The C7 RS6 Avant came on 9.5-inch wheels in 20 or 21 inches, which leaves room under the arches. Owners usually fit 10.5-inch wheels in 21 or 22 inches, often with a modest drop, and pick a spoke design that clears the large front brakes.

An RS246 owner runs this on H&R 20 mm lowering with no spacers and reports no rubbing, although the wheel sits closer to the suspension than stock. LFI's suggested 21-inch C7 spec is a similar 21x10.5 ET20 with 285/30 R21.
Shown in the Wheel Front gallery on Vossen HF-4T wheels. The 295 tyre is tight, so get a proper alignment and keep an eye on the arch liners. Another gallery car runs 22x10.5 ET35 with 15 mm front and 20 mm rear spacers.
One RS246 owner runs 15 mm spacers on top of ET20 (about ET5 effective), lowered on adjustable air-suspension links with steel brakes, and reports no rubbing. Another owner trying something similar had serious front rubbing, so treat this as the limit, not a safe default.
Width and offset guidance
Offset range
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.
Common width limit
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.
Clearance notes
Factory wheels use M14x1.5 ball-seat bolts. Aftermarket wheels with conical seats need different bolts, and spacers need longer ones.
The hub is 66.5 mm; some wheel makers quote 66.6 mm for the bore. Owners report that older C6 RS6 wheels needed adapting to fit, so check the bore before reusing them.
Torque is 120 Nm for the factory wheel bolts.
Audi's smallest factory RS6 wheel is 20 inches. Aftermarket 20s can clear the brakes, including ceramics, but need spokes that angle steeply away from the hub to clear the calipers.
Owners on air suspension often lower with adjustable links. The ride height and suspension mode you settle on change arch clearance, so test-fit at the final height.
Wider 22-inch setups need careful alignment. One owner on 22x11 wheels fitted front upper camber bushes to gain extra camber and arch clearance.
Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.

5x112 with a 66.5 mm centre bore. It uses M14x1.5 ball-seat bolts torqued to 120 Nm.
What size wheels came on the C7 RS6 Avant?+
20x9.5 ET21 with 275/35 R20 tyres, or 21x9.5 ET25 with 285/30 R21 tyres. Both are square.
Will 20-inch wheels fit over C7 RS6 ceramic brakes?+
Some do. Owners have fitted 20-inch BBS designs over ceramics, but the spokes must angle sharply away from the centre to clear the calipers. Check the exact wheel.
What tyre fits a 21x10.5 wheel on an RS6 C7?+
285/30 R21 is the usual choice. It matches the factory 21-inch tyre size and owners run it without rubbing when slightly lowered.
What size tyres does the Audi RS6 Avant C7 have?+
Factory tyre (tire) sizes for the 2013–2018 Audi RS6 Avant C7 are 275/35 R20 and 285/30 R21, depending on trim. Your tyre placard shows the size for your car.
What is the Audi RS6 Avant C7 centre bore?+
66.5 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
What is the Audi RS6 Avant C7 wheel bolt torque?+
120 Nm (about 89 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.
