2009 Audi S6 Wheel Interchange

2009 Audi S6 Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2009 Audi S6

The following items are confirmed for at least one 2009 Audi S6 configuration. If a value varies by trim or package, use the on-page calculator and verify against your owner’s manual, the door-jamb label, and OEM documentation before purchasing.

Notes:

• The presence of both a 20 inch wheel and a 19 inch tire in the known data indicates multiple factory options may have existed. Confirm your specific setup with OEM sources and the on-page calculator before ordering.
• Lug seat style and factory torque are not provided. Inspect your existing bolts and consult the owner’s manual to confirm seat type and torque spec.

How To Use The Wheel Interchange Calculator

• Select Wheels from (donor vehicle) if you are comparing a takeoff set, or choose Custom wheel size to model aftermarket dimensions.
• Set Installed on (your vehicle) to 2009 Audi S6 to lock in hub bore and bolt pattern references.
• Enter wheel width and offset. The calculator instantly shows inner clearance and outer poke changes compared to your baseline.
• Adjust Custom tire size. When you change rim diameter, the calculator updates overall tire diameter in the comparison so you can keep speedometer error in check.
• Aim to keep overall tire diameter close to your stock reference. As a general guideline, try to stay within about 3 percent of stock overall diameter unless you have verified clearance and calibration.
• Review brake, strut, and fender clearances in the results. If anything appears marginal, measure your car and consult OEM data before buying.

Fitment Checklist Before You Buy

• Bolt pattern: Must be 5x112.
• Center bore: Vehicle hub is 57.1 mm. If the wheel bore is larger, plan for hub-centric rings with an inner diameter of 57.1 mm.
• Thread size: M14 x 1.5. Verify lug bolt seat style on your existing wheels before purchasing bolts.
• Wheel width and offset: Use the calculator to check inner clearance to the strut and outer poke to the fender. Even small offset changes can affect rubbing and steering feel.
• Brake caliper clearance: The S6 has large brakes. Physically test or confirm with the wheel manufacturer that spoke design clears the calipers.
• Overall tire diameter: Keep close to your baseline to minimize speedometer error and avoid rubbing. Check full lock-to-lock and compression clearance.
• Load rating: Wheels and tires must meet or exceed the vehicle’s axle and GVWR requirements.
• TPMS compatibility: Verify sensor type and frequency, and plan for coding or relearn as needed.
• Hardware: If you change wheel thickness or add spacers, you may need different-length wheel bolts. Use only high-quality, properly seated hardware.
• Returns and test-fit: Buy from a source that allows a protected test-fit before mounting tires whenever possible.

Plus Sizing And Common Upgrades

Using the known tire example 265/35R19, the overall diameter is approximately 26.3 inches. The calculator can help you find close matches when moving to a different wheel diameter.

• Example 20 inch options that keep diameter near 26.3 in:
  • 265/30R20 is about 26.3 in
  • 255/30R20 is about 26.0 in
  • 275/30R20 is about 26.5 in
• Wider tires may require different offsets and careful fender and inner clearance checks.
• If spacers are considered, use hub-centric spacers sized to the vehicle hub of 57.1 mm and lengthen wheel bolts appropriately. Recalculate effective offset in the calculator.
• Always confirm with OEM documentation and a physical test-fit before finalizing.

Installation Tips

• Park on level ground, use a proper jack and stands, and chock wheels.
• Clean the hub face and center pilot with a wire brush. Remove rust and debris to ensure the wheel sits flush.
• Dry-fit the front wheel first to verify caliper and spoke clearance. Rotate by hand and check at full steering lock.
• Use a wheel hanger guide pin for easier mounting on the Audi’s wheel bolts.
• Install bolts by hand, ensuring correct seat type engagement. Do not lubricate threads unless the manufacturer specifically instructs it.
• Tighten in a star pattern and torque to the value in your Audi owner’s manual. Recheck torque after 50 to 100 miles.
• If using hub-centric rings, ensure they are fully seated on the hub and inside the wheel bore before torquing.
• Perform an alignment check if you changed wheel width or offset to maintain proper handling and tire wear.

FAQs

• Does the 2009 Audi S6 use wheel bolts or studs?

  It typically uses wheel bolts. The thread size provided here is M14 x 1.5. Confirm your bolt seat style before buying new hardware.

• Will 20 inch wheels fit my 2009 S6?

  One known OEM wheel spec is 20 x 9.0 ET48, which indicates that a 20 inch factory option existed. Fitment can vary by package and brake setup. Use the calculator to confirm inner and outer clearances and verify against your specific car.

• What offset change is acceptable?

  There is no single number that fits all cases. Small changes can have big effects. Use the calculator to check inner clearance to the strut and outer poke to the fender, and physically measure your vehicle before purchasing.

• Do I need hub-centric rings?

  If your new wheel has a larger center bore than 57.1 mm, use rings with a 57.1 mm inner diameter to center the wheel on the hub. The outer diameter must match the wheel bore. If the wheel bore is exactly 57.1 mm, rings are not needed.

• What tire sizes keep my speedometer close to stock?

  Use the calculator starting from a known baseline such as 265/35R19 and aim to keep overall diameter similar. The tool will display percentage change and speedometer impact.

• Can I run spacers?

  Only if needed to correct clearance and with proper hub-centric spacers sized to 57.1 mm at the hub. You may need longer wheel bolts and must recalculate effective offset in the calculator. Always test-fit and torque properly.

• What is the correct torque for the wheel bolts?

  The exact torque is not provided here. Refer to your owner’s manual or Audi service documentation. Torque in a star pattern and recheck after 50 to 100 miles.

• Will wider tires affect rubbing or handling?

  They can. Wider sections change both inner and outer clearance and may require offset changes. Model the setup in the calculator and verify physically at full lock and over bumps.
