Known OEM Fitment For 2006 Audi A6

The values below are provided data points for the 2006 Audi A6. Audi offered multiple wheel and tire packages in 2006, so equipment can vary by trim, brakes, market, and options. If your vehicle differs, use the calculator on this page and verify against your door-jamb tire placard, the owner’s manual, or an Audi parts catalog by VIN.

Bolt pattern (studs x PCD)5x112
Center bore (mm)57.1
Thread sizeM14 x 1.5
Known OEM rim diameter (in)17
Known OEM rim width (in)7.5
Known OEM offset ET (mm)45
Known OEM backspacing (in)5.52
Known OEM tire size example205/60R16

Notes:

  • The presence of both a 17x7.5 ET45 wheel and a 205/60R16 tire size indicates multiple OEM packages in 2006. Confirm what your specific car shipped with before using it as a baseline.
  • Brake package size can affect the minimum wheel diameter that will clear the calipers.
  • If any of your values are unknown, confirm them with the calculator and OEM sources listed above.

How To Use The Wheel Interchange Calculator

  • Set Installed on (your vehicle) to 2006 Audi A6. This locks your target bolt pattern, hub bore, and baseline dimensions for comparisons.
  • Choose Wheels from (donor vehicle) or enter a Custom wheel size if you already have specs for potential wheels.
  • Adjust Custom tire size if you are evaluating a different tire. When you change rim diameter, the tool updates the overall tire diameter in the comparison so you can see the effect on ride height and speedometer.
  • Review clearance changes. The calculator shows inner clearance to suspension, outer poke toward the fender, and tire diameter difference.
  • Aim to keep tire overall diameter close to your verified OEM size for accurate speedometer and to maintain ABS and stability control behavior.
  • If you see reduced inner clearance or increased outer poke, measure your car. Turn the steering from lock to lock and check fender and liner clearances before you buy.

Fitment Checklist Before You Buy

  • Bolt pattern: Must be 5x112. Do not use wobble bolts or adapters unless you fully understand the safety implications.
  • Center bore: Vehicle hub is 57.1 mm. Aftermarket wheels often have a larger bore. Use quality hub-centric rings to step down to 57.1 mm if needed. Never force a smaller bore onto the hub.
  • Offset and backspacing: Compare the candidate wheel to your verified OEM baseline. Keep inner clearance to struts and control arms, and avoid excessive fender poke. Use the calculator to visualize both.
  • Brake clearance: Physically test fit or confirm with the wheel seller that the spoke design and barrel clear your calipers. Minimum diameter can vary by brake package.
  • Hardware: Match seat type (ball vs cone) to the wheel, and match thread size M14 x 1.5. Ensure full and safe thread engagement equivalent to factory. If spacers are used, use hub-centric spacers and appropriate extended hardware.
  • Load rating: Wheel and tire load index must meet or exceed the vehicle’s axle loads. Check the tire placard and manufacturer specs.
  • TPMS: Sensor type and frequency can vary by market and equipment level. Reuse or program compatible sensors when changing wheels.
  • Tires: Keep overall diameter close to OEM to protect speedometer accuracy and drivability. Verify inner and outer clearance at full steering lock and under compression.
  • Speed, balance, and vibration: Any wheel with a larger center bore must be centered with hub rings to avoid vibration. Always road-force balance tires if possible.

Plus Sizing And Common Upgrades

Enthusiasts often consider plus sizing for appearance and handling. The exact sizes that fit can vary by brake package, suspension height, and alignment. Use these as planning guidelines only, then confirm with the calculator and a physical check on your car.

  • Plus 1: If your verified baseline is a 16 inch tire like 205/60R16, you might evaluate a 17 inch wheel with an appropriate tire to keep overall diameter near stock. Use the calculator to select a tire that matches overall height.
  • Plus 1 from 17 inch: If your verified baseline is 17x7.5 ET45, you can evaluate an 18 inch wheel and tire combination while maintaining similar overall diameter and offset. Confirm inner and outer clearances, especially near the strut and fender lip.
  • Wider wheels: Wider wheels can improve grip but reduce inner clearance. The calculator will show inner clearance loss and outer poke. Measure your actual clearances before committing.

Important: Do not assume a particular plus size will clear your brakes or fenders. Always verify on your specific car.

Installation Tips

  • Test fit each wheel without a tire first if possible. Spin the hub and check caliper and spoke clearance.
  • Clean hub faces and the wheel mounting pad. Remove rust and debris to ensure the wheel sits flush.
  • Use correct hub-centric rings if the wheel bore is larger than 57.1 mm. The wheel should center snugly on the hub.
  • Match lug hardware seat type to the wheel and confirm thread size M14 x 1.5.
  • Tighten hardware by hand first, then torque in a star pattern to the factory specification from your owner’s manual or service manual. Re-torque after 50 to 100 miles.
  • Verify brake line and ABS wire clearance after installation. Turn lock to lock and compress the suspension if possible.
  • Check tire pressures to the door-jamb placard values and perform a road-force balance to minimize vibration.

Tools And Helpful Supplies

FAQs

  • Will wheels from another Audi fit my 2006 A6?

    Start by matching bolt pattern 5x112 and ensuring the center bore is 57.1 mm or that you can use rings to 57.1. Enter the donor wheel specs in the calculator and compare offset and width to your verified OEM baseline. Physically check brake and fender clearance before purchase.

  • Can I run 18 or 19 inch wheels?

    Often possible, but it depends on your brake package, offset, and tire selection. Use the calculator to keep overall tire diameter near your OEM size and verify inner and outer clearances. Do not assume large diameters will clear all calipers.

  • Do I need hub-centric rings on aftermarket wheels?

    If the wheel’s center bore is larger than 57.1 mm, use quality hub-centric rings to 57.1 mm for proper centering. If the wheel bore is exactly 57.1 mm and fits cleanly, rings are not required.

  • What lug nut or bolt type do I need?

    Match thread size M14 x 1.5 and the correct seat profile required by the wheel (ball or cone). Use hardware of appropriate length to achieve safe, factory-equivalent thread engagement. If spacers are installed, use hardware designed for the added thickness.

  • What is the correct torque spec for the A6?

    Torque values can vary. Always use the specification in your owner’s manual or an Audi service manual for your VIN. Torque in a star pattern and re-check after 50 to 100 miles.

  • My placard shows a different OEM tire size than 205/60R16. Is that normal?

    Yes. The 2006 A6 was available with multiple wheel and tire packages. Use your door-jamb placard or manual as your primary reference, set that as the baseline in the calculator, and compare any candidate setups against it.

  • Will 16 inch wheels clear my brakes for winter tires?

    Brake package sizes can differ, and minimum clearing diameter varies. Some setups may require 17 inch or larger. Test fit or confirm with the wheel seller using your VIN, and verify with the calculator and a physical clearance check.
