2022 Audi S5 Wheel Interchange

Goal

You want confidence that replacement wheels and tires will safely fit your 2022 Audi S5. The problem is small changes in width or offset can cause rubbing, vibration, or hardware mismatch. We will anchor on the known OEM specs, then use the on-page calculator at wheelinterchange.com to validate changes under real constraints.

Prerequisites

Assumptions and safety first:

• Vehicle: 2022 Audi S5. Trims may vary. Some OEM sizes differ by package.
• Baseline specs below reflect one OEM configuration. If your trim differs, confirm with the door placard and OEM documentation before ordering.
• Use the on-page calculator to model every change before purchase or installation.
• Lift and support the car properly. Recheck torque after a short drive.

Helpful tools:

• Torque wrench for wheel fasteners: search torque wrench 1/2 inch drive
• Digital calipers to verify center bore and ring sizes: search digital calipers
• Hub-centric rings sized to your wheel bore and 66.5 mm hub: search hub centric rings 66.5
• Wheel hanger guide pin for M14 threads: search wheel hanger guide pin M14

Known OEM Fitment for 2022 Audi S5

Use these values as the starting point in the calculator. Other factory packages may differ in rim and tire size. Verify your exact build with the door placard and OEM sources.

Step by Step

1) Confirm your current OEM baseline

• Check the driver door placard for size and load index.
• If your car shows different sizes than above, set those as “Installed on (your vehicle)” to match your exact build.
• If uncertain, validate with the owner’s manual or dealer parts catalog. Do not assume across trims.

2) Open the wheelinterchange.com calculator

• Set “Installed on (your vehicle)” to 2022 Audi S5 and select your exact tire and wheel if listed.
• Note: changing rim diameter in the “Custom wheel size” will update the tire diameter in the comparison. Watch the diameter change and speedometer impact.

3) Compare donor wheels or build a custom setup

• To test factory wheels from another vehicle, pick it in “Wheels from (donor vehicle)”.
• To test aftermarket sizes, use “Custom wheel size” and “Custom tire size”. Adjust width, offset, and tire measurements stepwise.

4) Evaluate inner and outer clearance

• Inner side: check clearance to strut, spring, and brake lines. The calculator displays inner clearance change versus baseline.
• Outer side: check fender and liner. The calculator shows how far the wheel “pokes” outward versus stock.
• Trade-off: more width often needs lower offset to preserve inner clearance, but that increases outer poke. Balance both constraints.

5) Check tire diameter and speedometer change

• Keep overall diameter within a small variance to protect ABS, gearing, and ride height.
• Use the calculator’s diameter and speedometer difference readouts as your validation.

6) Verify hub, hardware, and seating

• Center bore: your hub is 66.5 mm. Aftermarket wheels with larger bores require 66.5 mm hub-centric rings sized to the wheel’s bore.
• Thread size: M14 x 1.5. Match fasteners to the wheel’s seat type. Seat style varies by wheel design, so confirm cone or ball seat with the wheel manufacturer.
• Fastener length: if using spacers or thick wheel pads, verify thread engagement. A safe rule is visible full thread engagement by specification; confirm with OEM documentation for your model.

7) Brake and caliper clearance

• Spoke design affects caliper clearance even when diameter matches. Use manufacturer brake clearance templates when available.
• As a physical check, test fit one front and one rear wheel before mounting tires if possible.

Validation

• Static: with the car on the ground, turn lock to lock. Check inner fender liners and brake hoses.
• Compression: load the suspension over a speed bump and driveway transition. Listen for contact.
• Torque: tighten in a star pattern to the OEM torque spec for your S5. The specific value can vary. Verify in the owner’s manual or service information, then use a calibrated torque wrench.
• Hub-centric check: confirm the wheel centers on the hub with no play before tightening.
• Road test: drive at city and highway speeds. Re-torque after the first heat cycle and again after 50–100 miles.

Troubleshooting

Rubbing on inner side

• Cause: offset too high or width too large for the strut clearance.
• Action: reduce width or choose a lower offset in the calculator. Validate inner clearance change and re-test.

Rubbing on outer fender

• Cause: offset too low or tire sidewall profile too tall.
• Action: increase offset or select a tire with appropriate section width/aspect ratio. Recheck diameter and poke in the calculator.

Vibration at speed

• Cause: non hub-centric fit or imbalance.
• Action: install correct 66.5 mm hub-centric rings and road-force balance the wheels. Verify no debris on hub face.

Fastener mismatch

• Cause: incorrect seat type or thread length after spacers.
• Action: match seat profile to wheel design and confirm M14 x 1.5 threads. Validate thread engagement visually and by spec.

ABS or speedometer error after changes

• Cause: overall tire diameter moved too far from baseline.
• Action: adjust tire aspect ratio or width to bring diameter back within acceptable variance shown by the calculator.

Wrap up

Wheel fitment on the 2022 Audi S5 is precise. Your baseline is 5x112, 66.5 mm center bore, M14 x 1.5 threads, and an OEM configuration of 18x8.5 ET29 with 245/40R18 tires for the setup shown here. Other trims may use different sizes, so confirm your exact build. Model every change in the wheelinterchange.com calculator, validate clearances and diameter, and then install with proper hub-centric support and verified torque. This process turns uncertainty into a safe, predictable result.
