OEM wheel and tire fitment specs for the 2012 Audi S4, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
Recorded OEM specifications for the 2012 Audi S4, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Center-bore records disagree: year-level hub 66.6 mm vs trim range 66.5–66.5 mm. Interchange below does not treat this as an unqualified match.

Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2012 Audi S4. 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 57.1–66.5 mm). Unqualified overlap is not claimed until the conflict is resolved. Approximate position vs the mid OEM package: outer change -0.17 mm, inner change -6.18 mm. This uses aggregated width/offset ranges, not a specific wheel.
Dataset suggestionHub-centric rings ≈ 66.6 → 66.5 mm – not a verified installation requirement.
Hub-centric rings of about 66.6 → 66.5 mm mm may be relevant if the wheel bore is larger than the hub; clearance is not verified. Donor width/offset sits outside the known OEM envelope for this vehicle.

Center-bore records disagree (target 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.

2012 Audi S4 Wheel Fitment Guide
You want a straight answer without sales fluff. I get it. Let’s set a safe baseline, walk the edge cases, then use the on-page calculator to validate every change before you buy hardware. If something is unknown or varies by trim, I will say so and show how to check.
1. Baseline
These are the known OEM specs for the 2012 Audi S4. Treat them as your reference point when comparing donor wheels or custom sizes.

If your trim or brake package is different, some clearances may vary. Set “Installed on” to 2012 Audi S4 in the calculator, then compare any donor wheel to this baseline. The tool will show poke, inner clearance, and diameter changes.
2. Edge cases
Brake caliper shape can be the limiter. Spoke design may clear or hit even if diameter looks fine.
Inner barrel clearance can get tight near the front strut and control arms with lower offsets or wider wheels.
Outer fender lip may rub during compression if width and offset push the tire out.
AWD sensitivity. Mismatched rolling diameters can stress the driveline in some cases. Keep front and rear diameters matched.
Hub bore matters. Wheels with a smaller bore than 66.6 mm will not seat. Larger bores need rings.
Lug seat style can differ. Some Audi use ball-seat OE hardware, while many aftermarket wheels require cone-seat. Mixing seats can loosen hardware.
Winter setups may need extra inner clearance for chains. Check chain maker guidance before downsizing.
3. Detection
Use the calculator on wheelinterchange.com to test fitment virtually before buying.
Set “Installed on (your vehicle)” to 2012 Audi S4.
Set “Wheels from (donor vehicle)” to the vehicle you want to borrow wheels from, or enter a “Custom wheel size.”
Adjust rim width and offset in small steps. Watch inner clearance and poke changes.
When you change rim diameter, the tool updates tire diameter in the comparison. Keep overall tire diameter close to baseline.
In the garage, do a dry test fit with no spacer first. Spin the wheel by hand. Check barrel-to-caliper clearance. Cycle steering from lock to lock. Compress the suspension slightly if possible and watch the fender lip.
4. Mitigations
Hub-centric rings. If an aftermarket wheel has a larger bore than 66.6 mm, use rings to center it.
Spacers. Small hub-centric spacers can recover caliper or strut clearance. You may need longer M14x1.5 hardware matched to spacer thickness.
Tire choice. A tire with a rounder shoulder can reduce rub at the fender. Stay mindful of load ratings.
Alignment. Modest camber within OEM tolerance can help clear the fender. Keep toe in spec.
Hardware seats. Match lug bolt seat type to the wheel seat. Do not reuse mismatched seats.
Do not force a smaller center bore on the hub. Do not mix front and rear tire diameters on AWD. Verify spacer hub bore is 66.6 mm and the wheel’s seat matches your bolts.
5. Safe defaults
Stay near the OEM 18x8 ET47 baseline while you learn the car’s clearances.
Keep overall tire diameter close to stock to avoid speedometer and driveline issues.
Use hub-centric rings whenever the wheel bore exceeds 66.6 mm.
Use quality M14x1.5 hardware with the correct seat for the wheel.
Torque to the OEM value and recheck after 50 to 100 miles.
6. Checklist
Confirm bolt pattern 5x112 and center bore 66.6 mm.
Match thread size M14x1.5 and correct seat type for the wheel.
Validate wheel width and offset in the calculator against the 2012 S4 baseline.
Check inner barrel and caliper clearance on a test fit.
Turn lock to lock and check fender clearance under compression.
Install with clean hub faces, hub-centric rings if needed, and proper torque.
Re-torque after short mileage. Monitor for vibration. Adjust as needed.
Always confirm seat type, length, and spacer thickness with the wheel maker and the calculator before purchase.
Final note
If anything in your setup feels uncertain, pause and compare it against the 2012 Audi S4 baseline in the calculator. Small changes can have big effects at the fender or the caliper. Take it step by step and you can land a clean, rub-free fit with confidence.
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.
