Car Tire maintenance

The blowout accident, there are many because of tire aging not timely replacement caused by. The rubber as the raw material of tire storage there is life after aging, elasticity and toughness will be greatly reduced, service life longer burst probability is higher. According to the official statement tire manufacturers, general tire life ought to be in 2 years or 6-8 million km intervals.

In order to avoid tire blowout accident caused by aging, we should understand the car tire production period, and the last change date, at the same time, to understand the life of the tire, so as to achieve the heart spectrum. We learn from the professional, if you use is not frequent, and the car environment is not bad, it is best to have a garage can ensure the temperature relatively small, general tire normal use of 4-5 years is not a problem, of course, the premise is frequently check, as small as possible. The use of love.

In addition to the rolling wear normal, and is part of the other external injury, parking in the crowded city sometimes need on the curb, in the outskirts of poor road conditions, rolling stones will make the tire from excessive wear local, this is inevitable. So in the normal driving, develop around the car a week habit, have a look the tire has no trauma, if it is found that the bulge phenomenon or injury shall timely treatment or replacement.

The tire side is the place where the tire the weakest, and we in the parking time, especially when the stop on the road if not available easily tire side and rubbed in the course of time will make on the curb, sidewall becomes thinner, resulting in burst a tire is leaking or running.

Tire pressure is not correct is triggered an important reason of blowout. Maximum tire each tire will indicate the tire can bear on the side are the pressure value, if the initial inflation pressure is close to the maximum pressure value, then the hot weather and high speed, tire pressure will rise even more than the maximum pressure value, burst is inevitable.

But if the tire pressure is too low, the tire sidewall ply can withstand pressure pressure greater than the standard, if the long-term pneumatic driving, rubber and cord ply are serious deformation, increase the wear and aging, in this case in the relatively poor roads or large external shocks, then the tire will the irregular deformation, internal cord will cause the cord rapid temperature rise caused by continuous deformation, fatigue, fracture is the consequence of tire cord.

Suggested that the majority of drivers to develop good habits of self check tire pressure, there are a lot of related products on the market, from simple to complex, there are many kinds of. But at least you should prepare a simple tire pressure table, every 1 months check 4 tire pressure, the price is not expensive, is not very troublesome, but can achieve the basic mind. Good maintenance play an important role in car,but you also can find some hot car tools like T300 Key Programmer and Tacho Pro 2008 to help you solve the car problems.

Automotive glass development / knowledge introduction

With the development of automobile and mechanical properties, the speed becomes more and more fast, fierce wind and flying debris into a very serious problem in the driver’s face. In order to reduce the trouble, the twenty’s of last century, various automobile manufacturers with a piece of glass in the car. These initial windshield by flat glass hand cut, but unfortunately when the glass broken, sharp splinters of flat glass will be broken into a large dangerous, and injury to the occupant, which do not meet the windshield installation for safety purpose.

The use of the automobile glass are mainly two types of material, laminated glass and tempered glass. Laminated glass is two layers of glass with a layer of gelatinous membrane overlap between, cannot split completely in the event of damage fracture and diffusion. Even if the occurrence of serious impact, relying on intermediate adhesive film can also be damaged under the circumstances to ensure glass does not fall off and some scattered, remained relatively integrity. Because of this characteristic, in order to ensure the implementation and safety driver set aside to complete in the presence of impact, laminated glass is provided in the front windshield.

Toughened glass in damaged, can spread rapidly into numerous small particles, and it is easy to fall off, in the critical moment can easily escape, and the car side and back by the stone hit probability than the front windshield, therefore, toughened glass is widely used in addition to other parts of the front windshield.

At present, in the use of the car front are laminated glass, cracks can be repaired. In addition to the front, around the window glass is damaged because they would spread quickly and fell off, and therefore can not be repaired. In addition, there are some high-end models used in the side windows of the double-layer tempered glass, in ensuring the safety and also to the greatest degree of mute.

