GB/T 45144-2024 in English

The Standard GB/T 45144-2024 "Road Vehicles - General Requirements and Conditions for Scrapping of Wheels and Rim" is a comprehensive guide designed to ensure the safe use, maintenance, and disposal of wheels and rims in road vehicles. This standard provides detailed specifications for wheel and rim dimensions, material selection, manufacturing processes, inspection criteria, and quality control measures essential for vehicle safety and performance.

Effective from July 1st, 2025, this regulation outlines critical aspects such as load capacity ratings, maximum speed limitations, fatigue testing procedures, corrosion resistance standards, and wear indicators. It emphasizes the importance of regular inspections to identify signs of deterioration or damage that may compromise vehicle safety. Additionally, it includes criteria for determining when wheels and rims should be scrapped based on usage life cycles, accident history, environmental exposure factors, and structural integrity assessments.

The document aims at enhancing road safety by setting stringent requirements for the durability and reliability of wheel and rim components across various types of vehicles including passenger cars, commercial trucks, buses, motorcycles, and specialty vehicles. By adhering to these guidelines, manufacturers, suppliers, maintenance providers, and end-users can contribute significantly towards reducing accidents caused by faulty or improperly maintained wheels.

Moreover, it encourages the development of advanced materials science research and technological innovations aimed at producing more robust yet lightweight wheel and rim designs without compromising on safety standards. This initiative supports the continuous improvement in automotive industry practices to meet modern transportation needs while ensuring public welfare.
