How to prevent flat tires during summer tire maintenance

Midsummer is here and the temperature is rising day by day. This season is equally difficult for cars. Because the car itself needs to dissipate a lot of heat during operation, coupled with the high temperature outside, it will increase the aging of many rubber parts on the car, and the tires in particular need special attention. Many people are used to taking advantage of loopholes, crossing the road instead of using zebra crossings instead of crossing railings, skipping queues to buy groceries. When it comes to tire maintenance, car owners and friends must not take advantage of loopholes, because a quick tire blowout is no joke. .

Summer tire use must be scientific

1. The rubber surface of tires is more likely to age at high temperatures, and a puncture will occur in severe cases. Therefore, special attention should be paid to the air pressure of tires that have been used for a certain period of time. If you find that the tire wall is overheated and the air pressure is too high after driving quickly for a period of time, you should stop immediately to cool down. But be sure not to splash it with cold water, and there is no need to deflate it, otherwise it will cause a tire blowout and early damage to the tire.

2. Pay attention to cleanliness when inflating, and the inflated air must not contain moisture and oil to prevent the inner tube rubber from deteriorating and being damaged.

3. Always clean up foreign matter in tire tread grooves. If you find that a nail has penetrated between the tires, do not pull it out in a hurry. You should immediately go to an unprofessional tire shop for help.

4. Generally, the service life of tires specified by manufacturers is 80,000 to 100,000 kilometers (or about 5 years), and there will be certain safety hazards for tires that are facing retirement.

5. If a tire blowout occurs while driving quickly, don’t panic. The first step is to keep yourself as calm as possible. There is no need to change direction or brake suddenly. Hold the steering wheel tightly with both hands, do not put the car in neutral and slowly apply the brakes to reduce the speed of the car evenly. After a tire blowout, the vehicle body will deviate. There is no need to compete with the inertia of the vehicle. Try to keep the vehicle traveling in a straight line. After confirming safety, slowly reduce the speed of the vehicle, put up a hazard warning sign behind the vehicle after it has stopped, and replace the spare tire immediately.

Careful tire maintenance in summer

1. Tire rotation extends tire life. Due to the need to turn the steering wheel, the front wheels of the car wear out faster than the rear wheels through friction. Often when the front wheel patterns are polished, the rear wheels are fine and there is no problem. In order to extend the service life of the tires and balance the friction and wear of the front and rear wheels, tire rotation must be carried out regularly. Experts suggest that front-wheel drive vehicles should be rotated diagonally every 8,000 kilometers to make the friction wear of each tire even.

2. Positioning and dynamic balancing are essential. When replacing or installing tires and wheels, the positioning of the tires and the quality distribution of the wheels will fluctuate. The most obvious consequence is that the tires are unevenly stressed. Some tire treads have heavy local friction losses. When driving for a long time or driving quickly in summer, It can easily lead to a tire blowout. To change the irregular friction loss of tires, four-wheel alignment and dynamic balancing should be carried out regularly.

3. Maintain normal tire load. The most important reason for the increase in tire pressure is the expansion of air in the tire. Therefore, filling the tires with dry nitrogen in summer is a good choice. Nitrogen is an inert gas with a low expansion coefficient and does not easily rise as the ambient temperature rises. It can maintain normal tire pressure for a longer time and greatly reduce the probability of tire blowout. Practice shows that if you travel 50,000 kilometers with nitrogen-filled tires, you still don’t need to replenish the air, and dry nitrogen does not contain moisture and will not cause oxidation of the inner wall of the tire rubber.

4. Don’t neglect the spare tire of your car. In the event of tire failure, the spare tire carried with the vehicle can come in handy. However, many car owners usually check their tires properly, but neglect the spare tire. Only in an emergency do they discover that the spare tire has insufficient air pressure, the valve core is damaged, or the warranty period has expired. Experts remind that normal tire inspections should also include spare tires.

There are ways to use tires

When choosing and using tires, you should follow a scientific method, otherwise the service life of the tires will be greatly reduced due to multiple factors. Here are the precautions:

Parking:

1. Tires should be kept away from heat sources, power generation facilities and locations where ozone is generated.

2. Tires must not be too close to oil, flammable substances and chemical corrosives.

Air pressure:

1. Tires should be inflated according to the air pressure of the "air pressure load correspondence table" stipulated in national standards.

2. After inflating the tire, check whether there is air leakage in all parts. If air leakage is found, repair it in time.

3. The tire must ensure normal internal pressure during use. When running or working for a long time, the tire pressure should be checked regularly.

4. When parking for a long time, the front and rear axles must be set up.

5. If the air pressure is too high, the tire will easily wear out and explode; if the air pressure is too low, the tire will easily change shape and be crushed.

6. When twin tires are installed together, the two tires should be inflated at the same level, and one should not have a high pressure and the other should have a low pressure.
