Statistics show that in the traffic accident on the highway, the accident occupancy rate caused by a puncture is more than 70%. From this we can see the importance of the tyre to the vehicle. Today, Xiao Bian talked to you about the seven taboos on the use of tires. I hope that the owners of the owners will pay more attention to them.
1, avoid tire overload work
The structure, strength, and use of air pressure and speed are determined by the manufacturer strictly. Tires that do not comply with the standards and are overloaded will affect their service life. According to experiments conducted by relevant departments, tire life is reduced by 20% at 10% overload, and rolling resistance increases by 45%-60% at 30% overload, and fuel consumption will also increase. At the same time overloading itself is strictly prohibited by the law.
2, avoid excessive tire pressure
Each automobile manufacturer has special regulations on tire pressure. Please follow the instructions. Do not exceed the maximum value. If the air pressure is too high, the weight of the vehicle body is concentrated on the center of the tread, resulting in rapid wear of the center of the tread. When impacted by external force, it is prone to traumatic and even explosive tire tread tension, resulting in tread delamination and cracking of the tread bottom cracking tires. The braking performance reduces the vehicle's beating, the comfort is reduced, and the vehicle suspension system is easily damaged.
3, avoid using the spare tire as a normal tire
In the course of using the vehicle, if it runs 100,000 to 80,000 kilometers, the user will use the spare tire as a good tire and use the original tire as a spare tire. This is absolutely not desirable. Because the use of time is not the same, the aging of the tire is not the same, so it is very unsafe. The tires are on the road, and the owners usually put on spare tires. Some owners do not remember to change the spare tires, and forget that the spare tire is just a tire that is ready for use.
4, avoid tire pressure
Insufficient tire pressure can cause the tire to overheat. Low pressure makes the tire's ground contact area uneven, tread or ply delamination, tread grooves and shoulder cracks, cord breakage, rapid wear of the shoulder area, shortening the service life of the tire, increasing the height between the bead and the rim The abnormal friction causes damage to the bead, or the detachment of the tire and the rim, and even the puncture increases the rolling resistance, increases the fuel consumption, and affects the control of the vehicle, even causing serious accidents.
5, avoid judgment by naked eye tire pressure
Tyres lose an average of 0.7 kg/cm2 of air pressure per month, and tire pressure changes with temperature. Temperature rises/falls by 10°C, and air pressure also increases/decreases by 0.07 to 0.14 kg/cm2. Measure the tire when it cools, and make sure to cover the valve cap well after measurement. Be sure to use the barometer to measure the air pressure. Don't judge it with naked eyes.
6. Avoid inconsistent left and right tire pressure
When the tire pressure on one side is too low, the vehicle will go to this side during driving and braking. At the same time, it should also be noted that the two tires on the same axle should have exactly the same pattern specifications. Different manufacturers and different patterns of tires can not be used at the same time for both front wheels. Otherwise, deviations will occur.
7, bogey is not timely remove tire foreign body
In the process of driving a car, the road surface varies greatly, and foreign materials such as gravel, nails, iron filings, and glass fragments are inevitably mixed in the tread pattern. If they are not cleared in time, some of them will fall off on their own, but there are A considerable part of them will become more and more “ stubborn†and the cards will get deeper and deeper in the pattern. When the tires wear to a certain extent, these foreign materials will even puncture the carcass, causing the tire to leak or even puncture the tire.
