2014 Audi S6 Wheel Interchange

2014 Audi S6 Wheel Fitment, Bolt Pattern and Offset Guide | wheelinterchange.com

Known OEM Fitment For 2014 Audi S6

The values below are the confirmed factory specifications provided for the 2014 Audi S6. Other factory packages may exist and can vary by trim and brake package. If your vehicle differs, verify using the on-page calculator and your OEM sources such as the owner manual, service information, or the door jamb tire label.

Do not assume interchange solely from bolt pattern. Brake caliper clearance, hub bore, offset, load rating, and lug seat type must be correct for safe installation.

How To Use The Wheel Interchange Calculator

• Open the calculator on this page. In Wheels from select the donor vehicle or enter a Custom wheel size. In Installed on select 2014 Audi S6.
• Start from the known OEM baseline above. Enter 19 x 8.5 ET45 with 255/40R19 as your current setup.
• Adjust Custom wheel size to test new rim diameter, width, and offset. Adjust Custom tire size to keep overall tire diameter within a reasonable range. The calculator updates tire diameter automatically when rim diameter changes.
• Review the results:
  • Inner clearance change: space to strut and liners. More positive offset moves the wheel inward. Less positive offset moves it outward.
  • Outer poke change: how far the wheel sits toward the fender edge.
  • Overall tire diameter and speedometer change: aim to stay close to stock to preserve gearing, ABS, and driver assists.
• Brake caliper and barrel clearance are critical on the S6. Use the calculator to estimate, then confirm physically:
  • Ask the wheel seller for a brake template for the 2014 S6, or perform a test fit.
  • Measure with a straightedge across the hub face and a ruler to check spoke-to-caliper and barrel clearance.
• Before purchase, verify hub bore, lug seat style, and load rating. If a donor wheel has a larger center bore than 66.6 mm, hub-centric rings are recommended. If the bore is smaller than 66.6 mm, the wheel will not fit without machining.

Fitment Checklist Before You Buy

• Bolt pattern: 5x112 must match.
• Center bore: vehicle hub is 66.6 mm. Wheels with larger bores can be hub-centered with rings. Smaller bores will not fit.
• Thread size: M14 x 1.5. Confirm lug bolt seat type matches the wheel design. Do not mix ball seat with cone seat.
• Offset: OEM is ET45. Use the calculator to model inner clearance and poke when changing ET. Verify fender and suspension clearances at full lock and full compression.
• Backspacing: 6.02 in for the OEM 19 x 8.5 ET45. Compare any new wheel backspacing to ensure inner clearance.
• Brake clearance: the 2014 S6 has large calipers. Not all 19-inch wheel designs clear. Always test fit or confirm with a brake template from the seller.
• Tire load and speed ratings: meet or exceed the OEM ratings shown on the door label.
• TPMS: ensure sensor compatibility and plan for programming if needed.
• Suspension height: lowering springs or coilovers reduce clearance. Re-check with the calculator and measure on the car.
• AWD considerations: keep rolling diameters very close front to rear to protect the quattro drivetrain.

Plus Sizing And Common Upgrades

Plus sizing changes wheel diameter and tire profile while keeping total tire diameter close to stock. For drivability and AWD health, try to keep overall diameter within about plus or minus 3 percent of stock, and keep front to rear diameters effectively equal.

• OEM reference: 255/40R19 is approximately 27.03 in overall diameter.
• Example for a 20-inch upgrade: 255/35R20 is also about 27.03 in overall diameter. This maintains gearing and speedometer closely. This is an example only, not a guarantee of brake or fender clearance. Use the calculator and confirm physically.
• Changing offset example: moving from ET45 to ET40 pushes the wheel outward by 5 mm and reduces inner clearance by 5 mm. Use the calculator to visualize these changes against your car.
• Width changes: increasing wheel width adds half the change to both inner and outer edges before offset adjustments. Combine width and offset changes in the calculator to balance clearance.
• Square setups are recommended for rotation on AWD. Staggered widths or diameters can affect handling balance and AWD load unless rolling diameters remain equal. If you experiment, verify circumference match front to rear within a very tight tolerance.

Installation Tips

• Safety first: support the vehicle with quality jack stands on solid ground. Use proper jacking points.
• Clean the hub face and wheel mounting pad. Lightly remove rust with a wire brush. A thin smear of anti-seize on the hub centering lip only can help prevent sticking. Keep threads clean and dry unless OEM procedures specify otherwise.
• If using hub-centric rings, seat them fully on the wheel before mounting. Verify they match 66.6 mm at the hub side.
• Hand start all lug bolts to avoid cross-threading. If your Audi uses lug bolts, a wheel hanger guide pin helps align the wheel.
• Torque in a star pattern with a calibrated torque wrench. Use the torque value from your Audi owner manual or service information. Re-torque after 50 to 100 miles.
• Spacers, if used, must be high quality and hub-centric. Longer lug bolts with correct seat type are required. Verify full thread engagement per hardware manufacturer guidance.
• After any fitment change, check lock-to-lock steering and compress the suspension to confirm no rubbing on liners, brake hoses, or fenders.
• Schedule an alignment if you changed wheel width, offset, or ride height.

Tools And Helpful Supplies

• 1/2 inch torque wrench
• Wheel hanger guide pin M14x1.5
• M14x1.5 lug bolts ball seat or the correct seat type for your wheels
• 66.6 mm hub centric rings if your new wheels have a larger bore

FAQs

• What is the bolt pattern for the 2014 Audi S6?

  5x112.

• What center bore does the 2014 S6 use?

  66.6 mm. Use hub-centric rings if your wheels have a larger bore. Wheels with a smaller bore will not fit.

• What is the OEM wheel size and offset?

  19 x 8.5 ET45 with 6.02 in backspacing. Other factory options may exist. If your car differs, confirm via your door label, owner manual, or VIN lookup and use the calculator to compare.

• What lug hardware does it use?

  M14 x 1.5 lug bolts. Match the lug seat style to the wheel design. Do not mix ball-seat and cone-seat hardware.

• Will 20-inch wheels fit my 2014 S6?

  Fitment depends on wheel design, offset, width, and brake clearance. As an example only, 255/35R20 has a very similar overall diameter to the OEM 255/40R19, but you must verify brake and fender clearance with the calculator and a physical test fit.

• Can I use wheels from another 5x112 vehicle like Mercedes or VW?

  Sometimes, but not guaranteed. You must match bolt pattern, center bore, offset, load rating, brake clearance, and lug seat type. Always model in the calculator and confirm physically.

• What wheel offset range is safe?

  This varies with wheel width, tire size, and brake or suspension setup. Use the calculator to see inner clearance and outer poke changes from the OEM ET45 baseline, then measure on the car.

• Do I need an alignment after changing wheels or tires?

  Recommended if you changed wheel width, offset, or ride height. An alignment helps prevent uneven wear and maintains handling.

• What torque should I use on the lug bolts?

  Refer to the Audi owner manual or service information for the exact torque. Do not guess. Tighten with a calibrated torque wrench in a star pattern and re-torque after 50 to 100 miles.

• Is it safe to run staggered tires on quattro?

  A square setup is preferred. If you choose staggered widths, keep overall rolling diameters effectively equal front to rear to protect the AWD system. Verify with the calculator and tire manufacturer data.
