90 Enhanced light truck tires pass checks

AQSIQ for enhanced light truck tire inflated tire inner tubes and product quality supervision and spot checks carried out the country. A total of 22 samples of the products, 20 kinds of qualified, product sampling with a pass rate of 90.9 percent.

The spot checks in the main problem is that the quality of the project elongation at break-standard requirements of the valve pad and child bonding strength of the project are not up to standard.

5 produced the enhanced light truck tire inflated tire inner tubes and a better quality: Triangle Tire Co., Ltd. (Shandong), Shandong Chengshan Tire Co., Ltd., Aeolus Tire Co., Ltd. (Henan), Guizhou Tire Company Limited , Double Happiness Tire Industrial Co., Ltd. (Shanxi).

Enhanced light truck tire inflated tire inner tubes and small product knowledge

Traffic safety, economy and comfort, and so on, with the reliability of the tires, rolling resistance, and adhesion properties of the relevant buffer. Therefore, a variety of models fitted with the tire specifications, there are strict rules in general.

1, in replacement of the original car tire, the tire chosen not only match the specifications, but also pay attention to tire of the structure, hierarchy, the type of pattern and so on. At the same time, vehicle replacement tires for easy, but they increase the cost. In the use of replacement tires one by one the way to replace the original vehicle tires, more attention should be matched: the same tire outside diameter, the same level, the same pattern. On the local, round about the performance of front axle, brake and easily lead to the direction of deviation; file inside and outside the rear axle tire outside diameter, easy to overload caused by a single child, and so on.

2, tire assembly, in the car of the same axis to achieve "unity of the eight" that is "eight":

(1) the same specifications: the specifications of different tire inflated and the outside diameter of a wide cross-section do not like to put on the same axis load distribution is not the same, it must be asked the same axis with the specifications. In addition, before and after the shaft did not specifically require the vehicles, the tire specifications should be the same.

(2) the same structure: radial cord matrix arranged perpendicular to the rim, the radial deformation, the buffer performance, compared belt as hard tank track, the weeks to small deformation, rolling tires a week close to the length of the outer perimeter. The bias tire is different radial deformation of the small, poor performance of the buffer, the moving parts of the ground contacts have been compressed, the deformation of the week, to less than a week away from the outer circumference of the tire. Two tires mixed in the same axis, does not necessarily bear the load, wear uniform. As a result, the same shaft assembly must be the same structure of the tire.

(3) of the same material: mainly refers to the cord matrix material. For example: all-steel radial tire with the fiber, and so on, the thickness of the matrix, the cord strength, heat dissipation, and so have a greater difference, with mixed results will be affected. As a result, the same axis of tire cord matrix material (known as the professional framework matrix materials) must be the same.

(4) the same level: the level of the tire is a load-level, at the same time to determine the appropriate standard atmospheric pressure, the load capacity of different tires mixed with air pressure different tire deformation is also different. Therefore the same axis must be the same level, to ensure that the fetal position LOAD line.

(5) the same pattern: different tread patterns, not only wear a difference, and on the ground and the adhesion is not the same. Automobile tires around different patterns (such as vertical and horizontal axis in the same pattern installed), will affect the vehicle's ride, the emergency brake when there are unilateral and tail phenomenon.

(6) the same brand: manufacturer, the outline of the tire size, tread width, the pattern shape, have a cord material difference. Different brands of tires mixed together will also affect the results. As a result, the same axis must be the same brand. Only in this way can play a proper tire and vehicle performance.

(7), the same pressure: the pressure levels. Should maintain the same level of pressure, to maintain identity. As a result, the same axis must be the same as atmospheric pressure.

(8) the same load: the load and pressure levels may be, should be based on the use of terms such as loading, compatibility with a load capacity of the tire to the same capacity, you can extend tire life. As a result, the same axis with the load. 10.00R2016PR to the all-steel radial tire, for example, national standards it clear that, where air pressure is 850kpa, for the carrying capacity of 3150kg; and when the pressure is 770kpa, the tire load capacity of 2800kg, the above-mentioned provisions clearly indicate that the The level of air pressure and determine the carrying capacity of the tire.

In the specific vehicle driving conditions, the tire has special requirements. Through the use of tires, repair, renovation, the decrease in performance can only be used to adapt to certain conditions, which must be between matching. For example, better tires should be assembled in front of vehicles or long-distance transport, often in a row, vehicles, it has a high traffic safety; used tires, the vehicle rear axle assembly; by the repair, renovation The defective tires or tire assembly should be in the short-distance transportation, moving slowly, carrying a lighter rear axle of the vehicle; often in the soft muddy roads, the assembly should be horizontal pattern and the rest of the tire tread to prevent slipping deeper; often Covered with stones, a hard object on the road, space travel, the rear axle of assembly proposal used tire repair or renovation of the tires in order to reduce the Spurs bar scratch the losses caused by tire; summer high temperature, warming up tires, Vehicle, rear axle assembly should be good tires to prevent tire temperature; low winter temperatures, heating up a small tire can be a little sub-assembly of the tire. The adoption of reasonable tire assembly can be a good solution to the traffic demand and the contradiction between the characteristics of the tire.
