Product validation

Once the product and tooling have been validated, prototypes are validated on our test benches to correlate the results with the simulations.

COBAWHEELS™ technology

With this patented technology, Saint Jean Wheels is pushing back the technical boundaries of traditional wheel manufacturing processes by using better materials combined with the most advanced production techniques.



This proven technology for manufacturing lighter aluminum suspension parts has major advantages: significant design flexibility, improved mechanical properties and very good fatigue resistance.



This process, commonly used in the manufacture of cast aluminum rims, is applied by Saint Jean Wheels to an extruded tube to reduce the weight of the rim well.


Friction stir welding

This manufacturing process is used in the aeronautical sector and for certain specific automobile applications. Saint Jean Wheels uses it to weld the two parts of the rim, with no metal filler, no matter which alloys are used.