Later in the vehicle development process, the inventors and engineers together, through various kinds of high precision technology, endowed with more powerful function for automotive glass. Below we introduce several of them:

1, the HUD display technology, can be in the front vehicle information, vehicle display glass, such as speed, engine speed, oil etc..
2, clean glass, is through the installation of ionization device on the glass, to avoid the dust absorption in the glass;
3, water repellent glass, the glass surface after fluoride treatment in particular, rain on the glass will condense into water droplets fall, no water stains, see clearly, which can help the driver to make correct judgment;
4, plus nitrogen glass, the glass per square millimeter can withstand the pressure of 1200 kg, even when the car is being hit by a piece of metal at 200 kilometers per hour speed, also can not be broken down.

The window broken more common for glass crack caused by stones and other hard object impact front, initially appeared in these crack point, can be repaired in some professional glass beauty shop, but this type of repair technique for crack area requirement is very high, about one or two cm above the broken area can not repair, can only choose the replacement of glass.

Usually, glass breakage, repair personnel will be made as soon as possible repair, many friends will ask, since the wound has emerged, simply do open, have time to repair. Actually this kind of practice is not correct, with the change of temperature in a day, deformation and heat the cold will cause the glass, and continue to run the drag will further erode the breakage, to bring pressure on it continuously damaged, may be enlarged, if missed the best repair area, may repair the effect will be greatly reduced, so that the window is broken, should be the first time to repair.

Discussion on various tread patterns

As the only medium vehicle tire, contact with the ground, shouldering the important responsibility bearing, brake and driving safety. While the vehicle is moving in a normal road, tire real contact area with the ground, never than we walk on the road of sole and the ground contact area of much. The contact area is so small, need to complete the above so many important and complex work, then the pattern on the tire plays a crucial role in.

Generally speaking, the tire tread or tire tread on a variety of longitudinal, transverse, oblique consisting of trench. Don’t look at those across the vertical pattern is a mess, but they can have a clear division of labor. Longitudinal patterns as features has vertical continuity, so the main bear rain drainage function, and for tire cooling is also very helpful, but lack of grip. Lateral pattern has a greater ability to grip, congenital defects which can compensate for the longitudinal pattern.

Design of an ordinary civilian tire requires comprehensive consideration, not only to meet the sunny dry running, but also to meet the rainy wetland running, can be said to a year four seasons climate characteristics are taken into account, so that ordinary users can not see the weather often go to change a tire.

Longitudinal tire tread on the main played fast drainage effect, but it will cause the tire grip ability is insufficient; the transverse pattern on the tire has a high ability to grip, but the drainage capacity and guidance is not good. Therefore the design of tire engineers will be two kinds of patterns mix together and reached a “tacit understanding”, let the middle transverse patterns to provide a rapid drainage of the longitudinal pattern and shoulder to provide grip with a perfect situation, so that mixed pattern was born. At present this mixture of tire tread pattern is widely used in cars, buses, trucks and other large numbers of vehicles, is one of the most worry choice.

Asymmetric patterns that both sides have different pattern structure. Because of the left and right pattern structure is different, so usually the design will pay more attention to the design of lateral pressure increases when turning the tread pattern. This is why the asymmetric tire in some cases cornering performance will cause relatively great. And considering the daily use, wear resistance of tire lateral asymmetry patterns can also be a corresponding increase in.

Not only that, because the two sides of the pattern with different structure and rubber formula, so the overall performance of tire can be stronger and more comprehensive, such as side pattern could focus on the drainage capacity, while the pattern could focus on the grip etc.. The asymmetric tire has been widely used, and has made the market definitely, is the majority of the owners to buy when the tire is preferred.

Note that because the tire inside and outside pattern is different, the installation must determine the correct tire. When using this pattern of the tire in tire on no special requirements, all around, as long as the main tire and can.

The mutual connection between single direction of the tire tread groove, have a road performance strong and drainage ability strong. The pattern of the tire rolling direction fixed, that is to say that the tire can be running in a direction, so that the advantages of tire rolling resistance will be relatively small, the vehicle handling more outstanding. But also because of this design single guide tires not about the same side only tire swap, that’s why it’s called the single oriented tire.

