2020 Audi A3 wheel fitment tl;dr
Keep 5x112, 57.1 mm center bore, and M14x1.5 hardware. Use the on-page calculator before you buy. Confirm your trim’s OEM wheel and tire sizes from the door jamb and owner’s manual. Stay hub-centric and avoid large offset changes without measurements.

Tire size example
225/45R17
Note: The listed 16 inch wheel and 225/45R17 tire indicate multiple OEM setups exist by trim or package. Verify your exact OEM size from the tire placard and OEM sources, then use the calculator for like-for-like comparisons.
Recommendation
Start from your actual OEM baseline
Read the tire placard on the driver door jamb and the wheel stamps. Record wheel diameter, width, and ET, plus current tire size. Use these as your “Installed on (your vehicle)” baseline in the calculator.
Match the critical interfaces
Bolt pattern must be 5x112.
Center bore should seat on 57.1 mm. If the new wheel bore is larger, plan hub-centric rings to 57.1 mm.
Thread is M14x1.5. The A3 typically uses lug bolts, not studs. Confirm seat type on your current bolts before reusing.
Change size methodically
Adjust custom wheel width and offset in small steps in the calculator.
Watch inner clearance to the strut and liner. Do not reduce clearance to a rub risk.
Watch outer “poke” relative to the fender edge. Keep it inside the arch for street use.
If changing rim diameter, set the new tire size so overall diameter stays near OEM. The calculator updates tire diameter as you change rim diameter.
Confirm with measurements
Measure current clearances at full lock and over bumps if possible.
Check brake caliper spoke clearance with a template or a test fit.
Impact
Offset changes move the wheel inboard or outward, altering scrub and bearing load.
More width can improve grip but tightens inner and outer clearances.
Overall tire diameter shifts speedometer and gearing feel. Keep it close to stock for daily use.
Larger diameter wheels often add weight and reduce ride compliance.
Hub-centric fit reduces vibration at highway speed.
Risks and gotchas
Mismatched center bore causes vibration without proper rings.
Wrong seat type on lug bolts can loosen under load. Verify ball vs cone seat visually or by part number.
Insufficient thread engagement is unsafe. Ensure full, clean engagement of M14x1.5 bolts. Replace stretched or corroded hardware.
Caliper or barrel contact can occur on some spoke designs even if diameter “fits.” Always test fit.
Large offset swings can cause inner liner rub or poke past the fender.
TPMS and tire load ratings must match your market and trim requirements.
Torque spec varies by model and market. Use the owner’s manual or OEM documentation for the correct value.

Checklist
Confirm your OEM baseline from the door placard and wheel stamps.
Open the calculator on wheelinterchange.com and set your current wheel and tire sizes under “Installed on (your vehicle).”
Enter your candidate wheel under “Wheels from (donor vehicle)” or use “Custom wheel size.”
Adjust rim diameter and width. Set a matching tire size so overall diameter remains near OEM.
Review inner clearance, poke, and tire diameter change. Revise offset as needed to keep safe clearances.
Plan hub-centric rings to 57.1 mm if the new wheel bore is larger.
Verify lug bolt seat type and length, and torque to OEM spec.
Test fit one corner, spin by hand, check lock-to-lock, then road test carefully.
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
