2017 Audi S5 Wheel Interchange

Goal

Find wheels from other vehicles that safely fit a 2017 Audi S5, under real-world constraints. The problem usually starts with a matching bolt pattern, then runs into offset, hub bore, brake clearance, and tire diameter. This guide walks you from uncertainty to a validated fit using the on-page calculator.

Prerequisites

What we know about the 2017 Audi S5 (mounting fundamentals)

• Bolt pattern: 5x112
• Center bore: 66.6 mm
• Thread size: M14 x 1.5

What is listed for OEM wheel and tire packages

Factory equipment varied by trim and package. The values below are provided, but they appear to come from different OEM packages. Do not assume both apply to your car at the same time.

Assumption: your car may have 18, 19, or 20 inch OEM packages depending on market and equipment. Validation is required.

How to confirm your baseline

• Check the driver door placard for tire size and load index.
• Look on the back of your wheel for size and offset stamps.
• Use the calculator on this page and select 2017 Audi S5 as “Installed on,” then verify the shown size against your placard and wheel stamps.
• Cross-check with your owner’s manual or dealer if anything conflicts.

Recommended tools

• Torque wrench for safe tightening: Amazon search
• Wheel hanger guide pin, M14 x 1.5: Amazon search
• Hub-centric rings for larger-bore donor wheels to 66.6 mm: Amazon search

Step by step

1) Set a known-good baseline in the calculator

• In “Installed on (your vehicle),” select 2017 Audi S5.
• Confirm the wheel and tire shown match your door placard and wheel stamps.
• If your placard shows a different size, adjust the “Custom tire size” and “Custom wheel size” fields to reflect your actual baseline. This ensures accurate comparisons.

2) Load the donor wheel or your proposed size

• If you have a donor vehicle, choose it in “Wheels from (donor vehicle).”
• If you have specs only, enter them in “Custom wheel size” and “Custom tire size.”
• Changing rim diameter updates overall tire diameter in the comparison view.

3) Compare the critical positions

• Inner clearance: The calculator shows how much closer the inner barrel moves to struts and liners. Less clearance increases rub risk on bumps.
• Outer poke: The calculator shows how far the outer lip moves toward the fender. More poke can cause fender contact on compression or steering.
• Offset trade-off: Higher ET moves the wheel inward. Lower ET moves it outward. Width changes shift both inner and outer edges.

4) Check hub and fastener compatibility

• Center bore must seat on 66.6 mm. Larger-bore wheels can be made hub-centric with rings. Smaller-bore wheels will not fit.
• Bolt pattern must be 5x112. Do not slot or force fit other patterns.
• Thread is M14 x 1.5. Verify bolt length and seat style with the wheel manufacturer or OEM literature. Seat style varies by wheel design.

5) Account for spacers if needed

• Spacers effectively reduce offset by their thickness in mm. Enter that by subtracting from ET in the calculator to preview fit.
• If spacers are
