Car tire safety knowledge

Don't say you only know Michelin restaurants

When the summer and autumn meet again, while the daily temperature gradually decreases, the difference in temperature between day and night has gradually widened.forcarIn other words, the parts that are most affected by temperature aretireNS.

tire, Is that the car is stationary and driving is the only part in contact with the ground. This consumable made of synthetic rubber is actually very delicate. Except for the solid tires of some racing cars and some "run-flat tires", the ordinary tires that everyone comes into contact with are all pneumatic tires.

An inflated tire can be regarded as a confined space. Using simple physical knowledge, Ray can explain to you why temperature changes affect the pressure value of the tire.

PV=nRT

P=nRT/V

If you assume that the tire volume is constant, you can see that the air pressure P is inversely proportional to the temperature T. This is why people often find that the low-pressure indicator in the dashboard of the car lights up when the weather suddenly drops.

Different tires are designed to cope with different road conditions and the needs of drivers. Those ordinary tires, Ray, are not mentioned.

"Four-season tires" can almost meet the changes in temperature and road conditions throughout the year, and the tire walls are relatively thick.

"Summer tires" have a better texture to fit dry roads, and the thickness of the tire wall is not as thick as that of "four season tires", and it wears relatively quickly.

"Snow tires", snow tires with very deep lines in order to obtain more friction and contact area with the ground, of course, they are also ugly, but more wear-resistant.

"Performance tires" are generally equipped as standard on top sports vehicles of major car brands in order to achieve the best sports and performance effects. Tires of this type are generally thin and very easy to wear.

[Inspection Method]

According to your own temperature and road environment, go to qualifiedcar maintenanceCheck or replace proper tires at the maintenance shop. Tires with thinner skins are not suitable for long-term driving on uneven roads, nor for high-speed driving on uneven roads.

3. Exceeding the tire's limit driving speed

The performance and use of different tires are not only related to the tire thickness and wear resistance mentioned above, but these tires also have upper speed limits.

The manufacturing and synthesis processes of different tires are linked to prices. The tires that pursue performance can withstand the test of high-speed driving, and the rough workmanship of those ordinary tires cannot cope with such speeds.

According to the above table, combined with the model and style of your car, it is very important to choose a tire that suits you.

The wheels of a car are something that makes people’s eyes brighter. Many friends will choose to replace them with better-looking ones.Wheel hubTo attract attention. But don’t forget that while replacing the better-looking wheels, you also need a set of better-performing or better-fitting tires to assist.

[Inspection Method]

According to this knowledge map, combined with the above table, learn the driving load capacity of your wheels.

Drag racing requires capital. Brother Ray doesn't know how capable you are to drive your car, but your tires are so capable. So I hope you recognize the safe driving speed of your vehicle and drive carefully.

4. Tire aging, wear, and damage

Back to the essence of car tires, because car tires are rubber products. Rubber is a substance that will naturally age, so even if it is not used, car tires will also age.

The life span of car tires is generally about 3 to 5 years. Tire aging is manifested in cracks and discoloration on the surface of the tire skin. These are the aging states that can be observed with the naked eye. Some other "tire vitality foams" on the market can temporarily rejuvenate tarnished tires, but they returned to their original state after a few days.

tireValveMost of the core is also made of rubber, and this part will also age like a tire. This part is not just a channel for pumping air. Once it starts to age, it is also the trigger point for your tires to leak and blow out.

Similarly, the texture of car tires will be worn to varying degrees after normal driving and intense driving. The more worn, the shallower the tire pattern, the thinner the tire wall, and the lower the friction with the ground. At this time, as long as it hits a sharp object at high speed, it will inevitably blow out, which is very dangerous!

Ray mentioned above that the sidewall of the tire is the thinnest part of the tire. Many friends will rub the "road duck" or press into the pit of the road during driving. The above situation will cause the sidewall of the tire to be impacted by high-speed friction, the internal structure of the tire will change, and the local rubber will lose its elasticity, resulting in the "bulging" phenomenon in the picture above.

Brother Ray reminds everyone, don't save money for a tire. Your safety and life are given to the tires. Do you have to wait for the tires to change into a sexy bag like the picture above?

Tire nails are very common, and tires can be repaired.However, every state has laws that require sharp objects to be inserted into the area where the tire is in contact with the ground to be repaired, and other areas must be replaced with new tires.

Finally, about "run-flat tires", Ray also wants to tell everyone.

"Explosion-proof tires" are not that they will not blow out, but that they can still drive the vehicle for a certain distance after a tire blowout occurs, ensuring that you can drive normally to the place where the tire can be replaced. Never rely on your own "explosion-proof tires" to continue driving unscrupulously at high speeds.

[Inspection Method]

Check the aging of the tire skin

Check the aging of the valve core

Check tire pattern and wear

Don't let the tire hurt and drive at high speed

How to deal with a flat tire

Regarding how to deal with and solve the situation of a flat tire correctly, Brother Ray made the above GIF picture in order to be lazy. Friends with normal IQ should understand it after reading it!

The video above is an accident that happened next to Ray.

The cause of the accident was that the wheels were worn too much and the tires were too thin.A tire puncture occurred when driving at high speed, and then the vehicle lost control. When the wheels had no grip, they slammed on them.brakeIt was useless, but fortunately, the owner was not injured. Because it is the tires that stop the car, not just the brakes.
