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.

2013 global Auto Companies sales

Toyota Group is expected reelection highest car company in Laurel of Global car sales, nearly 10 million units sold last year ; General Motors and Volkswagen will occupy the other two seats in the top three, with the difference is extremely small, compared to 2012 while shortening the distance with Toyota.

November 2013, covering Toyota, Hino and Daihatsu three business department, the Toyota Group in November worldwide sales of 861,000 vehicles, compared with November 2012, an increase of 9.8%. 1-11 January, Toyota ‘s worldwide cumulative sales reached a new high of 9.093 million units, representing a slight rise of 1.8%.

In August 2013, Toyota announced production and marketing plan, its global sales target set last year to 9.96 million, compared to 9.748 million in 2012, an increase of 2.2%, but less than the earlier target by 10,000 vehicles. But according to the pre- November sales estimates, Toyota is likely to be higher than the annual sales target, the impact of 10 million mark. Japanese media said that if in December 2012 over the same period to maintain the level, then Toyota’s annual sales of 9.993 million.

Whether the target 9.96 million, or 9.993 million from media estimates, the Toyota Group ‘s sales have exceeded General Motors and Volkswagen Group.

General Motors recently announced that in the fourth quarter of 2013 achieved worldwide sales of 2,463,380 vehicles, compared with the fourth quarter of 2012 2,342,247 vehicles, an increase of 5.2 %. Last year, GM sold 9,714,652 vehicles worldwide, compared to 9,297,074 in 2012 (published figure was 9,285,991 last year ) vehicles, an increase of 4.5%.

According to the public data, if you do not include Mann and two commercial vehicle subsidiary of Scania, Volkswagen Group in December 2013 global sales of 833,200 units, compared to December 2012 ‘s 784,100 vehicles, an increase of 6.3 %. Last year, the Volkswagen Group’s global light vehicle sales of 9.5 million delivery, compared with 9.3 million in 2012, representing a rise of 4.8%.

Since the Volkswagen data is not accurate, the current media temporarily finds GM slightly beyond Volkswagen, ranked second in the sales charts last year. Volkswagen is expected to release exact sales figures when publish the 2013 financial data.

Cadillac 2013 sales up 67% in China

Cadillac sales in the Chinese market is growing rapidly , over half of last year, an increase of more than one month . 2013 full year , Cadillac sales in China to 50,005 , compared to 30,010 in 2012 , a sharp rise of 66.6% year on year , reaching a record annual sales record.

Cadillac SRX continues to be its most popular models , which sold 26,897 , 2012 sales of 21,698 , an increase of 24.0%. Cadillac XTS in the first year after listing sales reached 20,101 units. In addition, in November last year, just listed Cadillac ATS year sales of 2,154 units.

Last year, the Cadillac brand has started in Shanghai GM Jinqiao plant production. Prior to 2016 , the brand will add a model in China every year . By the end of 2013 , Cadillac dealership in China has increased from 69 at the end of 2011, around 200 .

Former General Motors CEO Exxon has said Cadillac sales in China to the United States will eventually emulate . Shanghai GM made Cadillac brand will achieve the “Double Ten ” strategy, which exceeded 10 million units by 2015, annual sales in China to achieve a 10% share of the luxury car market in 2020 . According to some institutions are expected in 2020 China sales of 2.7 million in luxury cars , Cadillac sales in China are expected when more than 250,000 .

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.
