How do you determine the tire pressure? How to maintain your tires?

It can be inspected and maintained from the following aspects:

1: Check the tire pressure regularly.

Tire pressure is an important factor affecting the life of tires, do not be too high or too low, and inflate according to the tire pressure indicated by the vehicle. Try to keep the tire pressure low in the summer; In the cold winter, try to ensure that the tires of the car are more inflated than in summer, because the tires are easy to expand and contract. This is a comfortable and safe way to drive.

2: Check the wear and tear of your tires frequently.

Sometimes individual vehicles will "eat tires", which is necessary to check the tires frequently, especially the inside, to see if there is abnormal wear, mainly to observe whether the depth of the tread on both sides of the tire is consistent.

3: Remove small stones and other foreign objects in the tires in time.

Foreign objects in the tire pattern are potentially dangerous and can easily splash out when the car is moving. Therefore, if you find small stones, you should use a key to pick them out and try to ensure that the tires are clean.

4: Rotate tires on time.

The front wheel of the car is a steering wheel, the wear is relatively large, generally in order to reduce the wear of the front wheel, after the first warranty of the vehicle, every 5000 kilometers or so for a four-wheel replacement, preferably diagonal replacement.

5: Four-wheel alignment at regular intervals.

When the vehicle deviates or other abnormal steering, it is necessary to position the tires in time to avoid other abnormalities in the tires. Four-wheel alignment ensures that the four tires of the vehicle are evenly stressed and avoids excessive wear.

6: Repair the tire in time.

If the vehicle has nails, even if there is no air leak, replace the spare tire as soon as possible, and then replace the nail tire. I have experience, in fact, sometimes I don't need to change the spare tire when I tie the nails, let the tire repair master look at the nails first, if the nails are not big and not deep, the tires may not be blown up, so there is no need to change the spare tire.

The most direct way is to install a tire pressure monitoring system, tires generally do not need maintenance, usually we wash the car is to put some tire wax.

Yes, with a tire pressure gauge, first of all, the tire pressure is in the standard range, and the pressure value is too large or too small, which will have an impact on the tire. It is recommended to do four-wheel alignment before 20,000 to 30,000 to reduce the impact of vehicle parameters on tires.

To determine whether the tire pressure is normal, we can judge whether the vehicle is out of air by looking at the amount of contact between the tire sidewall pattern and the ground。For family car tires, if there are four to five tread blocks touching the ground, then the tire pressure is normal. If there are more than five, the tire pressure may be insufficient at this time, and the tire pressure needs to be supplemented; If there are less than four contact surfaces, the tire pressure is too high and you need to deflate.

Using instrument inspection, the more common tire pressure gauges are divided into: pointer tire pressure gauge and electronic tire pressure gauge. For the pointer type, press the bleed valve, reset the pointer to zero, align one end of the interface with the tire valve, and then tighten.

In this case, the value that the pointer points to is the tire pressure value.

Maintaining your tires starts with controlling your driving speed. In the cold winter, if you stop and restart, you need to start driving at a lower speed for a while after starting to drive at normal speed because the tires are stiff. Of course, the most important thing for safe driving in winter is to control the driving speed.

Especially when driving on the highway, it is necessary to pay attention to controlling the speed of the vehicle and not to accelerate or brake suddenly, so as to ensure safety, effectively protect the car and tires in the cold season, and avoid traffic accidents.

Second, check your tires regularly. You can check it regularly every week, or every time you wash the car, to see if there are bulges, cuts, nails, valve glue aging, abnormal wear, etc., if there is damage, the tire should be replaced in time. Of course, in addition to the appearance of the tire, remember to check the tire pressure together to ensure that the tire pressure is within the normal range.

Also, it is important to know that tire pressure is very important for cars. If the air pressure is too low, the deformation of the carcass increases, the sidewall is prone to cracks, and at the same time, buckling movements are generated, resulting in overheating, causing rubber aging, cord fatigue, and cord damage. It also increases the ground contact area of the tires and makes the tires accelerate.

Shoulder straps. Excessive air pressure will cause the tire cord to be overstretched and deformed, and the elasticity of the carcass will decrease, increasing the load when the car is driving. If there is an impact, internal cracks and ** will occur.

and reduce rolling resistance.

You can use a tire pressure gauge to take the following measurements; When the mountain is round, you should clean the small stone only of the car tire Rika, try not to drive out in the rainstorm, you can go to a professional 4S shop for maintenance.

It can be checked by the instrument, and the maintenance of the tire needs to determine whether there is cracking, whether there is air leakage, and better adjust the tire pressure.

