value is normal between them. If the seat is full (5 people), it is more suitable to adjust the tire pressure to the left and right; Generally, if there are two people, the tire pressure value is also normal.

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

Standard tires:.

Reinforced tires:.

Maximum air pressure: should not be greater than.

When driving in the city, the air pressure is pumped according to the requirements of the original car, and the air pressure is higher than the usual air pressure in the city at high speeds, so it is enough.

The reason is that the tire is deformed once every time it turns on the ground, and the frequency of deformation at high speed is higher, so the deformation produces more heat, so that the tire temperature and air pressure are increased too much, and the air pressure is high, and the frequency of each deformation does not change but the amplitude becomes smaller, so the temperature and air pressure increase a little less when driving, which is beneficial to safety. The tire pressure value of car tires is generally safe, as long as it is within this range. However, in the summer, when the temperature is high, the tire pressure, which is within the normal range, may actually rise to above when the car is started.

Therefore, in summer, it is more appropriate to take a low tire pressure value within the normal tire pressure range.

In fact, in addition to the manual, the standard tire pressure value will be indicated on each car, and most riders do not pay attention to the place marked by this tire pressure value. This one will take some time to find out. Most cars are attached to the cab door, others are on the rear door, and some are marked inside the fuel tank cap.

Hello! Proper tire pressure is the most important part of tire maintenance. The standard tire pressure of the tire depends on the vehicle on which it is installed - that is, the tire pressure marked on the vehicle door or fuel tank cover, which is the standard value determined by the vehicle manufacturer in the design and manufacture to give full play to the best performance of the vehicle, and the difference is generally allowed to be within 10%, if it is lower than the standard value of more than 10%, it is a state of lack of air; If it is less than 20% of the standard value, you should go to a specialist shop as soon as possible to check the cause - whether there is any damage or air leakage.

The tire pressure should be measured when the tire is cooled - that is, before leaving the car, and the valve cap should be tightened after the tire pressure is measured. Generally speaking, the tire pressure will decrease by about one month on average; Temperature also has an effect on tire pressure, which usually rises and falls by 10°C.

It is not necessary to turn the tire pressure up in the winter, but it is important not to turn it down in the summer.

When driving at high speed for long distances (especially in hot summer), you can appropriately increase the tire pressure ( to reduce flexion heat generation and avoid punctures.

When driving in bad road conditions, the air pressure can also be increased appropriately (to reduce tire damage.

The correct way is to hit the standard tire pressure marked by the OEM regardless of whether it is cold or hot, in winter or summer. Because the tires have traveled more than 5 kilometers, the temperature will be 70 to 80 degrees, far more than the change in air temperature. The main engine factory has long considered it, so on the highway, the tire pressure is still your usual tire pressure value, it is best to follow the reference number of the car sufficient air pressure, and most owners ignore this detail.

Although it is relatively simple and crude, it can be convenient and trouble-free, and generally it will not cause major problems. The normal tire pressure for most wheels is around this value. If the tire pressure is lower, there is a problem, it is basically a loss of gas, and the tire will go down.

Hurry up and find a place.

<> dangerous. Note that the tire pressure is slightly higher, but it must not be too low, in fact, most of the tire blowouts are caused by low tire pressure, because the tire pressure is too low when driving, the contact area of the tread increases, which means that the side pressure on the shoulder is greater, the car runs at high speed and the general air pressure is around the right, if the air pressure is too high to more than 100 horsepower, it will run or shake, some do not understand the division machine running at high speed will generally go to the repair shop to measure the air pressure, four tires to keep the air pressure balanced, generally, summer, Generally, around the time of the road, the tire pressure can be increased because of the high temperature. And in the service area, you can take a portable tire pressure meter, which is high and deflated.

It is not that the tire pressure is high and it is easy to puncture, but that the tires of fast cars need to maintain high-speed operation for a long time, and the test of the tires is more stringent, and it is necessary to pay more attention to the tire pressure. Now there are some models that will be equipped with tire pressure monitoring, if there is no original configuration of tire pressure monitoring, you can also install it yourself, a treasure to buy about a few.

