Q: What are the functions of automobile tires?: The modern automobile speed continues to improve, the temperature rise in high speed rolling tire under internal friction intensifies, and will make the physical and mechanical properties of tire materials decreased, at the same time caused by dynamic load increases, working conditions deteriorate, so special requirements of tire safety and reliability in high speed condition, low rolling resistance, long service life, to ensure the safety of and the economy car. The above requirements are often contradictory. Such as large load, tread fast wear, short life; soft and comfortable tires, traction capacity is poor; reduce rolling resistance, fuel saving effect, but the handling stability is poor. According to the Chongqing auto parts industry, the progress of tire technology is focused on resolving these contradictions, so that the structure, material and manufacturing technology of tires have been continuously improved and improved.

Q: Do you have to change the tires to the safety line?: In addition, the damaged tire should also pay attention to measure whether the need to be replaced, such as the lack of gas after rolling the tire while still running in the inflated state, but due to the internal structure of the tire may have been damaged, so that timely replacement of fetal. Special need to remind is that drum wrapped tires shall not continue to use.

Q: What are the properties of the tires? What's the effect?: Anti skid, drainage, wading, heat dissipation, steering, stationary......Heat dissipation: it requires good ventilation and heat dissipation, so that the braking effect and safety factor of the car will not be affected.Skid resistance: in different road conditions, the tire tread will not be affected too much, such as sand, cross roads, loose roads, etc.Wading: in rainy days, the tire pattern is deeper, in the water, the road better drainage, to ensure the braking of the car.Steering: it's required for the differential part of the car. This is not just the performance requirements of the tires, it's part of the chassis

Q: The Great Wall pickup holds 1 tons of cargo. How much is the tire pressure?: The Great Wall pickup tire pressure is:Empty tire pressure, front wheel 2.5--3, rear wheel 3-3.5, heavy load front wheel 3.5, rear wheel 4.

Q: How to identify the specifications of car tires?: The tire specifications are usually represented by a set of figures. The first figure represents the width of the section of the tire, and the latter represents the diameter of the rim, in inches. For example, 165 / 70R14 represents a tyre width of 165 mm, a flat rate of 70, and a radial tire of 14 inches in diameter. Some tires also contain other letters or symbols that have a special meaning: "X" means a high-pressure tire; "C" indicates an enhanced type; "B" indicates an oblique tire; "1" represents a low-pressure tire. M and S are abbreviations in English, Mud and Snow, which indicate that this kind of tire is suitable for use on ice and muddy roads. Some tires have an arrow or OUTER SIDE on the wall, which indicates the direction of the wheel's rotation. If a small umbrella sign is painted on the tire wall, it shows that the tire is suitable for traveling on rainy or slippery roads. The DOT mark indicates that the tire has passed the certification of the United States and Canada * * * transport department. Behind the DOT mark is usually followed by a 4 digit number, and unlike other text, it is not an early die, but it is later pressed on the tire, such as (0518), which means the date of production of the tire.

Q: Does anyone know what brand of big truck is used in the market now?: Bridgestone, HANKOOK and Giti with the most, which is accounted for the largest proportion of HANKOOK tire

Q: How to identify refurbished tires?: From the point of view of texture, usually, because innovation is not defective tire processing standard, so the relatively shallow groove. In color, the defective tire looks colorful innovation, shiny shiny, standard relatively dark.

Q: The car tires have been in use for 4 years! Do I need to replace it?: The use of tires generally do not exceed 4 years, mileage is not more than 60 thousand kilometers. Although slightly longer than the length of life and mileage is no harm to the overall situation, but the winter low temperature and summer rain will make the tires of wetland grip and dry ground manipulation "stretched""

Q: What's the use of car tyres?: In 1895, with the advent of the automobile, the development of pneumatic tires widely, the first tire sample is 1895 appeared in France, this is the single type tire made of plain canvas, although there is no pattern tread. Until 1908 to 1912, the tires have changed dramatically, the tread has increased the performance of the pattern, so as to exploit the tread pattern of history, and to increase the section width of the tire, allowing the use of low pressure, in order to guarantee good cushioning properties.
