2019 Audi A7 Wheel Interchange

tl;dr

You can fit wheels safely on the 2019 Audi A7 by matching the hub, bolt pattern, and fastener thread, then using the on-page calculator to validate offset, width, and tire diameter. Known baseline values are below. Wheel and tire packages vary by trim and market. Confirm your exact OEM size on the door-jamb label, owner’s manual, or OEM parts catalog before buying.

The wheel and tire examples indicate multiple OEM packages. Your car may differ. Use the calculator with your real starting point.

Recommendation

I set up every Audi fitment the same way. Start with the hub, pattern, and fasteners, then tune diameter, width, and offset in the calculator before you order anything.

• Match the hub: choose 66.5 mm hub-centric wheels or use quality hub-centric rings sized to your new wheel bore and 66.5 mm at the hub.
• Match the pattern and thread: 5x112 and M14 x 1.5. Verify bolt or nut seat style against your wheels. Audi seat type can vary by wheel. Do not guess.
• Baseline your car: read your current tire size from the sidewall and the wheel size from the inner barrel casting. If unknown, confirm via the door-jamb label and OEM catalog.
• Use the calculator: set Installed on to 2019 Audi A7. Enter your current wheel and tire data. Compare candidate wheels by adjusting width and offset. Let the tool update tire diameter when you change rim diameter.
• Keep overall tire diameter close to stock to protect ABS and speedometer behavior. The calculator shows the delta. Aim small.
• Check clearances: inner strut and brake caliper, outer fender lip, and liner at full lock and compression. The calculator will show poke and inner clearance changes as you vary ET.
• Respect load rating: select wheels and tires that meet or exceed the A7 axle loads.

Impact

Each change has a predictable effect. Use these patterns to guide choices.

• Width up: more lateral grip potential. Increases outer poke and may reduce inner clearance. Ride can stiffen.
• Offset down: wheel moves outward. More fender poke, less inner clearance. Scrub radius increases.
• Offset up: wheel moves inward. More inner clearance risk for brakes and struts. Less poke.
• Diameter up: room for larger brakes and different tire options. Heavier if wheel choice is not optimized. Speedometer error if diameter changes.
• Unsprung mass: heavier assemblies hurt ride and braking feel. Lighter, strong wheels improve response.
• Center bore fit: true hub-centric mounting reduces vibration and rotor runout complaints.

Risks

• Rubbing: excessive width or low offset can strike the fender or liner on bumps or at steering lock.
• Brake interference: high offset or spoke design may contact calipers. Always test fit with the exact wheel.
• Vibration: incorrect center bore or poor quality rings cause steering shake. Use precise rings if the wheel bore is larger than 66.5 mm.
• Fastener mismatch: wrong seat type or thread length leads to loosening or hub damage. Verify M14 x 1.5 and seat profile against the wheel.
• Insufficient thread engagement: spacers or thick wheel pads can reduce engagement. Ensure safe engagement on every stud or bolt.
• TPMS compatibility: sensor type and frequency can vary by market and package. Confirm before mounting tires.
• Speedometer and ABS behavior: big tire diameter changes affect calibration and stability systems. Keep the delta small.

Next actions

Checklist

• Confirm your exact OEM sizes on the door-jamb label and owner’s manual. Note both wheel and tire sizes. The A7 had multiple packages.
• Open the calculator. Set Installed on to 2019 Audi A7. Enter your verified current sizes for a correct baseline.
• Enter a donor wheel or propose a Custom wheel size. Adjust rim width and offset until outer poke and inner clearance look safe on the visual and numbers.
• Let the calculator update tire diameter when you change rim diameter. Fine tune section width and aspect ratio to keep overall diameter close to baseline.
• Plan hardware: M14 x 1.5 fasteners with the correct seat for your wheel, and hub-centric rings if your wheel bore exceeds 66.5 mm.
• Test fit one corner. Spin the wheel by hand and check caliper and strut clearance. Cycle steering lock to lock.
• Mount and torque in a star pattern using the correct torque from the Audi manual. Re-torque after 50 to 100 miles.
• Book an alignment after significant size changes to protect tires.

Gotchas

• Do not rely on forum offsets. The A7 brake package and fender space vary by trim.
• Backspacing is tied to wheel width and offset together. If you widen the rim, adjust offset thoughtfully.
• Spacers require longer bolts and must be hub-centric. Verify with the calculator and a physical test.

Helpful tools

• 1/2 inch torque wrench
• Wheel hanger pin M14 x 1.5
• 66.5 mm hub-centric rings match inner size to your wheel bore
• Tire tread depth gauge

If a specification is missing or different on your trim, pause and confirm using the calculator, your VIN in the OEM catalog, or the owner’s manual. That small check prevents costly rework.
