1980 Start of production of light alloy wheels.


4000 employees take care of the development, production and distribution of CMS wheels for the OE or aftermarket every day.


10 million alloy wheels are produced per year for the European automotive industry and aftermarket.


40 years of CMS experience in safety, quality and enjoyment of the car.

CMS Technology & Competence


By state-of-the-art production facilities, up to date with the requirements demanded by German premium manufacturers guidelines, decades of know how and high flexibility, CMS has been able to take a top position in the European market for alloy wheels. Everything from one source - from toolmaking to shipping the wheels, in close cooperation with the automotive industry, our wheels meet the highest quality standards. Our plants are producing according to ISO 27001, ISO 16949, ISO / TS 9001, ISO 18001 and ISO 10002

CMS Technology & Competence


An ABE certificate is available for all CMS wheels. Due to standart offset and wheel sizes close to the OEM series production, the registration requirement dispenses for most applications. Due to European guidelines of the Economic Commission for Europe ECE R124, the European wheel market demands more and more for wheels with ECE standard. ECE wheels are „reversed engineered wheels“ which are based in the technical dimensions of the original wheels which are already registered in the vehicle documents. The wheels are marked with the ECE symbol and the ECE approval number. No documents need to be carried.

CMS Technology & Competence


The wheels for the aftermarket are specially designed and developed by CMS itself. Modern highly professional software is used to reconcile design requirements with technical demands. A motivated dedicated team combines trendy ideas with the high standards of OEM quality. Through the close cooperation with the automobile manufacturers CMS always meet the spirit of the times and marks trends.


CMS – Sustainability

"We need to set high goals even though they may seem impossible, but it is our obligation to our children and future generations. Legal requirements are not enough to achieve this." (Sustainability Coordinator CMS)

Under the guiding principle "Wheels into Future", we have been strategically committed to sustainability for over 10 years.

Despite our growth strategy, the environment and social components have been among our central issues from the very beginning.
We see it as our responsibility to lead the way with a sustainable growth model. We define clear quantifiable goals and involve all stakeholders in the value chain.

We are proud to have already achieved a lot:
- Saving raw materials
- Reduction of environmental impacts, especially energy consumption and greenhouse gas emissions
- Reduction of water consumption, e.g. through waste water management
- Reduction and recycling of waste, especially aluminium waste and aluminium chips
- Creating a healthier working environment for employees

Simply by choosing suppliers that use renewable energy sources, the carbon footprint can be reduced by 40%. We have a 5-year plan to reduce CO2 emissions by 15% compared to 2020.

Currently, the CMS Group is investing approximately 25 million euros in a solar park to produce the entire electricity needs of the four plants with solar energy.

CMS Technology & Competence

Die casting

All our wheels are manufactured using low pressure casting. In this process, the aluminium alloy is pressed into a mulit-part mold at a pressure of 1.2 bar. This guarantees an even distribution of th aluminium in the casting mold. This in turn ensures a uniform quality in terms of material density and radial run-out.

CMS Technology & Competence

X-ray inspection / leakeage control

100% of the cast wheels are x-rayed. By x-raying the wheels any air entrapment as well as various surface defects are detected and the affected wheels sorted out. This important quality criterion guarantees our customers the highest level of driving safety. 100% of the wheels are fully automatically tested for leaks by a helium gas testing system before painting. This guarantees double safety in terms of air loss.

CMS Technology & Competence

Flow - forming

Flow-forming has been developed as an additional process to reduce wheel weight compared to conventional cast wheels. By rolling out a cast blank under high pressure, a significant densification and consolidation of the material in the rim is achieved, which leads to a significant saving in material.

CMS Technology & Competence

Heat treatment

The additional heat treatment of the wheels compacts the aluminum and enlarges its strength and load capacity. The densification of the material allows significant material saving, which in turn reduces the weiht of the wheels.

CMS Technology & Competence


Our wheels are varnished with both technically and environmentally state-of-the-art painting equipment in accordance with the guidelines of German premium car manufacturers. In addition, environmentally friendly lacquers are used in accordance with EU regulations. A100% visual inspection guarantees perfect surface quality."
