The S3 8Y uses a square 8J wheel from the factory in 18 or 19 inches. Its standard brakes leave room for 17-inch wheels with the right design, so track owners often go smaller and lighter, while street cars usually move to a wider 18 or 19-inch wheel at a slightly lower offset.

Read these before choosing wheels for the S3: 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.
Apex's most popular S3 street fitment, a direct fit with no spacers or hub rings. 245/40 R18 or 245/35 R18 also fit; 255/35 R18 works on street tyres but not wide-shouldered track compounds.
The usual choice if you run an aftermarket big brake kit that needs 18 inches. Aggressive track tyres want extra front and rear negative camber; 265/35 R18 requires it.
Apex states its 17-inch designs clear the standard S3 8Y brakes. Extra negative camber is recommended with sticky tyres; 245/40 R17 is the easier street fit. Not suitable over most big brake kits.
Keeps the factory 19-inch look with an extra inch of width. 255/30 R19 also fits but needs added camber with track tyres.
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 S3. Try the wheels, colour and stance before you spend on parts.

18x8 ET46 with 225/40 R18 tyres, or 19x8 ET49 with 235/35 R19. Both are the same size front and rear.
Yes, with the right design. Apex lists a 17x9 ET42 wheel that clears the standard S3 brakes, usually run with 255/40 R17 or 245/40 R17 tyres.
140 Nm per Audi's table for later A3 types. Some guides list 120 Nm, so check the figure in your owner's handbook.
235/40 R18 is the common pick. 245/40 R18 and 245/35 R18 also fit without modification.
Factory wheels are 18 × 8 inch and 19 × 8 inch, depending on trim. The stock table lists the offset for each.
57.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
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.
