2011 Audi A6 Wheel Interchange

2011 Audi A6 Wheel Fitment Guide | wheelinterchange.com

Known OEM Fitment For 2011 Audi A6

These values reflect an OEM configuration for the 2011 Audi A6. Factory specs can vary by trim, brake package, and region. Always verify your exact specs using the calculator on this page, your door-jamb tire placard, the owner’s manual, or OEM parts information by VIN.

Reference tire diameter for 225/50R17 is approximately 25.9 in, which you can use as a baseline when plus-sizing. If your vehicle’s placard lists a different factory size, use that size in the calculator as your starting point.

How To Use The Wheel Interchange Calculator

The calculator lets you compare a donor wheel and tire to what will be installed on your 2011 Audi A6, and it updates tire diameter as you change rim diameter.

• Set Installed on (your vehicle) to 2011 Audi A6.
• For Wheels from (donor vehicle), pick the vehicle you are sourcing wheels from, or enter its specs. If you are evaluating aftermarket wheels, use Custom wheel size.
• Use Custom wheel size to change rim diameter, width, and offset. The calculator will show inner clearance to suspension and outer poke toward the fender.
• Use Custom tire size to set section width and aspect ratio. Changing rim diameter updates overall tire diameter in the comparison.
• Aim to keep overall tire diameter close to your baseline to maintain speedometer accuracy and gearing. Many installers target within about 3 percent, but always confirm clearances on your specific car.
• Review the results for:
  • Inner clearance change vs. struts and liners.
  • Outer poke vs. fenders and bumper.
  • Ride height change from tire diameter difference.
• Before purchasing, validate brake caliper clearance and hub bore compatibility, and confirm with OEM sources when in doubt.

Fitment Checklist Before You Buy

• Bolt pattern must be 5x112.
• Hub bore on the car is 66.6 mm. Aftermarket wheels with a larger bore require hub-centric rings sized to 66.6 mm.
• Thread size is M14 x 1.5. Confirm the lug seat style required by the wheel. Many Audi OE wheels use ball-seat bolts, many aftermarket wheels use cone-seat. Always match the lug seat to the wheel.
• Offset and width changes will shift the wheel in or out. Each 1 mm of offset change moves the wheel 1 mm. Increasing wheel width pushes half the added width inward and half outward. Use the calculator to visualize this on your A6.
• Brake clearance. Large calipers or rotor packages may require specific wheel designs. Test-fit or confirm with templates from the wheel maker.
• Tire overall diameter. Use your OE baseline, for example about 25.9 in for 225/50R17, and keep new setups close to maintain speedometer accuracy and avoid rubbing. Always verify in the calculator.
• Load index and speed rating must meet or exceed the factory ratings shown on your tire placard.
• TPMS. Plan to transfer sensors or install compatible new sensors and complete any required programming.
• Spacers if needed. Only use hub-centric spacers that match 66.6 mm hub. Longer, correct-seat bolts are required. If unsure, consult a professional.

Plus Sizing And Common Upgrades

Owners often consider larger wheel diameters for appearance and handling, while keeping overall tire diameter close to stock. The following are examples only, not guaranteed fitments. Always verify with the calculator and check on-car clearances.

• From 17 in baseline 225/50R17, example comparable diameters:
  • 18 in examples to evaluate: 245/40R18 or 255/40R18.
  • 19 in examples to evaluate: 245/35R19 or 255/35R19.
• Wider wheels and tires can improve grip but may require specific offsets to avoid rubbing. Confirm fender and liner clearance at full lock and full compression.
• Winter setups often use a narrower tire for better snow performance. Ensure brake clearance if downsizing wheels.

Installation Tips

• Clean the hub face and wheel mounting pad to remove rust and debris for proper seating. Do not lubricate lug bolt threads unless specified by the manufacturer.
• If the wheel bore is larger than 66.6 mm, install quality hub-centric rings sized to 66.6 mm.
• Hand-thread all bolts, then tighten in a star pattern. Torque to the factory specification from your owner’s manual or OEM service information.
• Use a wheel hanger or guide pin for easier mounting on M14 x 1.5 hubs.
• Re-torque the bolts after the first 50 to 100 miles of driving.
• If using spacers, ensure they are hub-centric and that you have the correct longer bolts with the proper seat style. Verify safe thread engagement and caliper clearance.
• After any significant wheel or tire change, have the alignment checked to maintain steering feel and tire life.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14 x 1.5 wheel hanger guide pin
• Hub-centric rings to 66.6 mm
• Tire pressure gauge

FAQs

• What is the bolt pattern for the 2011 Audi A6?

  5x112.

• What is the center bore size?

  66.6 mm. If an aftermarket wheel has a larger bore, use hub-centric rings sized to 66.6 mm.

• What lug bolt thread does it use?

  M14 x 1.5. Confirm the correct lug seat style for your wheels. Many OE Audi wheels use ball-seat bolts and many aftermarket wheels use cone-seat bolts. Do not mix seat types.

• What is an OEM wheel and tire setup for this model year?

  One OEM configuration is 17x7.5 ET45 with 225/50R17 tires, 5x112 bolt pattern, 66.6 mm hub bore, and M14 x 1.5 bolts. Trims and packages may differ, so verify your vehicle’s placard and use the calculator.

• Can I run 18 or 19 inch wheels?

  Often possible with the right offset and tire size, but not guaranteed. Use the calculator to keep overall diameter close to stock, check inner and outer clearances, and verify brake caliper clearance before purchasing.

• Do I need hub-centric rings?

  If your wheel’s center bore is larger than 66.6 mm, yes. Rings help the wheel center on the hub and reduce vibration. They do not replace the need for the correct lug seat style and proper torque.

• What does the 5.52 in backspacing mean?

  Backspacing is the distance from the wheel mounting face to the inner wheel lip. The listed 5.52 in corresponds to the OEM wheel noted above. If you change width or offset, backspacing will change, affecting inner clearance.

• What torque should I use on the lug bolts?

  Follow the factory torque specification from the Audi owner’s manual or OEM service information for your exact trim and brake package. Re-torque after the first 50 to 100 miles.
