Wheel 10,5 x 22" Type AC5 for BMW

Philosophy/Design

The circumferential undercut reflects the high technical standard of the AC5 Flowforming rim. This is because this design element can actually only be realised if it is machined out of a solid material, such as is required in the forging process, as it is located behind the spokes. The undercut of the AC5 Flowforming rims is particularly visible on the BiColor version, as it brings out the high-quality aluminium with its silver surface.

Material

Only high-quality aluminium alloys are used. The material is additionally heat-treated in the production process, which results in higher strength and simultaneous weight reduction.

Material samples during the production process guarantee the constant and high quality of the material.

Manufacture

The flowforming process is one of the most advanced manufacturing technologies in wheel industry. In this production process, after the actual aluminium casting, the raw product is further processed by rolling it out. This step serves to compress the metal, which guarantees greater stability and impact resistance of the rim.

On the other hand, the improved stability also allows the design of the wheels to be more filigree, as the wall thicknesses can be significantly thinner compared to conventionally manufactured rims.

Test Procedures / Safety

After their design, the first sample rims are manufactured under real production conditions. These must undergo a multitude of tests. Among other things, the strength is tested. The "rim life" is simulated in the bending circumferential test. Every AC Schnitzer rim must withstand this intact in order to be allowed to be produced and sold at all.

This is followed by vehicle-specific tests, including test installations with check of unobstructed movement and driving tests on public roads and on race tracks. Only after these procedures our rims receive their homologation, i.e. the approval to be used in road traffic.

Wheels are safety-relevant components. Therefore, they are checked and tested with the greatest care. This starts with the first chemical material tests and ends with hard testing machine endurance runs:

• § 30 StVZO wheel guideline
• ECE R124
• Bending-rotation tests
• 90° impact test
• unwinding tests
