Seven taboos for car maintenance and use of tires

Statistics show that, in traffic accidents on expressways, the occupation rate of accidents caused by flat tires is more than 70%. This shows the importance of tires to vehicles. Today, I will talk to you about the seven taboos of using tires. I hope that all car owners and friends will pay more attention.
1. Avoid tire overload
The structure, strength, and operating pressure and speed of the tire are determined by the manufacturer’s strict calculations. If the tire does not comply with the standard and is overloaded, it will affect its service life. According to experiments conducted by relevant departments, the tire life will be reduced by 20% when the overload is 10%, and the rolling resistance of the tire will increase by 45%-60% when the overload is 30%, 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 signs and never exceed the maximum value. If the air pressure is too high, the weight of the car body will be concentrated on the center of the tread, causing the center of the tread to wear quickly. When impacted by external forces, it is easy to cause trauma or even blasting. The tread tension is too large, resulting in tread delamination and cracking of the tread groove bottom. The tire grip is reduced, the braking performance is reduced, the comfort is reduced, and the vehicle suspension system is easily damaged.
3. Avoid using the spare tire as a normal tire
During the use of the vehicle, if after running 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 undesirable. Because the use time is different, the tire aging degree is also different, so it is very unsafe. If the tire is broken on the road, car owners usually replace it with a spare tire. Some car owners don’t remember to replace the spare tire, forgetting that the spare tire is just “a tire in case.”
4. Avoid insufficient tire pressure
Insufficient tire pressure can cause the tire to overheat. Low pressure causes uneven ground contact area of ​​the tire, delamination of the tread or ply, cracks in the tread grooves and shoulders, broken cords, rapid wear of the shoulders, shortening the service life of the tire and increasing the distance between the bead and the rim The abnormal friction caused by the tire lip damage, or the tire is separated from the rim, or even a puncture will increase the rolling resistance, increase the fuel consumption, and affect the control of the vehicle, and even cause a traffic accident in severe cases.
5. Avoid judging tire pressure with the naked eye
On average, tires will lose 0.7 kg/cm² of air pressure every month, and tire air pressure changes with temperature. Every time the temperature rises/drops by 10°C, the air pressure also rises/drops 0.07~0.14kg/cm². The pressure must be within Measure when the tire is cold, and be sure to cover the valve cap after the measurement, and develop the habit of using a barometer to measure the air pressure, and do not judge by the naked eye.
6. Avoid inconsistent tire pressures
When the tire pressure on one side is too low, the vehicle will deflect to this side during driving and braking. At the same time, it should be noted that the two tires on the same axle should have exactly the same pattern specifications. Tires of different manufacturers and different patterns cannot be used on the two front wheels at the same time, otherwise there will be deviations.
7. Avoid not removing foreign bodies in tires in time
When a car is driving, the road surface is very different. The tread pattern will inevitably be mixed with foreign objects such as broken stones, nails, iron filings, glass shards, etc. If it is not removed in time, it will take a long time, and some of them will fall off by themselves, but there are A considerable part of them will become more and more “stubborn”, getting stuck in the pattern deeper and deeper. When the tire is worn to a certain extent, these foreign objects will even pierce the carcass, causing the tire to leak or even blow.
