With the ever-rising car ownership, traffic safety issues have attracted many concerns. In addition to the quality of the entire vehicle, the quality and configuration of parts such as engines, transmissions, tires, etc. have gradually become the focus of consumer attention. While consumers urged manufacturers to strengthen quality management, the national quality inspection department has also actively taken various measures to strengthen the supervision of the automobile and its accessories industry. Tire is one of the most important components of a car. Its quality is directly related to the safety of life and property of consumers.

Recently, Kumho Tire Co., Ltd., a well-known tire manufacturer, has submitted its KH18, 769 series products to the National Tire Quality Inspection Center. According to the national test standards, all Kumho Tire products passed the inspection. This is the second time that Kumho Tire has received the national quality inspection report after it came to China. As an integrated company with ISO/TS 16949 quality as its management system, Kumho Tire strives to create products that satisfy consumers, with quality as the core, and does its utmost to improve everything from design to manufacturing, testing, and logistics. Quality Management System. The qualified inspection report of the national quality inspection center is the recognition and recognition of the quality innovation of Kumho Tire.

The quality test was conducted in accordance with the GB9743-2007 standard. In addition to routine external inspections such as outer edge size, outer diameter, section width, and tread wear mark height, high-speed durability testers and tire section analysis machines were also used. International tire testing professional equipment, tire strength performance, high-speed performance, durability, off the circle resistance test.

From the test data point of view, Kumho Tire KH18, 769 two products have a good performance in the strict test conditions.

Taking the KH18 sampling specification 205/65R15 94H as an example, the national standard has an outer diameter of 639-655mm, a section width of 201-216mm, a tread wear mark height of ≥1.6mm, a strength performance of ≥295J, and high-speed performance of ≥210km/h. Durability ≥ 34h, knock-out resistance ≥ 11120N. The inspection data showed that the outer diameter of the KH18 sample was 645mm, the width of the section was 206mm, the height of the tread wear mark was 1.8mm, and the strength performance was 295J-464J. The high-speed performance, durability, and the knock-out resistance all met the standards.

It is reported that the National Tire Inspection Center, which is the National Tire and Rubber Products Quality Supervision and Inspection Center, was approved by the State General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) at the end of 2005 to establish a state-authorized wheel quality supervision and inspection agency in Qingdao. Test experts stated that the test items were all aimed at the quality of the tires and their functions, and were established in accordance with national regulations and international inspection standards. The outer diameter and outer diameter of the tire relate to the matching between the tire and the vehicle and the interchange between the tire and the tire. Section width and tread wear marks are related to the daily use, maintenance and replacement of tires. They are also an appearance indicator for testing the safety performance of tires. At the same time, the durability of the tire marks its durability, high-speed performance indicates the speed limit of the tire, and all performance standards are an important part of the tire quality.

In addition, the person in charge of Kumho Tire's China Quality Department stated that the test data is the quality standard of the tires. In fact, each tire is clearly marked with detailed tire information. This information has an intuitive reference meaning for consumers. Taking the tire size 205/65R15 94H as an example, from the standpoint of the factory, 205 indicates the tread width (mm) of the tire, 65 indicates the flattening rate (tire height/tire width), and R indicates that the tire belongs to the meridian structure, 15 It is expressed as the diameter of the rim (inches), 94 is the load index (indicating the maximum load is 670kg), and H is the speed code (indicating that the maximum safety speed is 210km/h). Consumers learn to read this information so that they can purchase, use, and care for their tires.
