tl;dr
2023 Audi S8 – known OEM facts: bolt pattern 5x112, center bore 66.5 mm, thread size M14 x 1.5. Rim diameter, rim width, offset, backspacing and tire sizes are not provided here. Use the on-page calculator and OEM placard or dealer to confirm those unknowns before buying wheels. This page helps you identify, evaluate, and confirm fitment safely.
Recommendation
Start by confirming OEM wheel and tire specs. Use the calculator to test any donor wheel or custom size. Prioritize center bore, bolt pattern, thread size, offset, and brake clearance. If values are unknown, consult the door placard, owner manual, or dealer. When fitting aftermarket wheels, choose hub-centric rings if needed and aftermarket lug nuts matched to M14 x 1.5.
Impact
Correct fitment preserves safety, handling, and warranty coverage. Proper bolt pattern and thread size let you physically mount wheels. Correct center bore ensures hub-centric alignment. Proper offset and width affect scrub radius, steering feel, and fender clearance. Correct tire diameter keeps speedometer and ABS calibration close to OEM.
Risks
- Clearance: Wrong offset can contact calipers or inner arches.
- Brake interference: Large wheels can foul big calipers.
- TPMS and sensors: Aftermarket wheels may need OEM sensors transferred or matched replacements.
- Speedo/ABS: Tire diameter changes affect speedometer and ABS readings.
- Load rating: Wheels and tires must meet vehicle load requirements.
- Lug fitment gotcha: Thread size is M14 x 1.5; confirm seat type and torque spec.
Next actions
Follow this checklist and next steps. Work through them in order to save time and avoid returns.
- Check the door placard and owner manual for OEM wheel/tire specs.
- Use the on-page calculator: compare donor wheels vs installed on your S8.
- Enter custom wheel size: set rim diameter, width, and offset to test clearances.
- Enter custom tire size if you plan to change diameter or profile.
- Confirm hub bore and bolt pattern match; if bore >66.5 mm use hub rings.
- Confirm lug nuts: M14 x 1.5 thread pitch and correct seat type.
- Verify brake clearance by measuring caliper to mounting face or test-fit a single wheel.
- Check load rating and TPMS compatibility with the tire shop or wheel vendor.
- Tighten lug nuts to manufacturer torque spec after seating and re-torque after 50-100 miles.
OEM fitment summary (known vs unknown)
| Specification | Value |
|---|---|
| Bolt pattern (studs x PCD) | 5x112 |
| Center bore (mm) | 66.5 |
| Thread size | M14 x 1.5 |
| Rim diameter (in) | Unknown – confirm with placard/calculator |
| Rim width (in) | Unknown – confirm with placard/calculator |
| Wheel offset (ET, mm) | Unknown – confirm with placard/calculator |
| Backspacing (in) | Unknown – measure or calculate |
| Tire section width (mm) | Unknown – check OEM sizes |
| Tire aspect ratio (%) | Unknown – check OEM sizes |
| Tire rim diameter (R) | Unknown – check OEM sizes |
How to confirm unknown values
Use the on-page calculator to simulate wheel and tire combinations. Enter a donor wheel or custom wheel size to see clearance and diameter changes. For absolute confirmation, inspect the door placard, owner manual, or contact an Audi dealer with your VIN. Measure hub bore and wheel offset if buying used wheels.
Gotchas and practical tips
- Donor wheel fitment can vary by trim and brake package. Confirm before assuming compatibility.
- Center bore larger than 66.5 mm needs hub-centric rings to prevent vibrations.
- Mismatched lug seat type can damage wheels. Match seat geometry exactly.
- Changing rim diameter affects tire diameter; use the calculator to see net change.
- Always re-torque lug nuts after initial road miles. This is a simple safety step.
Useful parts (quick searches)
Hub rings and torque tools help with fitment and safe installation.
Next steps: use the on-page calculator now, confirm unknown specs from the placard or dealer, then pick wheels that match 5x112, 66.5 mm bore, and M14x1.5 thread. Follow the checklist above when fitting. That will minimize fitment issues and keep the car safe.
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
- Lug thread / hardware differences (vehicle-side hardware)
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.