If the tire pressure indicator light on the car is on, it means that the pressure may be insufficient; Drive slowly when crossing speed bumps, and avoid running uneven areas.

There are many factors that determine fuel consumption, and tire pressure is also one of them, which has little effect. The tire pressure of a car's tires has an impact on fuel consumption. If the tire pressure is too low, the driving resistance of the car will increase, resulting in increased fuel consumption.

Tire pressure that is too low can also cause tire wavy, heating and puncture, which is also very dangerous. Similarly, high tire pressure will reduce the contact area between the tire and the ground, affect the braking distance, and are prone to punctures. Just follow the instructions to flush the tire pressure.

To put it in layman's terms, the lack of tire pressure in the car, the contact surface between the tire and the ground further increases, resulting in an increase in friction, and the required kinetic energy will rise, resulting in an increase in fuel consumption. Tire mega bump pressure has a great impact on fuel consumption, so it is necessary to check and check the tire pressure regularly. Tire pressure not only affects fuel consumption, but also has an important impact on ride comfort and driving safety.

Tire pressure that is too low will increase tire crease rolling, leading to tire damage. When the pressure is too high, the tire temperature will rise at high speed, and the tire temperature will further increase the tire pressure, which is also very dangerous. Flat tires at high speeds in summer are caused by high tire pressure.

The tire pressure shall be tested according to the specified value in the vehicle manual, and shall not be increased or decreased at will. Although the safe range of tire pressure is large, the range of tire pressure changes cannot be ignored as the ambient temperature and tire temperature change. On the other hand, just like in winter now, it is sometimes necessary to turn on the heating, which will still lead to a further increase in fuel consumption in the event of slow driving in the city, congestion, etc., which will be relevant.

If you are not at ease, you always feel that the fuel consumption is high, you can go to the repair shop to check whether the parts are normal.

On the one hand, it is also related to your driving habits. For example, if you start too strongly, you must have good driving habits to make our car fuel-efficient and fuel-saving to "prolong life". When driving, you must develop good driving habits, try to drive in a gentle and peaceful way, don't slam the accelerator, step on the brakes, and do more.

Take good care of your car on time so that it is in good working order. Plan when traveling and avoid congested construction roads. Try not to drive with a full load, and remove unusable items from the car in time.

The tire pressure of a car's tires has an impact on fuel consumption. If the air pressure of the tires is too low, the direction will be particularly heavy, the contact surface between the tires and the ground will become larger, and the car will run more meaty. If the air pressure of the tires is normal, the car will run very lightly, the steering will be nimble, and the fuel consumption will naturally decrease.

1. Usual maintenance. The main thing is to remove stones from the gaps in the tires. The reason why tires have patterns.

It is for driving on rainy roads. Drained. Slick tires have the best grip.

However, if there is rain, it will slip, so don't let foreign objects fill the tire gaps. Medium infiltration.

2. In general. Family cars do not need to be ventilated frequently. A tire pressure check once a quarter is fine.

3. The air pressure value of the tire pressure of the automobile tire in winter and summer is negotiable according to the car. It's best to look at your vehicle's factory maintenance manual. The reason why the tread will be whitish when running at high speeds, which is more practical and sells the spine of his own model 4.

The tires are all rubber products. It is generally black and does not turn white on its own. Presumably the main reason is the road surface.

Cement pavement or the adhesion of dirt may change the color of the tread.

Tyre pressure checks must be done monthly: Tyre underpressure and overpressure will lead to abnormal wear and tear of tyres, shorten the life of hand-penetrated tires, increase fuel consumption and even increase the chance of punctures.

If you want to maintain car tires, in the daily maintenance, you must pay attention to the stones in the tires in time, and pay attention to the cracks in the tires.

According to the survey, the largest cost of vehicle equipment consumption is car tires. As we all know, tires are one of the main components of a car, and it accounts for about 20 percent of the cost of a car25％。

The service life and mileage of tires are directly related to transportation costs and economic benefits. Therefore, it is necessary for drivers to understand how to reduce the wear and tear of tires, improve their service life and mileage, and reduce equipment consumption costs while the vehicle is driving. Here are some lessons learned from reducing tire wear.

Under standard operating conditions, the critical speed of the truck tire is 200 km h, and the passenger tire is 120 km150km h. Due to the slower development of truck speed, the critical speed has little effect on the truck tyre, but it has a considerable impact on the passenger tyre, which is constantly increasing the speed (up to 300 km h).

