As fuel costs and tire costs continue to increase, the operating costs of logistics companies continue to grow, and users are very concerned about the use of tires. They want to choose high-cost tires and reduce replacement. Because there is no suitable tool to measure, and there is no authority to publish relevant comparative data, the choice of tires is based more on traditional experience. In view of this, the first "Commercial Vehicle Tire King" evaluation activity sponsored by "China Automotive News" and Haiyi Sanying Commercial Vehicle Positioning Equipment Co., Ltd. was launched at Beijing China Railway Logistics Group. 10mm aluminium tube,aluminium round tube sizes,aluminium round pipe,round tube aluminium Guangdong Huachang Group Co., Ltd. , https://www.gdhcaluminum.com
The event was positively responded to by the manufacturers of commercial vehicle tires and logistics and passenger transport companies. Bridgestone, Giti, Linglong, Haida and other tire companies enthusiastically applied for registration. After review by the organizing committee, seven tires were selected for testing from China. China Railway Logistics Corporation selected four trucks, including JAC, to be used for evaluation in more than 1,000 logistics vehicles owned by the company. Beijing Wanhao Car Rental Co., Ltd. provided 3 Zhongtong Kaigao buses for evaluation.
The main test content includes four major categories, namely, fuel consumption, wear, repair rate, and tracking visits to drivers. The fuel consumption test method is to count the fuel consumption every 500 kilometers, and to calculate the total fuel consumption and the average fuel consumption of 5,000 kilometers when it reaches 5000 kilometers. The degree of wear test was: Before the test, the depth of the tread was accurately measured with a vernier caliper and photographed; after the test began, the depth of the tread was measured once every 1000 km and photographed; after 5,000 km, the data was compared and compared before use. Degree of wear. The content of the repair rate test is: the number of tires worn or repaired by each brand within 5,000 kilometers will be counted. Photographs will be made on the tyres that have undergone repair. If the tyres are found to have quality problems, they will be sent to the national testing agency for special quality inspection. Tracking the driver's visit is mainly to subject the driver to subjective evaluation of the tire's high-speed, grip, handling, and comfort.
In order to make the test results more accurate, each type of vehicle is equipped with different brands of tires, and tracking tests are carried out according to the actual operations of the logistics and passenger transportation companies. The test time is one month, and the test distance is guaranteed to be more than 5,000 kilometers. One month after the tracking test, the data of each tire's wear, repair rate and other data were collected and evaluated.

Old tire retreading and new tire identification method
Distinguish the point one: Observe the pattern color and luster of the tire From the grainy road, under normal circumstances, because the inferior retreaded tire processing is not standardized, the groove is relatively shallow. In terms of color, poor retreaded tires look bright and shiny, while the regular retreads are relatively dark. The refurbished tires are bleak in color and luster.
Identify the second point: Observe the overlapping parts of the tread and the sidewalls. Firstly, look at the side of the tires and check whether the various labels are complete. Each tire manufacturer has a forum pattern code to see if the pattern code corresponds to the tire pattern. Next, look at whether the joint between the tread and the carcass of the tire shoulder is smooth, and the retreaded tires are self-made treads that are attached to the old carcass. The lap joint between the tread and the sidewall is not as good as the new tire. There are binding marks on the sides.
Discerning Point 3: Tire marks, brand tires produced by regular manufacturers, have some prominent marks on the tires, indicating the type and performance of the tires, the date printed on the inner side and the wear marks in the skid-proof grooves on the treads are clearly visible. The signs for retreaded tires are mostly re-posted. Using nails to scratch these marks, it must be retreaded tires.
