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.

2015 Audi S6 Wheel Interchange and Fitment Guide

tl;dr

Use the OEM wheel and tire as your baseline. Match the 66.6 mm hub and M14x1.5 bolts. Verify offset and width with the calculator before you buy. Test fit and check clearances at full lock and full compression.

Known OEM fitment for 2015 Audi S6

These values reflect a documented factory setup for this model year. Trims and regional packages can vary. If your car differs, use the on-page calculator and confirm against your owner manual and dealer parts data.

Spec Value Notes
Bolt pattern 5x112 5 studs on a 112 mm circle
Center bore 66.6 mm Wheel must seat on this hub diameter
Thread size M14 x 1.5 Uses lug bolts, not nuts
Wheel size 19 x 8.5 Diameter x width in inches
Offset ET45 Positive 45 mm
Backspacing 6.02 in From hub face to wheel inner lip
Tire size 255/40R19 Approx diameter ~27.0 in

Recommendation

Start from the OEM baseline above. Keep the hub bore at 66.6 mm for hub-centric mounting. Match M14x1.5 bolt thread and the correct seat type for your wheel. Use the calculator to compare any donor wheel or custom setup against your S6. Keep overall tire diameter close to stock for speedometer and ABS behavior.

Impact

  • Offset change: Lower ET pushes the wheel outward. Higher ET pulls it inward. This affects fender and suspension clearance.
  • Width change: Wider wheels add inner and outer poke. Inner side risks strut and liner contact.
  • Diameter change: Tire diameter alters ride height and speedometer. Large changes can upset gearing and ABS tuning.
  • Center bore: Larger bores need rings to 66.6 mm. Smaller bores will not fit.
  • Fasteners: Spacers or thicker pads may require longer M14x1.5 bolts. Seat style must match the wheel seat.
  • Brake clearance: Spoke design matters. Caliper clearance is not guaranteed by diameter alone.

Risks and gotchas

  • Unknown trim differences: Brake packages and suspension can vary. Confirm your exact trim with OEM sources if unsure.
  • Rubbing under load: Clearance at static ride height can be misleading. Check at full lock and over a bump.
  • Wrong seat type: Audi OEM wheels often use ball seats. Many aftermarket wheels use cone seats. Mismatch can loosen or damage seats.
  • Hubcentric vs lugcentric: Do not rely on bolts to center the wheel. Use 66.6 mm hub-centric fit or rings.
  • Spacer use: Quality, hubcentric spacers only. Verify hub lip engagement and bolt length.
  • Torque and sequence: Use star pattern and factory torque spec from your manual. Do not guess the torque.
  • TPMS: Sensor compatibility and relearn methods vary. Plan for sensor swap or coding if needed.

How to use the calculator on wheelinterchange.com

Plan

  • Set Installed on to 2015 Audi S6 with the OEM baseline shown above.
  • Set Wheels from to your donor vehicle or aftermarket option.

Compare wheels

  • Enter the donor wheel diameter, width, and offset.
  • Review Inner clearance and Outer poke changes. Aim to keep inner clearance positive and outer poke within the fender line.

Dial in tires

  • Adjust Custom tire size to maintain overall diameter near the OEM ~27.0 in.
  • Watch speedometer error and ride height change on the output.

Decide

  • If inner clearance is tight, consider a slightly lower ET or a small spacer. Verify hub engagement.
  • If outer poke exceeds the fender, consider higher ET or a narrower wheel or tire.

Install checklist

  • Confirm hub bore 66.6 mm or use rings sized to 66.6.
  • Confirm bolt thread M14x1.5 and seat type matches wheel.
  • Clean hub face. Remove rust ridges. Measure hub lip engagement.
  • Dry fit one front and one rear. Spin check and hand-turn full lock both ways.
  • Torque to the Audi spec from your manual with a calibrated wrench.
  • Road test. Re-torque after 50 to 100 miles.

Next actions

  1. Identify your exact trim and brake package. If uncertain, cross-check with your VIN at an Audi parts counter.
  2. Open the calculator and input the OEM values above as your Installed on baseline.
  3. Enter the donor or custom wheel specs. Evaluate inner and outer clearance.
  4. Set a matching tire size that keeps diameter near ~27.0 in.
  5. Decide on rings, spacers, and correct bolts if needed.
  6. Test fit, then complete installation using proper torque and sequence.

Notes on variability

Factory equipment can differ by market, package, or prior owner changes. If any value on your car does not match the table, prioritize your actual measurements and OEM documentation. Use the calculator to validate any alternate setup before purchase.

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.