The speed at which a vehicle can be driven is usually determined by the technical performance of the vehicle itself, road conditions, outdoor air temperature, transport distance and tire quality. If the vehicle performance and road conditions are good, the temperature is not high, the transportation distance is short and the tires are high, the speed of the vehicle can be appropriately increased, and the speed of the vehicle can be controlled accordingly. According to statistics, accidents directly caused by tire problems on highways account for 8% of total accidents

10 (excluding tire bursts that did not cause an accident), which also illustrates the impact of high vehicle speed on tire life.

2) To grasp the temperature change of the tire in the summer driving, due to the high outside temperature, the tire heat accumulation is fast, heat dissipation is difficult, with the influence of factors such as driving speed, transportation distance and road conditions, the tire temperature will rise sharply, and the air pressure in the tire will also increase (because when the volume is fixed, the pressure is proportional to the absolute temperature), thereby accelerating the aging of rubber and reducing the adhesion between the cord and the rubber, resulting in the hollowing or blasting damage of the cord layer. Therefore, attention should be paid to controlling the temperature of tires when driving in summer.

3) Master the correct driving method.

The car should not start too violently, and both empty and heavy vehicles should start at low speed and steadily. Loosen the clutch and accelerate should be properly coordinated to make the vehicle start slowly, avoid the tire and the ground dragging, and accelerate the tread wear.

Driving on good roads, you should keep moving in a straight line, except for meeting cars and avoiding obstacles, it is forbidden to swing left and right and turn sharply to prevent the tires from being damaged by lateral cutting between the tires and the rims, and also to ensure driving safety.

In the summer, because the weather is hot, we can adjust the tire pressure of the car appropriately, and the tire pressure is best not to exceed in the summer. In winter, it can be turned up higher than normal.

Tire pressure should be between, this tire pressure is the safest and most secure, usually should develop a good habit of using the car, do not brake urgently, be sure to buy from regular channels, and the habit of using the car should also be changed, after a period of time try to check and maintain it.

Of course, for tires, his tire pressure is very large, then, how much is the safest tire pressure of car tires, I personally feel that between, this tire pressure is the safest and most secure

It is the safest to choose to replace the tires at ordinary times, and often test the use of tires to avoid some bumpy roads.

The tire pressure of the car is about, and the tire pressure required by different cars is also different, you can look at the sign on the tire, and it is more reasonable to operate according to the requirements of this car.

Abnormal tire pressure will lead to uneven wear of tires, reduce the comfort of driving, and be more related to the safety of driving, and may lead to punctures in serious cases.

Generally speaking, the tire pressure of the car is between 230-250kpa for the normal range, however, the specific normal tire pressure of the car should also be subject to the manufacturer's recommended value, which can generally be found in the car owner's manual, the label next to the cab door (near the B-pillar), the drawer next to the driver's seat of the vehicle, and the small door of the fuel tank cover. It will be marked in great detail with the specific tire pressure used.

In addition, the tire pressure standard is also related to the type of tire and the type of tyre, which varies from model to vehicle with different weights, heights and tire sizes, and the required tire pressure is also different. The tire pressure is 240kPa-250kPa for standard tires and 280kPa-290kpa for enhanced tires.

In addition, the tire pressure of cool tires is also different from that of hot tires, and the pressure of hot tires is about 20kpa higher than that of cold tires. The manufacturer's recommended value is the tire pressure value of cold tires, and the tire pressure in the cold car state is about 230kpa-250kpa, but the specific tire pressure marked on each car shall prevail.

In addition, the tire pressure is also greatly affected by seasonal factors, the temperature is high in summer, the tire is easy to heat up during driving, and the tire pressure is easy to cause a puncture if the tire pressure is high, and the tire pressure is slightly lower; The tire pressure in winter is a little higher than that in summer, because the cold shrinkage and heat rise, so the tire pressure of the car in winter is generally between 250kpa-280kpa.

The appropriate tire pressure value is very important for driving safety, and the tire pressure is not suitable, which will affect the normal driving of the car. Because the tire pressure is too high, the contact area between the tire and the ground will become smaller, and the pressure and wear per unit area will increase sharply, which is easy to cause brake loss of control or puncture, and the driving is easy to shake and the ride is uncomfortable.

If the tire pressure is too low, the contact area between the tire and the ground becomes larger, the direction is heavier, the fuel consumption of the car increases, and there will be a feeling of insufficient power. Due to insufficient tire pressure, it will cause deformation of the sidewall, and the aging of the internal steel wire and cord layer will be intensified, and the tire life will be shortened.
