In the hot summer, the temperature is high, this is the season when cars are more prone to punctures. In summer, the road surface temperature is often above 70°C. A car that has been driving in hot weather for a long time will easily cause a puncture or rapid wear due to high tire pressure.
According to incomplete statistics, 46% of highway accidents are caused by tire failures, and a puncture alone accounts for 70% of the total number of accidents. What are the reasons for the frequent occurrence of tyre bursts on expressways? Now, please study with the after-sales engineers of Beijing Sunshine Aoda Automobile Sales Co., Ltd.:
1. The temperature is high. When a car is running under high temperature conditions, due to thermal expansion and contraction, the tires are prone to deformation and the tensile strength will decrease. In addition, the tires continue to heat up during the driving process, but the heat dissipation is relatively slow, so the air pressure changes The increase in the carcass will result in a puncture due to a thin carcass.
2. Abnormal tire pressure. Abnormal tire pressure can cause local tire wear, reduced handling and comfort, and increased fuel consumption. When the tire pressure is insufficient, the sidewall of the tire is likely to bend and break and burst. If the tire pressure is too high, the defect of the tire will burst during high-speed driving.
3. The tires are in poor condition. Excessive wear, aging, cracking and trauma of tires are also one of the reasons for tire blowouts.
4. The road conditions are not good. Road conditions also have a great impact on tires, such as uneven or gravel roads. When the vehicle is driving at high speed, the tires rub against sharp stones or other sharp objects on the road, causing air leakage and puncture.
5. Speeding. The speed limit of each tire is determined by strict calculations by the manufacturer. When speeding, the tire temperature will rise rapidly, which accelerates the aging of the rubber and is prone to delamination and bursting.
6. The vehicle is overloaded. It is self-evident that the overload of vehicles is harmful to the tires, especially when we often see some large trucks overloaded on the highway, at this time the tires are more prone to puncture accidents.
In order to ensure driving safety to a greater extent, learn how to reduce the hidden danger of tire blowouts in summer, and it is not negligible to conduct daily tire maintenance and inspection:
Keep the tire pressure at the standard air pressure. Unstandard tire pressure will cause excessive wear of the tires and cause tire bursts. It is essential to install a tire pressure monitoring system on the vehicle. If the air pressure is too high, the tires will overheat, so you should stop to cool down and reduce the pressure naturally. When the tire pressure is too low, inflate it in time, and check whether the tire has chronic air leakage, so as to replace the tire with good airtightness.
Regularly maintain the vehicle. The car mainly has a clear understanding of the tire wear indicator and the tire production date, and regularly maintains the vehicle. Check the condition of the tires before going on the highway. At the same time, do not use the spare tire for long-term driving.
Periodically rotate the tires. Owners regularly implement tire rotation, usually in the second level of maintenance, and correct the balance of the wheels. Cars that often drive on highways should adopt the circular shift method.
