GB/T 29041-2023 specifies the test method for road wear performance of automobile tires, applicable to the comparative wear testing of new pneumatic tires for passenger cars, micro/light trucks, trucks, and their retreaded tires. The standard defines the requirements for test equipment, procedures, records, and tire rotation rules. It evaluates the wear performance of tires by measuring the change in tread depth after a specified mileage of driving. The test requires instruments such as speed sensors, thermometers, pressure gauges, wheel load meters, tread depth gauges, dynamic balancing machines, and GPS positioning systems to precisely control parameters such as driving speed, tire pressure, and load. This provides a unified technical basis for tire quality control and performance comparison.