The single oriented pattern are all in one direction, and the mole larger pattern, crosscutting pattern and other small features. These characteristics determine the single oriented tire rolling resistance, control performance, performance advantage. The single oriented tire has a strong grip and drainage performance, and speed levels can be very high, the directivity and the control performance and can satisfy the demanding fancier.

Good maintenance play an important role in car,but you also can find some hot car tools like MB Star C3 and Digiprog III to help you solve the car problems.

Don’t ignore the vehicle inspection in winter

Recently, the cooler weather, the minimum temperature of the northern part of China has been close to 0 degrees Celsius or even lower, here need to remind owners promptly to the car remained in the glass of water to check, if the area low temperature has to be changed into the antifreeze glass of water, so as to avoid the cracking kettle glass or pipeline etc.. If your car you determine the residual in the glass of water, the best way is to get them out, then replace the antifreeze glass of water. Of course, if the residual is not too much, can also direct the antifreeze glass of water into the mixed use, can also play a certain effect of anti freezing.

If found to have obvious coagulation performance glass water spouts some difficulties or when the glass of water jet, the glass of water has frozen or frozen, then do not press the eject button glass water, avoid burning out the glass of water injection device. If you use a glass of water, recommendations on temperature for a period of time the standby cabin rose after the try out, also can be to glass kettle blending some hot water to open completely after ejection.

Summer and autumn rainfall, so during the wiper used very frequently. Plus rain, gum, guano and relatively inferior glass water interaction, can let the rain wiper blade earlier damage, affect the use. After the winter cold weather will accelerate the aging of rubber rain wiper blade, led directly to the cleaning effect of the glass windshield variation, affecting driving safety. So before winter can check their own work effect of rain wiper blade, when the aging or is unable to achieve the cleaning effect, can consider replacing.

With the decrease of temperature, tire rubber is easy to harden, compared to the summer more prone to cracking and to accelerate the aging, so before winter tires to conduct a comprehensive inspection. When it is discovered that the scars or serious aging, it is recommended to the professional repair shop for advice, when necessary, suggested a direct replacement. Also on the different seasons tire pressure adjustment views are different, we learn from the professional to, as long as the standard fetal instructions marked on the pressure value of tire, the car without deliberately adjusted higher or lower tire pressure.

So if you want to do more on cars, you can find some car tools as X431 Diagun III and T300 Key Programmer to get started.

Cooler autumn weather, the temperature will be lower in foggy, in this season, you should pay special attention to cream outlet wind is normal except windshield glass, heat enough, if there is a problem, to solve, otherwise, will bring unsafe factors to your driving. Similar to tire of the truth, the cooler weather can cause the belt to accelerated aging, aging serious belt because of toughness, easy to loose, slipping, so to check the belt carefully in the winter before. But checking belt general to carry out with the help of a professional, once found the aging damage, need to develop the habit of regular and relatively frequent habit of checking, serious when shall timely replacement.

A detailed interpretation of vehicle inspection process

Vehicle inspection time is divided into the following situations (motor vehicles shall be from the registration date): operating passenger cars within 5 years of each test 1 times; more than 5 years, to test 1 times every 6 months; truck and large, medium-sized non operating passenger cars within 10 years of each test 1 times more than 10 years; 1, inspection once every 6 months; small, micro non operating passenger cars 6 years testing every 2 years 1; more than 6 years, the annual inspection of 1; more than 15 years, to test 1 times every 6 months.

Carry things to prepare inspection:. The owner or agent ID; vehicle; cross strong insurance and other insurance documents. Insurance and the original must be within the period of validity. Many friends in the insurance expires and the testing maturity is a time, while in the insurance expires before the new year’s insurance, the inspection old age insurance has not expired, the new insurance has not yet entered into force, so be sure to bring is still within the validity period of the original insurance policy, also is the old policy to check, otherwise non effective insurance cannot be detected by, of course these only for compulsory insurance, compulsory insurance is the necessary examination, commercial insurance temporarily can not.

