2015–2021 · saloon and coupé
The W205 C63 is a staggered, rear-drive V8 car, and the saloon and coupé use very different wheels because the coupé has wider rear arches and a wider front track. Owners mostly chase a flush 19 or 20-inch staggered set with a slightly wider front tyre, keeping offsets close to factory.

Read these before choosing wheels for the C63 / C63 S: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Reported on MBWorld by a saloon owner as fitting flush with no rubbing. The front sits only slightly further out than the factory ET38 wheel; the rear face stays close to stock.
Chosen by an MBWorld C63 S coupé owner alongside KW height-adjustable springs, and listed by FMB Wheels as the most documented coupé setup. Coupé only; the saloon has narrower rear arches. Watch the front arch liner if lowered.
A bagged C63 S saloon on MBWorld runs 15 mm front spacers (effective ET25). The owner reports the rear tyre almost touching the arch when aired out, so this only suits air suspension or careful ride-height setting.
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Upload a photo and start with a look that suits the C63 / C63 S. Try the wheels, colour and stance before you spend on parts.

These tools start with the C63 saloon, 18-inch front size. Choose your own trim or axle in the calculator if it differs.
5x112 with a 66.6 mm centre bore. It uses M14x1.5 wheel bolts with a ball seat, torqued to 130 Nm per the Mercedes handbook.
They bolt on, but the coupé uses wider, lower-offset wheels (9J ET25 front, 10.5J ET57 rear) for its wider body. On a saloon the fronts stick out a long way, so they are not a sensible swap.
With the 19/20-inch package it runs 255/35 R19 front and 285/30 R20 rear. The all-19-inch coupé package uses 285/30 R19 at the rear.
Yes. A commonly reported flush set is 20x9.5 ET35 front and 20x10.5 ET57 rear with 265/30 R20 and 285/30 R20 tyres, without rubbing at standard height.
Factory wheels are 18 × 8.5 inch, 18 × 9.5 inch, 19 × 8.5 inch, 19 × 9.5 inch, 19 × 9 inch, 19 × 10.5 inch and 20 × 10.5 inch, depending on trim. The stock table lists the offset for each.
66.6 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
130 Nm (about 96 lb-ft) for the original bolts. Confirm in your handbook, especially with aftermarket wheels or bolts.
This guide is a starting point, not a fitment guarantee. Specs can differ by market, trim and previous modifications. Confirm all sizes, clearances and fastener requirements with a qualified wheel and tyre professional before buying or fitting parts.
