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.

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.

Xi shows common touch with visit to bun eatery

Chinese President Xi Jinping showed off the common touch on Saturday with a surprise visit to a steamed bun restaurant in Beijing where he paid for his food and happily chatted to surprised customers.

In pictures widely shared on China’s Twitter-like microblogging service Sina Weibo, and confirmed by state media, Xi could be seen lining up for his food and posing for photographs, apparently not surrounded by the high security which normally accompanies visits by top leaders.

While such interactions are considered run-of-the-mill in Western countries, they are highly unusual for senior Chinese officials.

Since coming to power as party head in November and president in March, Xi has demanded officials cut down on waste and extravagance and get closer to the people, as part of a broader campaign to root out corruption.

State media said that Xi’s meal of steamed buns, fried liver and stir-fired greens cost 21 yuan ($3.46).

“Uncle Xi is showing that he is one of the people. I approve,” wrote one Weibo user. (Source: China Daily)
