Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2017 Audi A6. 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.

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 -1.17 mm, inner change -5.18 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; they cannot enlarge a smaller bore. 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.

2017 Audi A6 wheel fitment guide
tl;dr
Known factory specs for this A6: 5x112 bolt pattern, 66.6 mm center bore, M14 x 1.5 threads. One documented wheel is 19x8.5 ET45 with about 6.02 in backspacing. A documented tire is 245/45R18. Those tire and wheel diameters do not match, which suggests multiple factory packages. Do not mix 18 inch tires with 19 inch wheels. Confirm your exact setup using the tire placard and the on-page calculator.
Recommendation
I recommend a simple, staged approach.
- Identify your baseline. Read the door placard for tire size. Check the wheel for an ET stamp and size castings.
- Lock in the non-negotiables: 5x112 bolt pattern, 66.6 mm center bore, M14 x 1.5 bolts.
- Use the calculator. Set “Installed on” to your 2017 A6. Enter your current wheel and tire. Compare against any “donor” wheel or a custom size.
- Keep rim and tire diameters matched. 18 inch tire sizes mount on 18 inch wheels only. 19 inch tires mount on 19 inch wheels only.
- If you choose 19x8.5 ET45, that matches a known spec. Verify tire size and fender clearance in the calculator before buying.
- If your placard shows 245/45R18, use an 18 inch wheel. Do not mount that tire on a 19 inch rim.
- Stay hub-centric. If an aftermarket wheel has a larger bore, use rings to 66.6 mm.
- Match fasteners to the seat type of the wheel. Confirm seat style with the wheel supplier before purchase.
Impact
Each change affects clearance and dynamics.
- Offset changes move the wheel inward or outward. Use the calculator to visualize strut clearance and poke.
- Width changes affect inner clearance and fender lip space. Small changes can matter on full lock or big bumps.
- Tire overall diameter changes affect speedometer and gearing. The calculator updates this as you change tire size.
- Centering quality affects vibration. Hub-centric fit to 66.6 mm reduces shake at highway speeds.
- Fastener geometry affects safety. Correct thread (M14 x 1.5) and seat shape are critical.
Risks
- Mismatched wheel and tire diameter. This leads to mounting refusal or bead failure.
- Wrong offset causing rub on struts, liners, or fenders. Always simulate in the calculator, then test fit.
- Incorrect center bore. Too small will not seat; too large needs rings.
- Wrong bolt seat or length. This can loosen or damage hubs and rotors.
- Using spacers without appropriate longer bolts. Thread engagement must meet OEM guidance.
- Brake caliper clearance issues with certain spoke designs. Check a physical test fit before driving.
- Assuming all trims share specs. Some packages differ. Confirm by VIN, placard, or OEM documentation.
Known OEM fitment snapshot
| Parameter | Spec | Notes |
|---|---|---|
| Bolt pattern | 5x112 | 5 studs, 112 mm PCD |
| Center bore | 66.6 mm | Hub-centric target size |
| Thread size | M14 x 1.5 | Verify seat type for your wheels |
| Wheel size | 19 x 8.5 | Documented factory package |
| Offset (ET) | 45 mm | Use as reference in the calculator |
| Backspacing | 6.02 in | Derived from width and offset |
| Tire size | 245/45R18 | Documented factory tire on an 18 inch wheel |
Note: The listed 19 inch wheel and 18 inch tire reflect different packages. Confirm your car’s exact package with the door placard and wheel markings.
Next actions
- Checklist:
- Read your placard tire size and load index.
- Record current wheel width, diameter, and ET from the casting.
- Open the on-page calculator. Set “Installed on” to 2017 Audi A6.
- Enter your current setup. Compare to the donor or custom size.
- Confirm hub bore is 66.6 mm or plan hub-centric rings.
- Confirm M14 x 1.5 bolts and correct seat type for the wheel.
- Simulate clearance. Aim to avoid inner rub and outer poke.
- Order parts. Test fit one corner. Spin the wheel and check lock-to-lock.
- Torque to the OEM spec only. Re-torque after 50–100 miles.
- Helpful tools and parts:
Gotchas
- Do not assume spacer thickness fixes every rub. Clearances vary by tire brand and profile.
- Wheel studs vs bolts. This Audi uses bolts. Plan hardware accordingly.
- Seat mismatch is common with aftermarket wheels. Verify ball or cone seat before driving.
- TPMS details can vary by market. Relearn as per the owner’s manual.
Closing note
If a spec is missing or varies by trim, rely on the door placard, the wheel castings, and the calculator comparison. Keep the non-negotiables correct, and test fit before final mounting. That keeps the 2017 A6 safe, smooth, and precise.
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.
