Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2019 Audi S5. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 103 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Center-bore records disagree (donor year-level hub 66.6 mm vs trim range 66.5–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Approximate position vs the mid OEM package: outer change -2.85 mm, inner change -9.85 mm. This uses aggregated width/offset ranges, not a specific wheel.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.

2019 Audi S5 wheel fitment and interchange guide
tl;dr
Use the calculator on wheelinterchange.com to compare donor wheels to your 2019 S5. Keep bolt pattern 5x112 and a wheel center bore that seats to 66.5 mm. Match thread size M14 x 1.5 and the correct lug seat. Start from the OEM baseline 18x8.5 ET29 on 245/40R18, then change one variable at a time. Test fit for brake and fender clearance before committing.

Notes. Some trims and packages can vary. If your door-jamb sticker or OEM literature shows different values, use those in the calculator and proceed with that baseline.
Recommendation
I start by setting Installed on to 2019 Audi S5 in the calculator, then load Wheels from for your donor vehicle or enter a Custom wheel size. Enter one change at a time. If you change rim diameter, the calculator updates tire diameter for you. Keep overall tire diameter close to OEM to protect speedometer, gearing, and ABS behavior. Ensure donor wheels have a center bore equal to 66.5 mm or larger. If larger, plan hub-centric rings to 66.5 mm. Verify hardware: M14 x 1.5 threads and the correct seat style for the wheel. Finish with a physical test fit to check caliper and fender clearance at full lock and compression.
Impact
Offset changes move the wheel inboard or outboard. This affects strut, upright, and fender clearance. The calculator shows inner clearance change and outer poke.
Width changes alter inner and outer position even if offset stays the same. Wider rims also change tire sidewall shape and can expose rim lips.
Diameter changes reduce sidewall height if overall diameter is held constant. Ride comfort and impact harshness will change. Brake caliper face clearance may improve with larger diameters but barrel clearance still matters.
Tire size adjustments change section width and sidewall. The calculator highlights diameter delta and speedometer error so you can keep it close to stock.
Unsprung mass affects steering feel and braking. Heavier assemblies can lengthen stopping distances.
Risks
Rubbing. Inner interference at the strut, knuckle, or liner. Outer contact with fenders during compression or steering.
Hub fit. A wheel center bore smaller than 66.5 mm will not seat. Larger bores require quality hub-centric rings to 66.5 mm.
Lug interface. Incorrect seat type or thread size can loosen hardware or damage wheels. Hardware length must suit the wheel and any spacers.
Brake clearance. Spoke and barrel shapes vary. Offset alone does not guarantee caliper clearance. Always test fit.
TPMS. Sensor compatibility and programming can vary by sensor brand. Plan for relearn or programming when swapping wheels.
Next actions
Checklist. Confirm your exact OEM wheel and tire sizes from the door-jamb label or the owner’s manual.
Open the calculator. Set Installed on to 2019 Audi S5. Enter donor wheels or use Custom wheel size and Custom tire size.
Keep overall tire diameter close to OEM. Watch the calculator’s diameter and speedometer change readouts.
Verify fit basics. 5x112 bolt pattern. 66.5 mm hub seat. M14 x 1.5 threads. Correct lug seat for the wheel.
Plan hub-centric rings if the donor wheel bore is larger than 66.5 mm. Skip wheels with smaller bores.
Inspect brake clearance. Use a test fit to check spoke-to-caliper and barrel-to-caliper space through full rotation.
Cycle suspension. Check clearance at full lock, over a bump, and with load if possible.
Torque to the factory spec from the owner’s manual using a calibrated torque wrench. Re-check torque after initial miles.
Gotchas. Do not force-fit a smaller center bore. Do not mix seat types between hardware and wheels. Do not assume caliper clearance from diameter alone. Let the calculator guide your short list, then validate by test fitting.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
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.
