Known OEM Fitment For 2008 Audi S6

The data below reflects known specs for this model year. This list may be partial. Some wheel and tire values can represent different OEM packages. Do not combine wheel and tire rows as a single set without verifying with the calculator and OEM sources.

  • Bolt pattern: 5x112
  • Center bore: 57.1 mm
  • Thread size: M14 x 1.5

Known OEM wheel package:

  • Rim diameter: 20 in
  • Rim width: 9.0 in
  • Offset: ET 48 mm
  • Backspacing: 6.39 in

Known OEM tire size on another package:

  • Tire size: 265/35R19

Note: The 20 inch wheel listing and the 19 inch tire listing likely refer to different factory packages. Use the calculator to match a correct tire to your wheel size and confirm against OEM documentation for your VIN.

How To Use The Wheel Interchange Calculator

  • Set Installed on (your vehicle) to 2008 Audi S6. This locks the baseline geometry for your car.
  • Choose Wheels from (donor vehicle) to compare another vehicle’s stock setup to your S6.
  • Or use Custom wheel size to test a specific rim diameter, width, and offset. The tool will show inner clearance to suspension and outer poke versus your baseline.
  • Use Custom tire size to enter section width and aspect ratio. When you change rim diameter, the calculator updates overall tire diameter in the comparison so you can keep speedometer error in check.
  • Watch the inner clearance number for interference with struts and control arms, and the outer position for fender and liner contact. Check brake caliper clearance visually as well.
  • Aim to keep overall tire diameter close to your OEM package and verify with your owner’s manual and OEM parts catalog before you buy.

Fitment Checklist Before You Buy

  • Pattern and hardware: 5x112 bolt pattern and M14 x 1.5 threads. Confirm your lug seat style by inspecting an OEM bolt head and the wheel seat surface before ordering replacement bolts.
  • Hub bore: Your hub is 57.1 mm. If an aftermarket wheel has a larger center bore, plan for hub centric rings to 57.1 mm.
  • Offset and backspacing: Compare the candidate wheel’s ET and backspacing to the known OEM values above using the calculator. Verify both inner clearance and outer fender position under full steering lock and suspension compression.
  • Brake clearance: The S6 has large brakes. Test-fit or confirm with a template from the wheel manufacturer that spoke and barrel clear the calipers.
  • Tires: If changing wheel diameter, use the calculator to select a tire that keeps overall diameter close to your OEM package. Check load index and speed rating that meet or exceed OEM.
  • TPMS: System type can vary by market and build. Inspect your current setup and follow your owner’s manual for sensor compatibility and relearn procedures.
  • Spacers and adapters: Use only hub-centric parts that match a 57.1 mm hub and ensure proper bolt length and thread engagement. Check local regulations.
  • Documentation: Verify part numbers and specifications with an Audi dealer or OEM catalog using your VIN if anything is unclear.

Plus Sizing And Common Upgrades

The known OEM tire size listed is 265/35R19, and a separate OEM wheel package is listed at 20x9 ET48. If you plan to move between 19 and 20 inch packages, use the calculator to select a tire size that closely matches the original rolling diameter for proper ABS, traction control, and speedometer behavior.

  • All wheel drive note: A square setup is recommended so all four tires match in size and wear.
  • Keep offset sensible: Pushing wheels outward too far can increase fender contact risk and wheel bearing load. Verify with the calculator and a physical test-fit.
  • Hub-centric is best: Use wheels with a 57.1 mm bore or quality hub rings to that size for smooth highway driving.
  • Ride and clearance: Lower profile tires from plus sizing can reduce ride comfort and snow performance. Ensure enough inner and outer clearance at full lock and full bump.

Installation Tips

  • Clean the hub: Remove rust and debris from the 57.1 mm hub face and center pilot. A clean, flat mounting surface prevents vibration.
  • Dry fit first: Test a front and rear wheel without tires when possible to confirm caliper and spoke clearance.
  • Lug bolts: Hand start all M14 x 1.5 bolts. Do not use an impact to start threads. Tighten in a star pattern and finish with a torque wrench to the value in your owner’s manual.
  • Thread engagement: Ensure full and proper thread engagement when using spacers or different bolt lengths. Use only the seat style that matches your wheel.
  • Hub rings: If needed, install snug-fitting rings to 57.1 mm before mounting the wheel.
  • Recheck: After initial driving, recheck torque and inspect for any rubbing under load and steering lock.

Tools And Helpful Supplies

FAQs

  • What is the bolt pattern on the 2008 Audi S6?

    5x112.

  • What center bore does it use?

    57.1 mm.

  • What is the thread size for the lug bolts?

    M14 x 1.5.

  • Is 20x9 ET48 an OEM fitment?

    It is listed in our known OEM data. Tire size and other packages can vary, so confirm with the on-page calculator and your Audi dealer using your VIN.

  • Can I use a wheel with a 5x114.3 pattern?

    Not directly. Adapters would be required, which add complexity and change fitment. Using the correct 5x112 wheels is recommended.

  • Do I need hub centric rings?

    Only if your aftermarket wheel has a larger center bore than 57.1 mm. Choose quality rings that reduce to 57.1 mm.

  • What tire size should I run on 20 inch wheels?

    Use the calculator to select a tire that keeps overall diameter close to your OEM package. Cross check with OEM guidance for your VIN. Do not rely on guesses.

  • What lug seat style does the S6 use?

    Many Audis of this era use ball-seat lug bolts, but this can vary by wheel. Inspect your existing bolts and wheel seats or confirm via OEM parts sources.

  • What torque should I use on the lug bolts?

    Refer to your owner’s manual or OEM service information for the correct torque. Do not over-tighten. Always finish with a torque wrench.

  • Will spacers help flush the wheels?

    Possibly, but verify hub-centric fit to 57.1 mm, adequate thread engagement with longer bolts if required, and clearance using the calculator and a physical test-fit.

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.
