Dataset suggestionHub-centric rings ≈ 66.5 → 57.1 mm – not a verified installation requirement.

See matching hub rings

Hub-centric rings of about 66.5 → 57.1 mm mm may be relevant if the wheel bore is larger than the hub; they cannot enlarge a smaller bore.

2008 Audi A6 wheel fitment - practical guide

You want wheels that bolt up, clear the brakes, and drive safely. The challenge is that the 2008 Audi A6 shipped with multiple factory setups, and our data for this year shows mixed tire and wheel sizes. We will start from what is known, confirm your exact baseline, and use the on-page calculator to validate any change before you buy or install.

Goal

Select and validate wheels and tires that fit a 2008 Audi A6 under real-world constraints, using the wheelinterchange.com calculator and OEM references to avoid rubbing, vibration, or unsafe hardware mismatches.

Prerequisites

Known OEM fitment for 2008 Audi A6 - partial baseline

The values below are confirmed for at least one trim. Tire and wheel sizes varied by market and package. Use these as a starting point and validate against your VIN and door placard.

SpecValueNotes
Bolt pattern5x112All fasteners must match this PCD and 5-stud layout
Center bore57.1 mmWheel bore must be 57.1 mm or larger with rings to 57.1
Thread sizeM14 x 1.5Match bolt thread and seat type to the wheel
Rim diameter17 inKnown on some trims; see tire note below
Rim width7.5 inKnown paired with ET45 on some trims
Wheel offsetET45 mmBaseline for clearance comparison
Backspacing5.52 inDerived from width and offset
Tire size205/60 R16Indicates some trims used 16 in wheels. Conflicts with the 17 in rim entry. Confirm your trim and door placard.

Assumption: Because both 16 in and 17 in baselines appear in OEM data for this year, confirm your exact factory size before planning any change.

Step by step

  1. Confirm your OEM baseline
    • Read the driver door placard for factory tire size and load index.
    • Check your current wheel’s inside barrel for stamped size, offset, and part number.
    • Verify 5x112 bolt pattern, 57.1 mm hub, and M14x1.5 hardware are present as expected.
  2. Open the calculator
    • Set Installed on to 2008 Audi A6.
    • If comparing a donor vehicle, select it under Wheels from. Otherwise, use Custom wheel size and Custom tire size to model your target setup.
    • When you change rim diameter, the calculator updates the compared tire diameter automatically. Use this to keep total diameter near your OEM baseline.
  3. Respect non-negotiables
    • Bolt pattern must be 5x112.
    • Center bore on the wheel must be 57.1 mm or larger. If larger, use hub-centric rings to 57.1 mm for vibration control.
    • Threads must be M14x1.5. Match seat type to the wheel design.
  4. Evaluate width and offset trade-offs
    • Use the calculator’s inner clearance and outer poke deltas to compare against the ET45, 7.5 in baseline.
    • More negative offset pushes the wheel outward and reduces inner clearance. More positive offset tucks inward and risks strut or liner contact.
    • Wider wheels add both inner and outer width. Watch both sides in the calculator.
  5. Choose a compatible tire size
    • Start from your door placard size if stock, or from your confirmed OEM baseline.
    • Aim to keep overall tire diameter within a small percentage of OEM for speedometer and ABS behavior. Use the calculator to see the percent change.
    • Check that section width and shoulder shape will clear fenders at full lock and over bumps.
  6. Plan hardware
    • If using hub-centric rings, match wheel bore to 57.1 mm on the car.
    • Select bolts of correct length for the wheel thickness and any spacer used. Full thread engagement is recommended.
  7. Dry fit and measure
    • Test-fit one front and one rear. Spin by hand, turn lock to lock, and check caliper, strut, and liner clearance.
    • If using spacers, use hub-centric spacers and confirm hardware length again.

Validation

  • Calculator checks
    • Inner clearance is positive with a margin appropriate to your usage.
    • Outer poke will not exceed fender limits through suspension travel.
    • Tire overall diameter

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.
