Midsummer is coming, 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 work, coupled with the high temperature outside, it will intensify the aging of many rubber parts on the car, among which the tires in particular need special attention. Many people are used to taking advantage of loopholes, crossing the road instead of walking on zebra crossings instead of crossing railings, and jumping in line instead of waiting in line to buy groceries. When it comes to tire maintenance, car owners must not take advantage of loopholes, because high-speed tire blowouts are no joke.

Summer tire use must be scientific

1. The rubber surface of tires is more likely to age under high temperatures, and in severe cases, tire blowouts may occur. Therefore, pay special attention 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 at high speed for a period of time, you should stop the car immediately to cool down. But be sure not to splash it with cold water, let alone deflate it, otherwise it will cause a puncture and early damage to the tire.

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

3. Always clean foreign matter in tire tread grooves. If you find that a nail has penetrated a tire, do not rush to pull it out. You should drive to a professional tire shop for help immediately.

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

5. If a tire blowout occurs while driving at high speed, don’t panic. The first step is to keep yourself as calm as possible and don’t swerve 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 wander. Do not compete with the inertia of the vehicle and try to keep the vehicle traveling in a straight line. When it is safe to do so, 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.

Be careful in summer tire maintenance

1. Tire rotation extends tire life. Because of the need to turn the steering wheel, the front wheels of a car wear faster than the rear wheels. Often, when the front wheel patterns are polished, the rear wheels are still in good condition. In order to extend the service life of the tires and balance the wear of the front and rear wheels, tire rotations must be performed regularly. Experts recommend that front-wheel drive vehicles should be diagonally adjusted front and rear every 8,000 kilometers to make the tires wear evenly.

2 Positioning and dynamic balancing are essential. When replacing or installing tires and wheel hubs, the positioning angle of the tires and the mass distribution of the wheel hubs will change. The most direct impact is uneven tire stress. Some tire treads are severely worn locally, which can easily lead to long-term or high-speed driving in summer. Flat tire. To change the irregular wear of tires, four-wheel alignment and dynamic balancing should be performed regularly.

3 Maintain normal tire pressure. The increase in tire pressure is mainly due to the expansion of air in the tire, so it is a good choice to fill the tires with dry nitrogen in summer. 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 long time and greatly reduce the chance of tire blowout. Practice has proven that nitrogen-filled tires can travel 50,000 kilometers without the need for air replenishment, and dry nitrogen does not contain moisture and will not cause oxidation of the inner wall of the tire rubber.

4 Don’t ignore the car spare tire. In the event of tire failure, the spare tire carried with the vehicle can come in handy. However, many car owners usually check the tires in place, but ignore the spare tire. In an emergency, they discover that the spare tire has insufficient air pressure, the valve core is damaged, or the shelf life has expired. Experts remind that daily tire inspections should also include spare tires.
