Rotating-bending test
An endurance test that simulates the lateral forces experienced in a curve.
Rolling test
Simulates the forces that act on the wheel when the vehicle is driving in a straight line.
Radial impact test
Primarily tests the strength of the wheel’s rim well.
Ridge test
Simulates driving over a curb, over potholes, etc.
Testing the material characteristics
A tensile strength test and a crystallographic image determine the energy absorption characteristics of the rim flange to ensure a high level of casting quality.
CASS test
A copper accelerated acetic acid spray solution tests the hardness and integrity of the paintwork.
Climate and condensation test
The wheel paintwork is exposed to extreme heat and high humidity.
X-ray and computer tomography tests
These tests detect any small inclusions or gas bubbles in the wheel.
