Audi RS6 Avant C8 wheel fitment
The C8 RS6 uses wide square wheel packages rather than wider rear wheels. Owners commonly choose 21s for more sidewall or lower-offset 22s, with brake and dust-shield clearance checked for the specific wheel.
5x112 bolt pattern · 66.5 mm centre bore · Stock wheels: 21 × 10.5, 22 × 10.5 inch · Stock tyres: 275/35 R21, 285/30 R22

Explained in our guides
Read these before choosing wheels for the RS6 Avant: they explain the offset, fitment and hub numbers in this guide.
- Wheel offset explained: choosing ET without guessingUnderstand positive and negative wheel offset, calculate inner clearance and outer position, and choose an ET using measurements from your own car.
- Flush, poke and tucked fitment: measure the whole tyreUnderstand flush, poked and tucked wheels, calculate how width and offset change the look, and check clearance beyond a parked side-on photograph.
- Hub-centric vs lug-centric wheels: choosing hub ringsLearn what hub rings do, how to specify their inner and outer diameters, and why centring, wheel seats and vibration need separate checks.

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 ball-seat bolts. Match the bolt seat and length to the replacement wheel; a matching thread alone is not sufficient.
- The nominal hub is 66.5 mm; some wheel suppliers describe the corresponding bore as 66.6 mm. Obtain the wheel manufacturer's C8 RS6 application confirmation.
- A wheel that fits a C7 RS6 or RS7 is not automatically clear of the C8 brake dust shields.
- Check the exact brake package, wheel load rating and tyre load rating. Diameter and width alone are insufficient for this car.
- The standard 21 and 22-inch packages use the same tyre sizes front and rear. The different offsets in the Vossen example do not call for different tyre sizes.
- 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.