The tire pressure of a cold car in summer is not the same, the tire pressure is too high or too low, the tire pressure will be burst, the tire pressure will change within a range, and there will be values in the vehicle manual, one is empty, and the other is fully loaded.

Left and right can be tire pressure in, between are normal, the general recommendation is the tire pressure, in fact, each car has the tire specifications of the assembly, but also has requirements for how high the air pressure, how much tire pressure is not completely based on the tire model, the same tire installed on different cars will require different pressure of air pressure, so the so-called optimal tire pressure is not a fixed value, depending on their own model, the standard tire pressure value of a car can be found in your own user manual, Most models will be marked on the driver's side B-pillar, or attached to the inside of the fuel tank cap, but it should be noted that although the manufacturer has given a standard tire pressure, but it also depends on the temperature influence, the weather is hot in summer, the temperature is high and the gas is easy to expand, so the tire pressure will be reduced or, in winter it will be adjusted to the opposite.

Tire pressure changes often in summer at high speeds, but not so much in winter. Therefore, it is recommended that if you often run at high speed in summer, the tire pressure can be maintained, and if you often run at high speed in winter, you can basically maintain the tire pressure at it.

It is more appropriate to keep the tire pressure at high speed, and before driving the car at high speed, you must first check the operating condition of the car, especially the tires of the car.

Preferably around the right. Because the air pressure increases when the car is running at high speeds, the tire pressure is not necessarily set too high.

When the OEM leaves the factory, the standard tire pressure is set according to the vehicle condition and tire performance. On the highway, the tire pressure still maintains your usual tire pressure value, it is best to follow the car's reference number of sufficient air pressure, and most car owners ignore this detail. On the highway, remember the principle that tire pressure is slightly lower in the summer and slightly higher in the winter.

In general, summer is summer. One, a little higher in winter, one is fine. Standard tire pressures for tires can be found on cars, including fuel caps, drawers, doors, and driver's manuals.

The car is there all year round, neither high nor low. In summer, when the temperature is high at high speeds, the tire pressure will automatically rise, but this has no effect. They are all within the normal range and there is no alarm for tire pressure monitoring.

More refined drivers can adjust in the summer and in the winter, as long as there are no problems within the normal range, and if the tire grinds below the marking, try to replace it before driving at high speeds, because even if the tire pressure is within the normal range, there is a risk of a puncture. Regardless of whether it is high speed or not, first in the cold state, add the tire pressure according to the standard tire pressure of the main engine factory! When the tires travel more than 5 km, the temperature will rise normally at 70 to 80 tire pressure.

This is normal. Therefore, it is very important to increase the tire pressure correctly when cold tires! The standard tire pressure for each car is the most accurate to see the tire pressure marking.

Generally speaking, the door opens at the intersection of the door frame and the door frame B-pillar, and some are on the fuel tank cap. What are the specific values? But now tire shops, repair shops, and 4S shops will adjust the default tire pressure to, no matter what the model.

Although it is simple and crude, it is convenient and trouble-free, and there are generally no major problems. The normal tire pressure for most wheels is around this value. If the tire pressure is lower than there is a problem, it is basically a loss of air, and the tire will shrink.

Find a place to inflate. Also, correct one thing, don't add a little less in the summer and a little more gas in the winter. The correct way to do this is in both winter and summer, regardless of whether the weather is cold or hot, and the tire pressure is in line with the standard tire pressure marked by the OEM.

Because the tires travel more than 5 kilometers, the temperature will be 70 to 80 degrees much more than the change in temperature. The OEM has long considered it, and it only needs to follow the standard tire pressure. In addition, tires naturally lose tire pressure every month.

Many people believe that tires are sealed and the air pressure does not change. The reality is that the car cannot be moved or driven normally, and the tire pressure for a month will be lost. So it's important to check your tire pressure every month!