There is to look, illegal there was no untreated own vehicle, if anything should go to the DMV or industrial and Commercial Bank of China to handle all illegal record after inspection, or is unable to carry out testing. Vehicle detection field office Monday to Friday, there are some detection field Saturday office. The detection time: 8:00-12:00 am, 13:00-17:00 PM, the detection field at 12:00-13:00 is not the office, so I suggest you try to stagger on this period of time, it can avoid the waste of one hour.

Arrive at the test site, the first step is the appearance of test, the owners need to park the vehicle in the special inspection the appearance of the site, the fire extinguisher in the vehicle and triangle warning board ready, and the engine compartment of vehicles and the trunk open, waiting for the personnel of the inspection. In the visual inspection, the staff will take two forms, respectively is the motor vehicle inspection records of qualified certificate and the motor vehicle safety and technical inspection (some detection field is the need for the owner himself two copies of the form to the business hall). The staff will check and record the vehicle chassis number, engine number and other data, but also check the safety device warning triangle and fire extinguishers are complete. When the staff check the appearance of qualified, will be in the form of appearance that a signature.

Visual inspection of the need to pay attention to is, safety warning triangle and fire extinguisher that is complete, and the car color, appearance and the driving license of photo consistent. Now many young people like to post some personality logo in your car, it is not through in the vehicle inspection, the owner should take the car clean, only through appearance inspection. But there are exceptions, “practice” standard after the public security organ for approval of the legitimate car is allowed. If you bought a new car will not immediately put on his love note paper, need to paste again in the registration completed.

The air conditioning filter function

Deviation refers to the flat road, the vehicle will appear to the left or right running trend. To test whether the deviation try repeatedly in a plurality of flat ground, gently touching the steering wheel, if feel to the steering wheel was dragged the hand feeling is deviation. Here a little attention to, under normal circumstances, the right way is relatively low, the steering wheel without holding (SA), some vehicle always drive to the right, this phenomenon is normal without checking.

Pressure on both sides of the vehicle tire imbalance will lead directly to the vehicle running deviation. The principle is very simple, on both sides of tire pressure is not average, they touch the ground area is different, in the normal road tire friction, low air pressure is greater, so in this case, the vehicle will appear deviation side to pneumatic tire. If it is found that the deviation, first proposed or look at both sides of the tire pressure is normal.

Brake system problems. A slight right deviation in running time, the phenomenon is more obvious when the brake. Check the vehicle after the discovery of the right front brake branch pump problems, caused the brake pad can not return, the equivalent of the right front wheel has been slight brake state, resulting in deviation. Encountered a similar situation friend also beware of brake cylinder and two side brake wear is uniform.

The running time of vehicles, four wheel positioning data will lead to the emergence of the phenomenon of deviation. Especially often go to eliminate the road and vehicle on the curb, four wheel positioning parameters are easier to change. Because of the change of the main parts of the chassis can cause the deviation problem, this may be due to the daily traffic caused by wear and aging, may also be due to accidents caused by deformation of lead frame. The problem of Aging said, if the lower arm and other components has changed or is the gap is too large, adjustment or replacement parts can be solved; and if it is because the body caused by the accident, frame deformation damage problem caused by the deviation, is more serious, need a large area replacement parts even for frame correction is possible complete recovery.

The weight of the vehicle is not average will also cause the vehicle deviation, here is the main said often pull a heavy load truck, special attention should be paid to the goods placed evenly around. If the weight often rely on the side of the display, which may lead to problems: 1, because the center of gravity problems directly lead to the vehicle deviation; 2, even if there was no deviation occurs, often about placing uneven may lead to tire around wear is not the average, in the course of time will also because of tire friction force caused by the asymmetry deviation.

On the vehicle deviation, but also not too complicated, the most simple is left and right sides imbalance, including pressure imbalance, suspension supporting force unbalance, four wheel positioning is not balanced, the brake system is not balance, we should send these imbalances adjusted back to, let the wheel back on track otherwise, the long-term vehicle driving deviation may not wear balance due to the important parts of tires and so on, bring more security hidden danger.
