2016 Audi S7 Wheel Fitment and Interchange Guide

tl;dr

The 2016 Audi S7 uses 5x112 bolt pattern, 66.6 mm hub bore, and M14 x 1.5 lug bolts. The known OEM baseline here is 19x8.5 ET32 with 255/40R19 tires. Use the on-page calculator to compare donor wheels or custom sizes. Keep bolt pattern exact, keep the center bore at least 66.6 mm (use hub-centric rings if the wheel bore is larger), and match bolt seat type to the wheel. Verify clearance around brakes, struts, and fenders before committing.

Recommendation

As a practitioner, I start with confirmed OEM baselines, then test deltas with the calculator. Follow this sequence:

• Confirm your car’s baseline: check your door jamb label and owner’s manual. Trim, market, or brake package can change clearances.
• Enter the OEM setup into “Installed on (your vehicle)” in the calculator.
• For “Wheels from (donor vehicle)” or “Custom wheel size,” input the candidate rim width, diameter, and offset. If you adjust rim diameter, the tool will update tire diameter in the comparison.
• Keep bolt pattern exactly 5x112. Do not adapt unless you fully understand spacer/adaptor implications.
• Center bore must be ≥ 66.6 mm. If the wheel bore is larger, add hub-centric rings sized wheel-bore to 66.6. If smaller, the wheel will not seat.
• Stick with M14 x 1.5 bolts. Match bolt seat type to the wheel manufacturer’s spec. Audi OE wheels typically differ from some aftermarket seats, so verify.
• Use the calculator’s inner clearance and outer “poke” to check strut, liner, and fender space. Leave working room for suspension travel and steering.
• Account for brake caliper size. Some S7 packages use larger calipers. Measure or test-fit before driving.
• If spacers are required for clearance, ensure hub-centric design and longer, correct-seat bolts for safe thread engagement.
• Confirm TPMS compatibility and have new tires road-force balanced after mounting.

Impact

What changes when you alter size:

• Offset: Lower ET pushes the wheel outward. More fender “poke” and potential liner contact at the arch. Higher ET pulls inward and can hit struts or control arms.
• Width: Wider rims move both inner and outer edges. The calculator will show inner clearance changes and outer position compared to stock.
• Diameter: Larger overall tire diameter can rub under compression and affect speedometer reading. Smaller diameter can reduce ground clearance and alter ride.
• Center bore and hub-centricity: Proper centering prevents vibration. Rings are required when wheel bore exceeds 66.6 mm.
• Tire profile: Lower aspect ratios sharpen steering but reduce impact compliance. Confirm load rating meets or exceeds OEM.

Risks

• Wrong bolt pattern or seat type: can’t center properly or may loosen under load.
• Incorrect center bore: larger without rings causes vibration, smaller will not fit.
• Offset too aggressive: outer rub on fenders or inner contact with suspension and brakes.
• Insufficient thread engagement: using spacers without longer bolts is unsafe.
• Brake caliper interference: spoke design and barrel profile matter. Always test-fit.
• Speedometer and ABS behavior: big tire diameter changes can affect readings.
• Overtightening or undertightening bolts: can warp rotors or loosen hardware. Always torque to OEM spec from the owner manual or service data.

Next actions

Use this checklist to move from idea to safe fitment:

• Baseline: enter the known S7 setup into the calculator and save a screenshot for reference.
• Candidate wheel: input width, diameter, and offset for each option. Review inner clearance and outer position deltas.
• Tires: set section width and aspect ratio to maintain reasonable overall diameter. The tool will update tire diameter for comparisons.
• Hardware: confirm 5x112, M14 x 1.5, and correct seat type. Verify hub bore is ≥ 66.6 mm or plan hub-centric rings.
• Brakes: measure caliper-to-spoke clearance and barrel depth. Test-fit one wheel on the front axle first.
• Final: install with clean hub faces, torque in a star pattern to the OEM spec, then re-torque after 50–100 miles.

Helpful tools:

• 1/2 inch torque wrench
• Wheel hanger guide pin M14x1.5
• Hub-centric rings to 66.6 mm
• Tread depth gauge

Known OEM fitment for 2016 Audi S7

Values may vary by trim or market. If your car differs, confirm using the calculator and OEM sources before purchase.

How to confirm unknowns

If any value differs on your vehicle, confirm with your owner’s manual, a dealer parts department using your VIN, and a physical test-fit. Use the on-page calculator to visualize differences versus your baseline and avoid clearance surprises.

Gotchas

• Mixing bolt seat types between wheels and bolts leads to loosening. Always match the seat profile.
• Thin spacers without hub-centric lips reduce centering and can add vibration.
• Not all 19 inch wheels clear S7 front brakes. Spoke shape and barrel design matter.
• Tire stretch or oversize fits can pass static checks but rub under load. Leave margin.

Final note: Use the calculator to compare “Wheels from (donor vehicle)” to “Installed on (your vehicle),” then adjust “Custom wheel size” and “Custom tire size” until you land on a safe, clean fit. This process keeps changes predictable and installation trouble-free.
