Wheel Fitment Parts for the 2017 Audi A6

Products below are matched to required fitment dimensions from our parts inventory. Confirm seat style, thickness, and clearance before ordering.

Lug Nuts / Wheel Bolts

M14 x 1.5

Wheel Adapters

5x112 · 66.5 mm hub

Directional bolt-pattern adapters. A spacer does not change PCD.

Why These Wheels Fit

Wheel interchange depends on more than bolt pattern. Where data is available, this site compares:

  • 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.

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.

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.
