Someone will tire analogy people wear shoes, this is OK, but not heard of the sole burst can kill the story, and the tyre burst resulting in fatal car crash news is heard. Statistical data show that in the highway accidents, more than 70% of the accidents caused by the tire burst. From this point of view, the importance of tires to vehicles far exceeds the importance of shoes to people.
And users in the trip to go only to the engine, brakes, steering, lights and other checks and maintenance, but ignored the tire inspection and maintenance, so doing the driving safety buried a certain hidden danger. This article summarizes ten major taboos in the use of tyres, hoping to provide some help for your car life.
1, avoid tire pressure is too high.
Every car manufacturer has special rules for tyre pressure. Please follow the sign and never exceed the maximum. When the pressure is too high, the weight of the car body is concentrated in the center of the tread, leading to rapid wear of the tread center. By the external shock, prone to trauma or blasting tread; the tension is too large, causing the tread delamination and tread groove cracking; tire grip decreases, reduce vehicle braking performance; beating, reduced comfort, easy to damage the vehicle suspension system.
2, avoid tire pressure is insufficient.
A low tire pressure can cause overheating of the tires. Low pressure to the tire contact area is not uniform, or tread ply delamination, tread grooves and shoulder cracking, cord fracture, shoulder wear quickly, shorten the service life of the tire; increase the abnormal friction between the tyre and rim, caused by tyre damage, or tire and wheel rim detachment. Even at the same time will increase the rolling resistance of tire; and increase fuel consumption, but also affects the vehicle’s handling, even when serious traffic accidents.
3, bogey with the naked eye to determine tire pressure.
The tire pressure will lose a monthly average of 0.7 kg / cm2, and tire pressure changes with temperature changes, the temperature drop per liter / 10 DEG C, the pressure will drop 0.07~0.14 liters / kg / cm2; air pressure in the tire cooling must be measured, and the measurement of fail after valve cap. Please form the habit of using barometer to measure barometric pressure. Don’t judge by naked eye. Sometimes the air pressure runs a lot, but the northern part of Baotou runs loose, but the tires don’t look too flat. Check air pressure (including spare wheel) at least once a month.
4, avoid the tire as a normal tire use.
Vehicles in use, if you run 100 thousand to 80 thousand kilometers later, the user will use the spare tire as a good tire, the original tire as a spare tire use, this is absolutely undesirable. Because the use of time is different, the tire aging degree is not the same, so it is very unsafe.
Tires are bad on the road, the owners will generally change the spare tire, and some owners do not remember, but also to change the spare tire, forget the spare tire is only “in case” tires”.
5, avoid around tire pressure inconsistent.
When the tire pressure on the side of the northern part of Baotou is too low, the vehicle will turn to the side in the course of running and braking. At the same time, we should also note that the same axle on the two tires should be of the same pattern specifications, different manufacturers, different patterns of tires can not be used at the same time two front wheels, otherwise there will be deviation phenomenon.
6, avoid tire overload work.
The structure, strength, and pressure and speed of the tire are determined by the manufacturer’s strict calculations. The tire does not conform to the standard, and the overloaded tires will affect its service life. According to the relevant departments of the experiment proved: overload 10%, tire life decreased by 20%; overload 30%, tire rolling resistance will increase by 45%-60%, while the fuel consumption will increase.
At the same time, overloading itself is strictly prohibited by the law.
7, avoid timely removal of foreign tires.
When a car is running, running pavement vary, inevitably clamp nails, stones, foreign offal iron and glass pieces tread, if not removed, a long time, some of them will fall off, but there are quite a few more “stubborn”, stuck in the sink deeper pattern deep, when the tire wear to a certain extent, these foreign bodies may even lead to a flat tire punctured tire, or blowout.
8, avoid the spare tire will not be careless with.
The main component of the tire is rubber, and rubber is the most afraid of all kinds of oil erosion, tires stained with oil, will soon be swelling corrosion, which will greatly reduce the service life of tires. So try not to put the oil and the spare tire together. If the spare tire has been stained with oil, be sure to use a neutral detergent to flush off the grease.
Don’t forget to check the spare tire every time you check the tire pressure. And the pressure of the spare tire should be relatively high, so as not to run away.
9, avoid tire pressure unchanged.
Usually when driving on the highway, tire pressure should be increased by 10%, to reduce the heat generated by flex, thereby improving the driving safety.
Winter should also appropriately increase the tire pressure. In winter, when the outdoor temperature is low, the tire pressure will be reduced by the influence of thermal expansion and cold contraction. If the tire pressure is not properly increased, it will not only increase the fuel consumption of automobiles, but also accelerate the wear of automobile tires. But also can not be too high, otherwise it will greatly reduce the northern part of Baotou running loose parts, tires and ground friction, brake performance weakened.
10, avoid repairing the tires, do not pay attention to.
Repaired tires should not be installed on the front wheel or on the motorway for long periods of time. When the tire is damaged, because the sidewall is thin and is used in the deformation area of the tire, tire pressure of the circumferential force is large, it should replace the tire.