If the vehicle does not have tire pressure monitoring, it is recommended to install it. It's okay to have a higher tire pressure, but I'm afraid of running out of air. Normal tires are able to withstand however, the risk of tire bursts increases greatly if you drive below tire pressure on the highway.

In addition, remember to inflate the tires when they are fully loaded, it doesn't matter, otherwise the tire gas will shrink, the tire will be deformed too much during driving, increasing tire wear, and internal heat will easily lead to a puncture.

The tire pressure value is coming, but when running at high speed, the tire pressure is higher than usual, so we must pay attention to the speed problem when driving and don't drive too fast.

The tire pressure in winter and summer is completely different, it should be grasped between 220 and 260, if the tire pressure is relatively low, there will be a lack of power, and there is a possibility of a puncture.

Generally, 220-260kpa is more suitable, and this running speed can also be more suitable for highways, and it will not cause tire punctures.

It is recommended to drive at high speed over long distancesTire pressureIt can be appropriately raised. While proper tire pressure may reduce comfort, it can reduce the heat generated by rolling, which can be very beneficial for long drives. The appropriate range can be considered no more than the car plant.

Recommended full tire pressure recommendation or standard value. Tires may face a name "standing wave" when driving at high speeds.

Effect" This question is related to tire pressure. "Standing wave effect" Generally speaking, the rebound of the tire after the concave surface** does not return to normal roundness.

Concave again, repeatedly forming a superposition effect, the rubber molecules generate a lot of heat and damage.

Normal tire pressures are generally in between, with city SUVs being slightly lower and sedans being slightly higher. If you are running at high speeds, you can check the tire pressure in advance and set the tire pressure in between. This range of tire pressure allows for good fuel economy and also ensures tire grip.

If the tire pressure is too high, the taekapphire crown will bulge in the middle, the tire will be overworn, and the grip will be reduced. The tire pressure when driving on the highway should not be too high or too low, normal standard. Usually, the tire pressure of the front wheel is the tire pressure of the rear wheel2...

5。Tire pressure that is too low will cause the tire temperature to rise, making it easy to get a puncture. If the tire pressure is too high, it is also easy to burst the tire, and the tire pressure can generally be kept slightly higher when the car is driving at high speed for a long time, which is better and safer!

Normal tire pressures are generally between, with urban SUVs and cars likely to be slightly lower. If you are driving at high speeds, you can check the tire pressure in advance and set the tire pressure between them. This range of tire pressure allows for good fuel economy and also ensures the grip of the tires.

If the tire pressure is too high, the taekapphire crown will bulge in the middle, the tire will be overworn, and the grip will be reduced. When driving on the highway, the air pressure generally refers to the requirements of the car manufacturer, and the general requirement is a spare tire.

The air pressure is about 3 If it is too high, the contact area between the tire and the ground will become less frictional force.

It will reduce the handling of the vehicle will be reduced The wear in the middle of the tire tread will be relatively large At the same time, if the tire pressure is too high, it is equivalent to overloading the tire It will shorten the service life of the tire If it is too high, the tolerance of the tire will also be reduced, which will cause driving safety hazards.

Even protect the tires.

If it is too low, the contact area between the tread of the tire and the road surface will become larger. The wear on both sides of the tire will be more severe. The tire pressure is too low.

Standing waves will be formed when the tires roll, that is, the tire deformation recovery speed cannot keep up with the tire agitation speed The formation of standing wave tires will produce a lot of heat There is a potential danger of puncture The normal range of car tire pressure is that the car can be charged on the highway. It is important to note that the pressure of high-speed tires on a car should not be too low. If the tire pressure is too low (lower), each time the tire rolls, the greater the tire deformation, the greater the deformation of the wire in the tire, which is equivalent to driving back and forth in the tire every time the tire rolls, and the wire in the tire is fatigued and broken, and the tire may **.

Therefore, before hitting the highway, it is essential to check the tire pressure of the car to ensure the correct value.
