Summary
This standard specifies test methods for laboratory performance testing of car tires, including testing terms and definitions, test procedures, , test conditions, test equipment and precision criteria and test reports. In the proposed test method, the test method only requires the application of certain types of decisions based on the measured tire (with tube or tubeless, bias tires or radial tires, etc.). The criteria include: (1) unseating resistance test-to assess the resistance value of the tubeless tire bead from the rim. (2) Strength test-can evaluate the performance of the tire structure by detecting the tire tread damage. (3) high-speed performance test-in accordance with the tire speed symbol, the evaluation of the tire at high speed performance. (4) Durability Test-required by load and speed in the driving time, the evaluation of the tire.
