Black tires seem to be the least car parts for most car owners, but even the best car can't run away from these four wheels. Needless to say, the importance of tires, but how much do you know about the common sense of such critical parts? China international tire expo introduces you to:
Impact of excessive tire pressure on driving
Excessive tire pressure will not only cause puncture during high-speed driving, but also normal driving will be disturbed. The first is that the tire noise becomes larger; the second is that when passing through some undulating roads, the body will jump too frequently and the comfort will be reduced; in addition, excessive air pressure may make the steering feel lighter, but when the wheel is turning The lateral grip will be significantly reduced, causing understeer earlier and causing danger; the most important thing is that excessive tire pressure will also affect the braking effect of the vehicle. As the grounding area of the tire becomes smaller, the low attachment The emergency braking on the road will make the braking distance longer.
Impact of low tire pressure on driving
If the tire pressure is too low, the hidden danger also exists. First, the tire noise will turn into low-frequency noise, and the occupants may mistakenly think that the tire noise has become lower. If it is measured by its practical instrument, you will find that the noise index is still the same; then the driver can directly feel that the weight of the steering wheel has become heavy. The response speed of the front also becomes sluggish when driving in the direction, and understeer is also prone to occur when cornering quickly; the only benefit is that the comfort will be slightly improved, and the body's sway will be weakened when driving over bumpy roads. But to remind you, this is in exchange for high fuel consumption and sacrifice of safety.
The correct method of tire pressure detection
So how to determine whether the air pressure of an affordable tire is appropriate? In general, the required inflation pressure of the tire is clearly marked in the manual of the car. Mercedes-Benz truck parts manufacturers need to remind you not to believe what you see, because most of our cars are now equipped with low-pressure radial tires without inner tubes. Sometimes they will feel a little flat from the outside, but it does not mean that they will be deflated. Standard instruments are the only means of detecting whether the air pressure is normal or not. When detecting tire pressure, it must be under the condition of cold tires. If it is a hot tire measurement, the measured value must be reduced by 0.3Pa to be accurate. Now tire pressure gauges are available in any tire store or auto parts city.
Judgment of tread pattern wear
Tire show believes that in addition to tire pressure, the tread pattern also requires us to check frequently. Genuine tires are marked with wear limits on the sidewalls before leaving the factory. If there is no such mark, we can also use calipers. Generally, tires with a groove depth of less than 1.6 mm cannot be used anymore, because Mercedes-Benz truck parts tires Drainage performance and anti-stab performance have been greatly reduced. In addition, if a tire has been repaired three or four times, then we recommend that you better replace this tire with non-driving wheels or rear wheels to reduce the risk of flat tires.
Several signs of tire damage
Whether it is a car or a tire, there will be signs before a major failure occurs, and you must be extra careful when your vehicle is running off, the tire noise becomes larger, the high-speed abnormal jitter, or the tread has bulging. Because it is very likely that your car is on the verge of danger, you should repair or replace the tires in time.
