Audi S3 8V wheel fitment
The S3 8V commonly uses square 18-inch aftermarket wheels for road and track driving. Factory 18-inch dimensions differ between the hatchback and saloon, so the body style matters when copying an original wheel package.

Explained in our guides
Read these before choosing wheels for the S3: 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.
- A larger aftermarket centre bore needs correctly sized hub rings; a smaller bore will not seat on the hub.
- The 18-inch hatchback wheel is 7.5J ET51, while the saloon and cabriolet package is 8J ET46. Check body style and part number.
- Use 120 Nm. Audi's October 2023 workshop table specifies 120 Nm for type 8V; an older general Audi table groups later A3 models under 140 Nm. The newer type-specific manufacturer entry takes precedence here.
- Brake clearance depends on the wheel design. Apex lists selected 17-inch wheels, but that does not establish clearance for all 17s.
- 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.
