Vehicle owners need to know the secrets of tire protection during the severe cold season
Category:Tire maintenance - Date:2018-04-19
when winter comes, the ordinary road becomes hard and slippery through the cold and dry airflow, and the water will soon become a smooth ice surface. Such road conditions often appear rear end and steering out of control. On a snowy day or even a few days after the snow, the wet skate on the road and the stout ice after rolling and rolling will directly test the performance of the driver's and your car's tires. Here are the tips for the maintenance of the tire in winter.
In winter, in ice and snow road, the driving technology is only one aspect, and the performance of the whole vehicle and the choice of the tire are also important factors. Then, how should we protect the tires in winter?
The tire pressure should not be lowered intentionally. Some people tend to think that the tire pressure of the wheel should be lower in winter to increase the contact area of the tire and the ground, and it is considered that the friction will increase and be safer. In fact, this idea is no longer suitable for the present situation. Former Car the tire pressure is generally high, and it is correct to reduce the tire pressure in winter; but the normal tire pressure is low due to the need of comfort, and the tire will be easily damaged if the pressure is further reduced. Therefore, the tire of winter vehicle should be punched according to the standard.
each car has a corresponding tire pressure, which directly affects the performance and reflection of the tire, and affects the fuel consumption to a certain extent. In general, the tire pressure values of the front and rear doors will be displayed on the inside of the front door. This is the number you need to check regularly. Too high or too low tire pressure will affect the service life of the tire, but the most important thing is the grip. Excessive tire pressure will not only increase the risk of tire explosion, but also the middle part of the tire is exposed to the ground in the form of protruding, which reduces the obvious catch range of the whole car and can not provide enough friction to brake the vehicle at the time of emergency braking. The low tire pressure also makes the two sides of the tire contact with the ground so that the entire tread can not touch the ground. In addition to increasing the wear of the tire wall, it is also impossible to provide enough land for grabbing, which is no less dangerous than the high tire driving. And often wear the thinnest part of the tire wall will directly lead to premature scrap. It is better to use the tire pressure meter to check the four tire pressure every week to ensure that the front and rear tire surfaces are fully exposed to the ground to achieve the best ground effect, and also to reduce the vibration of the road, increase the driving comfort and fuel saving.
for a long time, the ice and snow road should be changed. Usually, the car manufacturers are all equipped with all weather car tires when the vehicle is out of the factory. This kind of tire is normally used to cope with common road conditions, so it is suitable for all seasons. But the performance is actually a compromise between the summer tire and winter tire characteristics, so in order to get excellent driving effect, we also need to use special tyres. For example, a specially developed &ldquo, a snowy tire &rdquo, has a very deep tread, but only in low temperature, ice and snow surface can show the advantage of good adhesion, so the long time ice and snow road can be replaced by “ snow tire ”
Daily inspection of tires and inspection on the way. No matter of any season, we can not ignore the daily maintenance of the tire, regularly check whether the tire is staple, cut, the valve mouth rubber aging, cracking and other phenomena, after discovery, timely repair or replacement, to prevent loss of gas.
in winter, the inclusions in the tread should be cleaned regularly, so that the hard debris can not be left in the tire stripe, causing the tire to break or deflate. In the course of the car, it is unavoidable to clip the foreign objects such as bastard stones in the tread, if it is not cleared in time, the time is long, some of them will fall off themselves, but a considerable part will become more and more “ the stubborn &rdquo is deeper and deeper, when the tire wear to a certain extent, these small stones even will Piercing the body, causing the tire to leak or even blowout. Try to avoid bulging foreign bodies rolled into nails, glass, dry and hard branches. The current family car is equipped with a radial tire when it comes out of the factory. Its airtight layer and the outer tire are tightly combined. There is no inner tube, so the gas inside the tire does not leak at a sudden, but slow to blow in the tire. However, when the pressure is reduced to a certain extent, the deformation on both sides of the tread will increase, the tire pattern is overly worn, and the body will eventually distort and distort due to the inability to resist excessive pressure. Finally, it leads to the blowout.
In winter, special attention should be paid to tire aging and pattern wear. If the tire is cracked or the pattern is seriously worn, the tire should be repaired in time. If the inside and outside wear of the tire is different, the tire can be replaced regularly. In addition, do not use different brands of different patterns of tires.
If you feel that the vehicle is tired, difficult to operate, the body tilt or the noise, jitter, and burning smell, should stop checking the tire condition immediately; check whether the tire pressure and temperature are normal, whether the tire nut is loose, or whether the tire is scratched or not, and see whether there is any sundries embedded between the tread or double tire. Enter, once found, it should be cleared in time.
Vehicle safety parked. Vehicle owners also need to pay special attention when parking vehicles, so that the valve can not be damaged by contacting hard objects outside, resulting in tire deflation. At the same time, the car owners often have valve cap to prevent debris from blocking. Under cold weather conditions, the vehicle is suspended in the field for a long time. In order to prevent the tyres from being cracked, the planks, branches and sand should be placed under the tire. The elasticity and toughness of the tires are all poor under the low temperature condition. After the start, the tire should run at a low speed, and then the tire will run at a normal speed after the tire temperature rises; if the start is higher, the tire should be running at a normal speed. Due to frequent deformation, tyres are liable to cause early damage.
