1.Material selection: The material of the wheel rim will directly affect the strength of the wheel rim.Common materials are aluminum alloy, titanium alloy, carbon fiber, etc.

2.Design structure: The structural design of the rim will affect the strength of the rim, such as the wall thickness and bending radius of the rim.

3.Manufacturing process: Different manufacturing processes will lead to differences in the strength of the wheels. For example, factors such as temperature and pressure need to be considered when casting wheels, while material deformation and holes need to be considered when forging wheels.

4.Use environment: The road conditions and load of the car when driving will affect the wheel rim, which will also affect the strength of the wheel rim. For example, heavy-duty trucks need stronger wheels.

5.External force: When the vehicle is driving, the wheel rim may be affected by external forces such as impact, which will also affect the strength of the wheel rim.
