Is it easy to have a flat tire in hot weather

Introduction: Car puncture is very common in our life for many reasons. Is it easy to have a flat tire in such hot weather? How to pre-tie tires in hot weather? Let's take a look!

Is it easy to have a flat tire in hot weather

When the weather is hot, the risk of being punctured will increase. There are many reasons for tire puncture, which can be summarized as follows: excessive wear, tire aging, overspeed and overload, too high or too low air pressure, impact or abrasion, tire bulging, tire puncture defects and so on. Among them, the tire pressure will change with the change of temperature. When the high temperature strikes in summer, the road surface temperature rises, and the tire pressure is easy to rise. Once the tire pressure is too high, it is easy to accelerate tire wear, resulting in a puncture.

How to prevent puncture in hot weather

In summer, the tire pressure is controlled at around 10%.

When the high temperature strikes in summer, the road surface temperature rises, and the tire pressure is easy to rise. Once the tire pressure is too high, it is easy to accelerate tire wear, thus causing tire puncture, so the tire pressure should be controlled at around 10% in summer.

Never drive continuously for a long time.

When the weather is hot, you should stop after driving on the highway for two hours to cool and depressurize the tires, but you can't sprinkle water on the tires to avoid tire deformation, shorten service life and let them cool naturally.

Try to avoid sudden acceleration and sudden braking.

When the temperature reaches 35℃ to 37℃ and the vehicle speed reaches 100 km, you should try to avoid sudden acceleration and sudden braking, because in this case, tire wear and instantaneous pressure increase are prone to tire puncture accidents.

Tire periodic transposition

Changing tires regularly can correct the wheel balance and make the tires on the same car wear evenly. If the wheel unbalance exceeds the standard, high-frequency oscillation will occur when driving at high speed, resulting in eccentric wear of tires, which is not conducive to driving safety.

Replace the tires in time.

High temperature in summer will accelerate the wear and aging of tire rubber and decrease the strength of steel wire layer. Generally, there are raised marks in the tire ditch to remind the owner to replace the tire in time. 6. Removing foreign bodies in tires is often to remove stones or objects in tread grooves to avoid tire crown deformation. Check the tire sidewall for cuts, stab wounds and exposed cords. If there is, it should be replaced in time.

Precautions for driving in hot weather

Prevent the body from overheating.

In summer, when the ambient temperature is high, the engine tends to overheat. Therefore, the inspection and maintenance of the engine cooling system should be strengthened in summer, and the scale in the water tank and water jacket and the sundries embedded between radiator fins should be removed in time.

Resistance to fuel gas

The higher the temperature, the faster the fuel (especially gasoline) evaporates, and the easier it is to form gas resistance in the oil circuit. Therefore, the fuel filter should be cleaned in time in summer to ensure the smooth oil circuit; When driving, cover the fuel pump with a damp cloth, spray water regularly to keep it moist and reduce the generation of air resistance. Once there is air resistance in the fuel system, immediately stop cooling, pull the manual oil pump and inject fuel into the oil circuit.

Anti-tire burst

In summer, the air pressure in locomotive tires will increase with the increase of temperature, which is easy to cause tire puncture accidents. Therefore, it is necessary to appropriately reduce the tire pressure before driving. If the tire temperature is too high while driving, stop the car in the shade to cool down, and don't use cold water to cool down.

Anti-fatigue and sleepy

In summer, the temperature is high, drivers lack sleep, and it is easy to get tired and doze off when driving. Therefore, before driving, you should pay attention to rest, ensure adequate sleep, make the best use of driving in the morning and evening, and avoid forming the habit of sleeping and driving.

Prevent high fever and heatstroke.

In summer, the sun is strong, the temperature is high, the driver sweats a lot, the energy consumption is large, and it is easy to get heatstroke. In order to prevent heatstroke, drivers should avoid eating spicy and greasy food, eat more fresh vegetables, drink more cold drinks, and pay attention to supplementing salt before and during driving.

