What do I need to pay attention to when inflating tires? How to inflate tires

1. Pay attention to safety when inflating. Check the air pressure with a barometer at all times to avoid bursting the tire due to overinflation.

2. After stopping driving, you must wait for the tires to dissipate heat before inflating, because the tire temperature will rise when the vehicle is driving, which will affect the air pressure.

3. Check the valve.

4. Pay attention to cleaning when inflating. The filled air must not contain water and oil to prevent the rubber of the inner tube from deteriorating and damaging.

5. When inflating, it should not exceed the standard too much and then deflate, nor can it be inflated too much because it cannot be inflated for a long time, if it exceeds the standard too much, it will promote the cord to stretch excessively, causing its strength to be reduced, affecting the life of the tire.

6. Before inflating, the dust on the valve should be wiped off, do not loosen the valve core, and after the inflation is completed, soap foam water (or saliva) should be applied to the valve, check whether there is air leakage (if the air leaks, small bubbles will be generated), and the valve cap should be fully installed to prevent sediment from entering the valve.

7. When the radial tire is inflated, due to structural reasons, its sinking amount and grounding area are large, and it is often mistaken for insufficient inflation and excessive inflation; Or, on the contrary, because the amount of sinking and the ground area are already large, it is also mistaken for sufficient when the air pressure is insufficient. It is measured using a standard barometer. The air pressure used for radial tires should be higher than that of ordinary tires by centimeters.

8. The barometer of the vehicle or the barometer used in the tire workshop should be calibrated regularly to ensure the accuracy of the air pressure inspection.

When the car is inflated, you should pay attention to the tire medicine prescribed by the car. When it's time to cheer up, the sun on the four tires should be consistent. This refers to small cars if they are trucks. His tyres, the Suns, are also going to be consistent.

What do you need to pay attention to when inflating tires, don't inflate the tire pressure too much, and the national football team is prone to accidents.

Car tires can be inflated with an inflator pump.

1. To start the car with the key, you can turn on the cigarette lighter socket at the ACC position, then press the switch of the inflator to the "0" position, plug in the power plug, and the indicator light will light up. If the battery is low, it is best to start the engine to make sure the battery has enough charge.

2. Place the inflator flat on the ground and it will be displayed on the display". If the display is incorrect, press and hold the middle yellow key for more than 5 seconds to reset.

3. Unscrew the tire valve cover, place it in place, and then screw the inflator tube of the inflator to the tire valve through the connector. The valve must be tightened in place and cannot be operated.

4. At this time, the inflation pressure of the current tire is displayed on the screen of the inflator. Note the units displayed, including bar, pounds, square inches, and kilopascals. You can press the yellow button to toggle.

5. Press the key to the right of the yellow key, set the value displayed on the screen to 30 pounds square inch, and then press the inflator switch to the "1" position, and the inflator starts working. The value on the screen will gradually rise to 30, and pause for a few seconds before continuing to inflate until the tire pressure has stabilized at 30 pounds square inches.

6. Press the inflator switch to the "0" position and unscrew the joint of the inflator pipe from the tire valve. Move quickly to prevent the full air from running out. Then unplug the power plug and turn back the valve cover of the tire.

Note: The tire pressure of the general family car is, which is converted to 2, which is 2 kg to kg that the car repairer usually says. 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.

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.

Determine how many atmospheres you want to put your car tires on. Mine is that you can see a sign at the driver's door, so let's look for it yourself. Here is a reference, for common cars, the original tire pressure standard for passenger cars is 230kpa 250kpa, which is within the normal range, the highest should not exceed 300kpa, the lowest should not be lower than 210kpa, it doesn't matter if it is a little higher, but low pressure is very dangerous.

Unscrew the cap on the tire inflatable head. Pay attention to put it away, and cover it last.

Choose the right valve. The cars on them are basically American-style valves, which are easy to distinguish.

Plug in the air valve. Open the air clamp first, insert the inflation head, and then close the air clamp. You can open and close the air clamp by yourself and try it before operating.

Pep talk. In fact, it doesn't take a lot of effort, and it's lighter than hitting a bicycle tire, because the air pressure of a car is smaller than that of a bicycle. And I also chose the most common pump.

About 15 hits, an increase of 10kpa. Everyone should also pay attention to themselves, and when the second tire is hit, calculate how many times it will be hit according to experience.

The final tire pressure is determined by a tire pressure test. If it's too high or too low, just inflate and deflate it yourself.

Close the cap on the inflatable head. Protect the inflatable head so that it doesn't get dirty later.

Hope, thank you!

Connect the air duct of the air pump to make sure that each section of the air duct is tightly connected. Connect the power cord of the air pump and connect to the cigarette lighter in the car to ensure that the engine is running. Turn on the air pump switch, connect the air duct to the tire valve, and tighten the interface nut.

When the tire pressure value displayed by the air pump is close to the standard value, turn off the air pump and close the valve cap.

When inflating, it is necessary to observe the scale of the air pump pressure gauge at all times. Water can be applied to the mouth of the valve to simply test whether the valve is leaking. Pumping should be carried out under cold tires, just after driving the tires, the internal air becomes hot, at this time the measurement and pumping value will be inaccurate, so you need to wait for the vehicle to cool down before pumping.

