Donor vehicles with overlapping OEM specs
These are vehicle-year records whose recorded OEM ranges overlap this 2008 Audi A6. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 146 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)
Recorded OEM bolt pattern, center bore, and width/offset ranges overlap. This is not a guarantee that every wheel from the donor year fits this vehicle.
Wheel geometryOEM width/offset ranges overlap (not a specific wheel)
Approximate position vs the mid OEM package: outer change -12.85 mm, inner change 0.15 mm. This uses aggregated width/offset ranges, not a specific wheel.
Audi A6 Years With Compatible Wheels
Only years with evidence-based interchange relationships are listed. Adjacent years are not assumed compatible.

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
Access to the on-page fitment calculator.
Your current wheel and tire info from the driver door placard or owner’s manual.
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.
Spec
Value
Notes
Bolt pattern
5x112
All fasteners must match this PCD and 5-stud layout
Center bore
57.1 mm
Wheel bore must be 57.1 mm or larger with rings to 57.1
Thread size
M14 x 1.5
Match bolt thread and seat type to the wheel
Rim diameter
17 in
Known on some trims; see tire note below
Rim width
7.5 in
Known paired with ET45 on some trims
Wheel offset
ET45 mm
Baseline for clearance comparison
Backspacing
5.52 in
Derived from width and offset
Tire size
205/60 R16
Indicates 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
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.
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.
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.
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.
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.
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.
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
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.