Countermeasures of automobile tire puncture

1. The best way to deal with a flat tire is to hold the steering wheel tightly and do nothing else, and then slowly brake off the main road after the vehicle is stable. Remember not to brake suddenly, so as not to cause the vehicle to roll over or roll over due to uneven braking force.

2. Front tire puncture: Because the front wheel is related to the steering of the car, the puncture will have a great impact on the driving route of the car. Therefore, when the front wheel has a flat tire, the first action is to hold the steering wheel urgently, and then brake slowly and drive away from the main road after it is stable. In this process, you must not slam the steering wheel repeatedly, and at the same time, you must not suddenly brake. After parking, set up a triangle warning sign behind the vehicle to prevent secondary accidents.

3, rear tire puncture: Compared with the front tire, the rear tire is not so dangerous. The owner only needs to hold the steering wheel well, and then step on the brake pedal repeatedly, so that the center of gravity of the car can be moved forward, the intact front tire can be stressed, and the pressure of the tire after puncture can be reduced. Remember, don't press the brake pedal too hard.

4. If there is no spare tire emergency call. If you have a spare tire, you must find a flat and hard ground to replace it, and try to avoid changing the tire on the slope to avoid accidents when the jack slides down.

Last but not least, if you have a flat tire on the highway, you can't drive. It is necessary to arrange warning signs before and after in time, retreat to a safe place and wait for rescue to avoid secondary accidents.

Methods of preventing automobile tire from puncture

Driving on the road, car owners are most afraid of flat tires, especially in hot summer, so pay special attention when driving.

First of all, confirm whether it is a front tire puncture or a rear tire puncture?

If the front wheel has a flat tire, don't touch it with your hands. Be sure to hold the steering wheel tightly and adjust the direction of the front. Don't move too much, and don't move too hard. In addition, sudden braking is even more difficult. When the vehicle speed gradually decreases, drive the vehicle into the emergency lane, and then place a triangle warning sign at a certain distance (100-200m) behind the vehicle.

If the rear wheel has a flat tire, the car will drive through one of them. At this time, it is necessary to use the throttle to slow down the speed. It is worth mentioning that, unlike the front wheel puncture, the rear wheel does not have the guiding function, and the load-bearing capacity of the general car is relatively low in the later stage, so the rear wheel puncture is not very dangerous, just hold the steering wheel firmly.

How to pre-tie a tire?

1. It is most appropriate to control the tire pressure reduction at around 10% in summer.

When high temperature strikes in summer, the road surface temperature rises, and the tire pressure is easy to rise. Once the tire pressure is too high, it is easy to accelerate tire wear, resulting in a puncture. If the owner has sufficient funds, he can also fill the tires and spare tires with nitrogen. Nitrogen is an inert diatomic gas with extremely inactive chemical properties, low thermal expansion coefficient and low thermal conductivity. When the temperature changes, the degree of volume expansion is much lower than that of air, which reduces the probability of puncture. The tire filled with nitrogen has small deformation, improved grip, reduced rolling resistance and reduced fuel consumption.

2. In hot weather, you should stop after driving on the expressway for two hours, but don't sprinkle water on the tires to avoid tire deformation. At the same time, we should pay attention to stopping halfway to let the tires rest and cool down. When the tire is cooled and depressurized, it should be cooled naturally, and cold water should not be poured on the tire, which will cause cracks in the tire and shorten its service life.

3. Try to avoid sudden acceleration and sudden braking.

When the temperature reaches 35℃ to 37℃ and the speed reaches 100 km, it is easy to have a puncture accident. During long-distance and high-speed driving, sudden acceleration and sudden braking should be avoided as far as possible, because such a move will reduce the "capacity" in the tire, aggravate the wear of the tire, increase the instantaneous pressure, and thus lead to a puncture. Therefore, car owners should develop the habit of driving at medium speed when driving at long distance and high speed.

4. When parking, all four wheels should be parked on the same level ground. Never park your car on a rough road. Otherwise, the tire at the lowest position will be subjected to excessive pressure, which will lead to the deformation of the steel wire inside the tire and the tire damage.
