Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2016 Audi S5. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 188 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)
Center-bore records disagree (target year-level hub 66.6 mm vs trim range 66.5–66.5 mm; 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. Approximate position vs the mid OEM package: outer change -1.17 mm, inner change -5.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionWheel spacer ≈ 11.18 mm – not a verified installation requirement.
A spacer of about 11.18 mm is a dataset suggestion only; clearance is not verified. Estimated outer position is about 11.18 mm farther inward than the mid OEM package.

2016 Audi S5 wheel fitment guide
tl;dr
Your 2016 Audi S5 uses 5x112 bolt pattern, 66.6 mm center bore, and M14 x 1.5 wheel bolts. A known OEM wheel example is 20 x 9.0 with ET 29 and about 5.64 in backspacing. A separate OEM tire example listed here is 245/40R18. Those represent different OEM packages. Do not mix an 18 inch tire on a 20 inch wheel. Use the on-page calculator to compare any donor wheel or custom size to your car, then confirm against OEM sources before buying.
Recommendation
I treat this in four steps: identify, compare, select, install.
Identify: Confirm your current package. Read the wheel stamp for size and ET. Read your tire sidewall for size. Cross-check the door jamb or Audi service data.
Compare: Use the calculator on this page. Set “Installed on” to 2016 Audi S5. Enter your current wheel and tire. Enter the donor or custom sizes. Review inner clearance, outer poke, and tire diameter change.
Select: Keep hub-centric fit at 66.6 mm. Keep M14 x 1.5 hardware. Match the lug seat type to the wheel manufacturer. Only choose offsets and widths that clear suspension, brakes, and fenders with your ride height.
Install: Test-fit a front and rear corner. Spin the wheel by hand. Check lock-to-lock and full compression clearance. Torque to the Audi spec from the owner’s manual or service manual.

Important: The 20 x 9.0 ET 29 wheel and the 245/40R18 tire belong to different OEM setups. Match wheel and tire diameters when planning a set.
Impact
Width change: Wider wheels can reduce inner clearance and increase fender poke. The calculator shows both directions.
Offset change: Smaller ET pushes the wheel outward. Larger ET pulls it inward. Watch for strut, liner, and fender contact.
Tire diameter change: A larger tire raises ride height, alters speedometer, and can affect ABS and gearing. Keep the variance small per your risk tolerance.
Center bore and hardware: Non-66.6 mm aftermarket wheels need hub-centric rings to 66.6 mm. Use correct-seat M14 x 1.5 bolts.
Brake clearance: Face design matters. Spoke profile can hit calipers even if math clears. Always test-fit.
Risks and gotchas
Mixing package data: Do not pair 18 inch tires with 20 inch wheels. Keep matched sets.
Rubbing under load: Clearance at static height is not enough. Check bump and steering lock.
Vibration: Running lug-centric without proper hub rings on a 66.6 mm hub can cause vibration.
Bolt seat mismatch: Ball vs conical seats must match the wheel. Mismatch can loosen under load.
Thread engagement: Using spacers needs longer M14 x 1.5 bolts. Ensure safe thread engagement depth per OEM practice.
Load rating: Wheels and tires must meet or exceed vehicle axle loads.
TPMS compatibility: Reuse or program sensors as required for your S5.
Torque: Follow Audi torque spec from the manual. Do not guess.
Next actions
Document your current wheel stamp (size and ET) and tire sidewall.
Open the calculator. Set your current setup under “Installed on”.
Enter the donor or custom wheel and tire under “Wheels from” or “Custom”.
Review inner clearance, outer poke, and tire diameter change. Aim for no interference.
Confirm hub bore is 66.6 mm or plan hub-centric rings to 66.6 mm.
Match M14 x 1.5 hardware and correct lug seat. Plan bolt length if using spacers.
Cross-check against an OEM source or trusted fitment data before purchase.
Test-fit, torque to spec, road test, then re-torque after 50–100 miles.
Hub bore: Your S5 hub is 66.6 mm. Rings adapt larger aftermarket bores down to 66.6 mm.
Hardware: Thread is M14 x 1.5. Seat type and bolt length depend on the wheel and any spacer.
Final check: If any value is unknown or differs by trim, verify with the on-page calculator results and Audi factory documentation.
You can complete a safe, clean fitment by following the checklist and letting the calculator do the geometry. If a spec is missing, pause and confirm. That saves time, money, and avoids avoidable rubbing or vibration.
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.
