This document describes the laboratory test methods for performance testing of truck tires, including test instruments and equipment and their accuracy, test conditions, test procedures, determination rules, and test reports. Among the proposed test methods, only the application of certain test methods is determined by the type of tire being tested. This document includes: -- Durability performance test: Evaluating the tire's fatigue resistance by measuring the driving time under specified loads and speeds; -- High-speed performance test: Evaluating the tire's high-speed driving performance according to the tire speed symbol; -- Strength performance test: Evaluating the tire's structural performance by detecting the damage energy of the tire crown. The test methods listed in this document are not suitable for grading the performance or quality level of tire products. This document applies to new pneumatic truck tires and refurbished pneumatic truck tires. For other tires, with the consent of relevant parties, the test methods in this document can be referenced for testing.
