The RS Q8 uses square 22 or 23-inch wheels around very large ten-piston front brakes, so smaller wheels are not an option. Most owners keep 23 inches and 295/35 R23 tyres, using spacers or lower-offset forged wheels to push the wheels out to the arches, often on lowering links.

An RS Q8 owner on AudiWorld runs 12 mm front and 15 mm rear spacers on the factory wheels with no problems, giving about ET6 front and ET3 rear. Use longer ball-seat bolts to suit the spacers.
Owners use the factory 22-inch wheels with 275/40 R22 winter tyres. Some have raised concerns about rubbing with certain winter tyre models, so check clearance on full lock.
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. Most aftermarket wheels need different bolts, and spacers need longer ones.
Torque is 160 Nm, the figure Audi uses for the Q7 and Q8 family. This is higher than the 120 Nm used on RS4, RS5, RS6 and RS7 models.
Standard brakes have 420 mm front discs with ten-piston calipers. Optional ceramics, standard on the RS Q8 performance, have 440 mm front discs. Audi's smallest RS Q8 wheel is 22 inches, and owners report that 20-inch wheels will not clear the calipers.
Audi quotes 295/35 R23 as the factory tyre. Owners say 305 is about the widest tyre that suits a 10.5-inch rim; going wider means a wider wheel.
With spacers thicker than about 15 mm, owners suggest dropping to a 285 tyre to avoid rubbing.
Large changes in rolling diameter or tyre width can affect the driver assistance systems and may need declaring to your insurer.
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.

Can I fit 21-inch wheels on an RS Q8?+

On the factory 10.5-inch rim, about 305 wide. Builds with 325/30 R23 tyres use 12-inch wide wheels.
