Purpose and rear axle fitment

The presented rim is designed for mounting on the vehicle's rear axle, which is crucial for proper load distribution and maintaining stability at higher speeds. The aluminum construction ensures a favorable strength-to-weight ratio, while the appropriately selected width and diameter of the rim allow for the use of tires with parameters typical for the premium segment. As a result, the rim fits well with the suspension characteristics of the Mercedes W212, supporting ride comfort and steering precision.

Structural characteristics of the rim

The rim belongs to the Wheels category and is made of a lightweight aluminum alloy, which helps reduce unsprung mass and improves suspension response to road irregularities. The applied diameter and width of the rim allow for the installation of tires with a sporty-comfortable profile, and the selected offset supports proper wheel seating in the wheel arch, minimizing the risk of rubbing against suspension or body components. The bolt pattern and number of mounting holes are consistent with the typical Mercedes hub architecture, facilitating trouble-free installation on the vehicle.

Exterior appearance and color scheme

The silver finish of the rim gives the vehicle a subdued, elegant character that blends well with both classic and more dynamic body lines. This color is practical for daily use – it optically masks minor dirt and typical signs of wear, while remaining consistent with the factory styling of most Mercedes W212 trim levels. The aluminum construction with a silver finish helps maintain visual consistency with other car elements, such as trim strips or chrome details.

Mounting parameters and user benefits

The rim offers a set of mounting parameters matched to Mercedes standards, including rim diameter, width, offset, center bore, and the number of mounting points. This configuration facilitates installation at a specialized service center or tire shop without the need for non-standard adapters. Precise fitment to the hub and running gear translates into reduced vibrations, improved ride comfort, and even tire wear, which is important for both safety and operating economy.

Condition, application, and safety

The rim is a used product, making it an attractive cost-effective alternative to new components while maintaining factory geometry and performance characteristics. It is a good solution for replacing a single rim after mechanical damage or when gradually rebuilding a set of wheels for the car. Using an original aluminum rim helps maintain predictable vehicle behavior in line with the manufacturer's design, which has a direct impact on driving safety, especially at higher speeds and during emergency maneuvers.
