Explained in our guides
Read these before choosing wheels for the TT: 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.

Factory-diameter 18-inch

Listed by Caractere for the 8N, including the 3.2. Confirm the chosen spoke profile against the brakes; spacers change the effective offset.
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
- Later 8J TT wheels use 5x112 and are not a direct bolt-on replacement.
- The 3.2 has larger brakes; check a wheel-specific clearance drawing before choosing a smaller diameter.
- Use bolts with the correct seat and length for the wheel. Factory Audi bolt seats differ from many aftermarket designs.
- The quattro Sport special edition is not represented by a dedicated factory row here; verify its axle-specific wheel markings before ordering replacements.
- 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.
