GB/T 22391-2017 "Solid tire durability test method, rotary drum method" standard specifies the terms, definitions, test equipment and its accuracy, test conditions, steps and reports of the durability test of solid tires. The standard applies to new solid tires. Durability test is carried out by rotary drum method to evaluate its performance in long-term use. The test involves the use of rotary drum equipment to simulate the operation of tires under actual road conditions, so as to test their durability. The implementation of the standard helps to ensure the stable performance and safety of solid tires. It is suitable for tire durability evaluation in various application scenarios.