Take care of the tire wall to check the depth of the tire texture. The wall of the tire is divided into the inner wall and the outer wall. General tire maintenance carefully check the side of the car facing the outside side of the car, and protect and maintain this side. But it only protects the side wall of the tire. In this way, no matter how to replace the 4 tire, only one side is protected while the other side is basically forgotten. As we all know, the tire wall is the most vulnerable part of the whole tire. Once the rubbing and scratching are basically caused by the blowout, it is generally possible to protect the outer part of the tire. But how many people are maintaining the inner wall of their tires, in fact, the test of the wall of this side is not only less than the outside, but on the contrary will be more hurt than the outside side. At high speed, the sharp surface of the bottom of the car under the wind pressure may cause the scratches directly to the inner tread. When you pay attention to the outside tyres, the inner wall may be directly damaged by sharp or rough objects inside the pit. So often your tire is still flawless when the outer side may be already scarred inside. In cold winter conditions, those scars may bring unexpected danger at any time. Every time after running the complex road surface and before and after the high speed, the vehicle is lifted to check whether the inner wall of the tire is injured. If you can't lift the car and turn the steering wheel to your head in a good weather condition, you can see the inside tire wall of the steering wheel directly.
do not belittle the patterns on the tires, each will appear on the tread after repeated testing and design. So pay attention to the details of tread pattern so that they can give you the most realistic feedback at the most needed time. If the tire has been running for more than 10000 kilometers, the tire tread should be carefully checked. If there is wear and tear, it should be made four rounds of positioning so that all tire tread can be evenly distributed to the ground. If we do four rounds of positioning and transposition on time, we should check whether there are any foreign objects in the pattern during each transposition, such as stones and sharp objects. This can prevent the tread from accidental piercing of the foreign body due to high speed or bump, and the uneven wear of the pattern on the ice and snow surface caused by uneven grip. In addition, after 50000 kilometers or 3 years, the tire tread pattern should be noted to reach the lower limit, or it has failed to meet the braking requirements. Generally, the new tire can have 5 to 7 points on the tire wall to show tire life. Once worn out, it will be prompted to change the tire. However, due to the fact that the tire is dirty and can not be displayed, the tire texture depth should be checked at the time of expiration, and the tire should be replaced if the tire is below 3 mm.
how to use antiskid chain correctly for snow and ice pavement
anti-skid chains are usually made of steel chains or rubber chains. The principle is simple, easy to install and practical.
the antiskid chain can be divided into two types according to the structure: one is a skid chain that has been covered with a cover; the other is a few separate antiskid chains that are cross installed. It is simpler and cheaper, but it is less convenient to install than the former.
In the use of antiskid chain, we should pay attention to the following aspects: it is best to make good antiskid chain before trip, and do not install it after ice and snow pavement, because the temporary installation of antiskid chain is more troublesome than early installation, and it is not good for safety. The vehicle must be parked in the safe zone before installation and demolition. If you are on a busy road, you need to set up the necessary traffic warning signs; do not install the skid chain in a flat tire; the skid chain also has a size limit. It is suitable for different wheel size and tire width. Pay attention to the antiskid chain that matches the wheel size; after installing a skid chain, the driving speed is generally not more than 50km/h. To avoid sudden acceleration or deceleration as far as possible.
The installation of antiskid chain should not be too loose or too tight to prevent the chain from damaging the tires directly; the antiskid chain is not designed for the trailer or tractor. After the difficult section, it should be dismantled immediately, and it is forbidden to use it on the hard road. In cold areas, some owners make their own chains, so that they can solve problems temporarily, but they are not worth promoting.
How to install (dismantling) skid chain in snow sky road slippery
installation and removal of the chain is a very fast process, even in cold weather. With 15 to 30min time, the vehicle can run safely and reliably in winter.
install and remove chains in relatively safe locations. When you install or dismantle the road, you must choose a safe and flat road to park alongside. Ensure that the car has been stopped to prevent accidents. Use wooden blocks to support tyres as additional protection measures to remove excess mud and snow on tyres. Make sure the car depends on the front wheel or rear wheel drive, because the chain must be hooked on the main driving tire. Remove the mud and snow around the tires as far as possible, revealing a flat surface. The chain is laid under the bottom of the wheel and the first gear on each chain connected to the ground is leaned against the tire. Make sure that the chain is covered with particles on the ground, which is the part of the chain that has the greatest traction.
if you are a rear wheel drive vehicle, you must tighten the chain backwards. If it's the front wheel, push it forward. Check to see if each tyre is secured to the chain, with a pair of gears on each side. Then get on the train, start the engine, slowly and carefully with the chain to move the car forward or backward about 2 feet. Once the tire is placed on the chain at right angles, the port that is lapped to the top of the tire is pulled off. Each end must be a device that perfectly fits the entire chain gear. First leave yourself 1 to 2 inches, and then tighten the device through the two sides of the chain link. Each rubber ring of the chain has 4 metal hooks evenly distributed around it. On the rim of the wheel, each metal hook is crisscross. This ensures that the chain will not slide. The chain has been fully installed and can provide traction on snow roads. However, do not think that the chain can guarantee the rapid driving in the harsh driving environment. Start slowly and pay attention to the sound of the car. It may be a reminder that the chain is loose or the tire is not installed. No matter how safe their use is, it will be unwise to chain the tyres at high speed. When it no longer snows, the chain on the car should be removed. No matter in any case, do not carry the chain on the road without snow, will seriously damage the tire. The disassembly of the chain is much simpler than the installation. Just do the opposite steps, unload the chain, and store them in a dry place for the next time.
