Mercedes-Benz R-Class Wheels and Rims

Mercedes-Benz R-Class Aftermarket Wheel Fitment

The Mercedes-Benz R-Class is the W251 six passenger sports tourer Mercedes built and sold in the US from 2006 through 2012. The R-Class was Mercedes-Benz's attempt at a luxury family hauler with a long wheelbase, three rows of seating, and the driving feel of a higher riding sedan. Mercedes discontinued US sales after the 2012 model year. Production continued for export markets through 2017, but no US sales after 2012. Element Wheels measures fitment on the W251 R-Class as a single catalog platform. The bolt pattern is 5x112 with a 66.56mm hub bore. The lug fastener is M14x1.5, lug bolt style (Mercedes uses a bolt that threads into the hub, not a stud with a separate lug nut). The R-Class is a non-staggered square fitment platform in our catalog, meaning the front and rear wheels must run the same width and the same offset window. This is a hard rule on the R-Class, unlike most Mercedes coupes and roadsters where optional staggered is supported. The R-Class also carries the widest aftermarket diameter range on any Mercedes 5x112 platform in our catalog, running from 18 inch up to 22 inch. The brake package is same size front and rear, with an 18 inch brake caliper height. The AMG R 63 variant was European spec only and is not part of the US R-Class catalog.

Find Your Mercedes-Benz R-Class

The R-Class is a single chassis platform in our catalog (W251, 2006-2012 US). Bolt pattern is 5x112 / 66.56mm CB, square fitment, aftermarket diameter range 18-22 inch.

The Mercedes-Benz R-Class Bolt Pattern

Every Mercedes-Benz R-Class in our catalog uses 5x112 with a 66.56mm hub bore. That covers the W251 across the 2006 through 2012 US model years. Lug fastener is M14x1.5 thread, lug bolt style.

The 5x112 / 66.56mm pattern is the universal modern Mercedes-Benz spec, shared with the C-Class, E-Class, S-Class, GLC, GLE, and GLS. A wheel built for a contemporary GL-Class or GLE-Class will generally bolt onto an R-Class hub in stud pattern and centering. The R-Class is a long wheelbase sports tourer with its own fender lines, ride height, and tire clearance, so the body geometry differs from the SUV platforms. We track the R-Class as its own platform with its own measured fitment data, including the square fitment constraint.

5x112 is NOT the same as 5x114.3 used on most Japanese cars. The two patterns sit roughly 2mm apart and are not interchangeable. Compare across the rest of the Mercedes-Benz lineup at our Mercedes-Benz wheels and rims hub.

Why The R-Class Is A Square Fitment Platform

The R-Class is a non-staggered square fitment platform, meaning the front and rear wheels must run the same width and the same offset window. This is the major fitment topic on the R-Class. Most Mercedes coupes and roadsters support optional staggered layouts, but the R-Class does not. The chassis was engineered as a long wheelbase six passenger family vehicle, not a performance car, and the suspension and bodywork accommodate a single width per corner. The R-Class brake package is also same size front and rear with an 18 inch brake caliper height, which keeps the diameter floor at 18 inch. The aftermarket diameter ceiling runs all the way up to 22 inch, giving the R-Class the widest diameter range on any Mercedes 5x112 platform in our catalog. The R-Class also carries a wide aftermarket width window (8 inch through 10.5 inch) for both front and rear, but the front and rear values must match in any given setup.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.

How We Confirm Fitment on Mercedes-Benz R-Class Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the W251 R-Class. For the R-Class that means clearance from the wheel to the fender on a long wheelbase six passenger sports tourer body, gap between the back of the wheel and the front suspension components, brake caliper height across the standard 18 inch R-Class brake package, hub bore confirmation on the 66.56mm Mercedes hub, lug bolt seat depth for the M14x1.5 lug bolt, and verification that the front and rear width and offset values are matched on a square fitment chassis. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do.