To buy a tire pressure gauge, the measurement value must be accurate, and it is best to have a measurement certificate. The inaccurate value of the tire pressure gauge directly leads to the wrong tire pressure, which is a potential danger to the tires and safety of the car. Car owners can use their own tire pressure gauge to measure again and compare the results after pumping up at the 4S shop.

Pay attention to these points when inflating tires, and the old driver will teach you how to inflate them properly.

1.Find out the tire pressure range of the car itself:

There are many types of tires, and the tire pressure value of each type of car tire is different. Before inflating, be sure to figure out the range of tire pressure values of the car itself; The tire pressure range can be seen in the car manual or on the right door frame on the right side of the car. Of course, if the door has been painted, this sign is gone.

Automobile tire pressure is divided into no-load tire pressure and full-load tire pressure, which is generally measured in psi.

2.Measure the tire pressure first when inflating:

It is very difficult for car tires to blew unless the tire is punctured by nails and then bleed; If it is tied, there is a potential safety hazard, so check the tire pressure before inflation and feel the tire for nails. If the tire pressure is between the empty and full tire pressure, there is no need to inflate; If it is lower than the no-load tire pressure, you have to pump up; If it is higher than the full pressure of the tire, let out a little air.

3.Pumping Tools:

There are two kinds of car inflatable tools: manual and electric, and some electric air pressure pumps have tire pressure gauges, but they need to be plugged in; You can also pump up with a bicycle pump. Of course tired. The pump increases around every 15 times.

You can explore this on your own. Manual pumping is more tiring, suitable for a small amount of qi, but can be used as a means of fitness.

4.Test the tire pressure again after manual inflation:

If the pump does not have a tire pressure gauge, it needs to be measured with a tire pressure gauge separately; If you're using a pneumatic pump, don't! If the air pressure is exceeded, you can use the deflation function of the tire pressure gauge to press and deflate until a reasonable value is reached.

5.The tire pressure gauge should be accurate:

Buy *** tire pressure gauge, the measurement value must be accurate. It is advisable to have a certificate of measurement; Inaccurate tire pressure gauge directly leads to inaccurate tire pressure, which is a potential danger to car tires and safety. You can refuel at the 4S shop and measure again with your own tire pressure gauge to compare the results.

6.The tire pressure should be the same for all four tires:

A car has four tires. The inconsistency of the left and right tire pressures will cause deviation, body trembling, and wear and tear, so it is best to have the same tire pressure among the four tires; At least make sure that the tire pressure of the first two tires is the same, and the tire pressure of the rear two tires is the same.

Car tire inflation, pay attention to the size of the standard inflation pressure, really help you look forward to it,

1.Pay attention to safety when inflating. Check the air pressure with a barometer at any time to avoid over-inflation and puncture.

2.Heat is dissipated first, then inflated. After the vehicle stops driving, you need to wait for the tires to dissipate heat before inflating, because when the vehicle is moving, the temperature of the tires rises, which affects the air pressure.

3.Check the valve. If the fit between the valve and the valve core is uneven, there are convex and concave phenomena and other bending defects, it is not wide to facilitate inflation and measurement of air pressure.

4.Pay attention to cleanliness when inflating. The filled air body should not contain water and oil to prevent deterioration and damage to the rubber in the tire.

5.Never go over too much. When inflating, it is not advisable to deflate if it exceeds the standard too much, and it is not advisable to inflate too much after going out for a long time. If the standard is exceeded too much, the cord will be stretched too much, affecting the service life of the tire.

6.Check for air leaks. Before inflation, the dust on the valve should be wiped clean, and the valve core should not be loose. After inflation, soapy water should be applied to the valve to check for air leaks.

Millions of car purchase subsidies.

1.Pay attention to safety when inflating. Always check the air pressure with a barometer to avoid tire blowouts due to overinflation.

2.After stopping driving, wait for the tires to dissipate heat before inflating, as the temperature of the tires will rise when the vehicle is moving, affecting the air pressure.

3.Check the valve. If the fit between the valve and the valve core is uneven, there are defects such as convex and concave phenomena, and it is inconvenient to inflate and measure air pressure.

4.Pay attention to cleanliness when inflating. The filled air body should not contain water and oil to prevent deterioration and damage to the inner tube rubber.

5.When inflating, do not deflate after exceeding the standard air pressure too much, and do not inflate too much, because you cannot inflate after going out for a long time. If the standard is exceeded too much, it will cause the cord to stretch too much, reduce its strength, and affect the life of the tire.

6.Wipe off the dust off the valve before inflating and do not loosen the spool. After inflation, apply soapy water (or saliva) to the valve, check for air leaks (if there is an air leak, small bubbles will be produced), and tighten the valve cover to prevent sediment from entering the valve.

7.When radial tires are inflated, due to structural reasons, their sinking and grounding areas are large, which are often mistaken for underinflation and overinflation; Or, on the contrary, due to its large amount of sinking and large ground contact area, it is mistaken for a sliding balance when the air pressure is insufficient. Measured with a standard barometer.

The air pressure of a radial tire should be kilogram square centimeter higher than that of a normal tire.

8.The truck barometer or the barometer used in the tire shop should be checked regularly to ensure the accuracy of the barometric pressure check.
