2014 Audi A7 Wheel Fitment and Interchange Guide

tl;dr

Your 2014 Audi A7 baseline is 5x112, 66.6 mm center bore, M14x1.5 bolts, 19x8.5 ET32 with 255/40R19 tires. Use the on-page calculator to compare any donor wheel against these numbers. Match hub bore, bolt pattern, and offset closely, then verify brake and fender clearance in person.

Known OEM baseline

Notes: Some trims and brake packages can differ. If your vehicle differs, confirm by VIN with an Audi parts counter and measure your current wheel markings.

Recommendation

I start with the OEM numbers above as the control. Then I compare any candidate wheel using the calculator on wheelinterchange.com. That shows inner clearance, outer poke, and tire diameter changes while you adjust width, offset, and tire size.

• Match bolt pattern exactly at 5x112.
• Hub bore must seat on 66.6 mm. Larger bores need hub-centric rings. Smaller bores do not fit without machining.
• Offset near ET32 keeps geometry familiar. Use the calculator to see how far you move in or out.
• Maintain or exceed the OEM tire load rating. Keep rolling diameter near stock to avoid speedometer error.
• Thread size is M14x1.5. Confirm seat type on the wheels and use matching lug bolts.

Impact

Changing width or offset shifts the wheel relative to suspension and fenders. More positive ET moves inward and risks strut or liner rub. Less positive ET pushes outward and risks fender contact or stone throw. Wider wheels stretch inward and outward together. Tire aspect changes affect ride height, speedometer, and gearing feel. The calculator updates tire diameter as you change rim size to help you stay close to stock.

Risks

• Incorrect hub bore causes vibration. Always seat on 66.6 mm with proper rings if needed.
• Wrong offset can contact calipers or liners under load, not just at rest.
• Insufficient bolt engagement can strip threads. Count full turns on M14x1.5 during test fit.
• Brake package clearance varies by trim. Large calipers may limit spoke designs.
• Low load index or mis-sized tires risk heat buildup and ABS or speedo errors.
• TPMS compatibility and valve hardware can vary. Reuse or program sensors as required for your car.

Next steps

Checklist

• Identify your current wheel specs on the inboard barrel and tire sidewall.
• Open the calculator - set Installed on to 2014 Audi A7 with the OEM baseline above.
• Enter the donor wheel and tire sizes. Watch inner clearance and outer poke changes.
• Keep overall tire diameter near the OEM 255/40R19 outcome to maintain speedometer accuracy.
• Verify hub bore 66.6 mm. Plan hub-centric rings if donor bore is larger.
• Confirm brake caliper clearance with a test fit. Spin by hand and check lock-to-lock.
• Torque in a star pattern with a calibrated wrench. Recheck after 50-100 miles.

Gotchas

• Small hub bore will not go on the hub. Do not force fit.
• Spacer use changes effective offset and bolt engagement. Measure thread grip carefully.
• Seat type mismatch on lug bolts can loosen. Verify ball vs cone seats match your wheels.
• Not all 5x112 wheels clear A7 brakes. Spoke shape matters as much as diameter.

Tools and supplies

• Torque wrench
• 66.6 mm hub-centric rings
• M14x1.5 lug bolts
• Tire tread depth gauge

How to confirm on the calculator

Use Wheels from to select the donor vehicle or enter a custom wheel size. Set Installed on to 2014 Audi A7. Adjust Custom wheel size and Custom tire size. Check these outputs:

• Inner clearance change - keep safe gap to strut, liners, and arms.
• Outer poke change - avoid fender contact through full suspension travel.
• Tire diameter difference - aim close to OEM to keep drivability intact.

If any value is unknown or varies by trim, stop and confirm with your VIN at an Audi dealer or trusted OEM source. Then rerun the comparison.
