2020 Audi S5 Wheel Fitment Guide
Think of this as a calm, step-by-step check. We will clear up the common mix-ups, show what actually matters, and help you use the on-page calculator without second guessing.
1) Misconception
Any 5x112 wheel should fit a 2020 Audi S5 if the diameter matches.
2) Why it seems true
Lots of VAG cars share 5x112. Many listings highlight only bolt pattern and diameter. Offset numbers look close across models, so it feels interchangeable.
3) What is true
Fitment is a system. Bolt pattern is just the start. The center bore, thread size, offset, width, and brake clearance all need to align with your S5. If one is off, you can get vibration, rubbing, or hardware that does not seat correctly.
Quick recap of the known OEM setup
This is a documented factory configuration for the 2020 Audi S5. Other factory options may exist by trim or package. If your car came with a different wheel or tire size, confirm it on your tire sidewall, the wheel’s inside spoke stamp, or the owner’s manual, then use the calculator on this page to compare.

Mental model: offset moves the wheel in or out, width spreads that movement on both sides, and the center bore keeps everything hub-centric. Your S5 wants a 66.5 mm hub-centric mount. If an aftermarket wheel has a larger center bore, use hub-centric rings to restore the 66.5 mm fit. If the bore is smaller than 66.5 mm, that wheel will not fit the hub.
For reference, 245/40R18 is about 653 mm in overall diameter, roughly 25.7 in. The on-page calculator uses this to keep your speedometer and fender clearance in check when you try different tire or wheel sizes.
4) Implications
Offset changes affect fender poke and inner clearance. Rule of thumb: each 1 mm of offset change moves the wheel 1 mm. Lower ET pushes the wheel outward. Higher ET pulls it inward.
Width changes affect both sides. Half the added width goes inward, half outward, before offset is considered. The calculator handles the math, but the mental model helps you sanity-check results.
Center bore must be 66.5 mm hub-centric on the car. If a wheel is larger, add rings sized wheel bore to 66.5 mm. Do not run loose on the hub.
Thread size is M14x1.5. Match hardware to the wheel’s seat type. Many OEM Audi wheels use a ball seat. Many aftermarket wheels use a conical seat. Use bolts that match the wheel seat the manufacturer specifies.
Spacer use is optional and case-by-case. If you add spacers, they change effective offset and require longer, correct-seat M14x1.5 bolts. Hub-centric spacers should match 66.5 mm to keep things smooth.
Brake clearance is not just diameter. Spoke design and offset matter. If in doubt, test fit a bare wheel and rotate to check the caliper area.
Tire diameter changes affect ride height and speedometer. Try to stay close to the 653 mm baseline unless you have reasons and clearance to deviate. The calculator shows the percentage change.
How to evaluate a new setup with the on-page calculator:
Set “Installed on” to 2020 Audi S5 using the known OEM 18x8.5 ET29 with 245/40R18.
Enter the donor wheel’s size or a custom size, including width and offset. If you change rim diameter, adjust the tire size so overall diameter stays within a comfortable range. The calculator updates tire diameter automatically to show differences.
Review inner clearance and outer poke changes, plus tire diameter and speedometer delta. Small changes are usually easiest to live with. Larger shifts need physical checks.
5) Quick tests
Confirm your baseline: read your tire sidewall and the size stamped on the inside of a wheel spoke. If it differs from the table, use your actual sizes in the calculator.
Hub fit check: the S5 hub is 66.5 mm. If your wheel bore is bigger, add rings that step it down to 66.5 mm. Search for hub-centric rings sized to your wheel bore to 66.5 mm.
Hardware match: verify M14x1.5 and the correct seat type for your wheels. Do not mix seat types.
Test fit with no tire rub: mount one front wheel and turn lock to lock. Then compress the suspension slightly or load the trunk to simulate bumps. Listen and look for contact.
Brake clearance: with the car safely supported, spin the wheel by hand and watch the caliper gap. You want clear daylight. If it is tight, consider a minimal spacer and matching longer bolts, then re-check the calculator for new offset.
Torque and re-check: torque to the Audi spec from the owner’s manual or service information. Re-torque after a short drive. If the spec is unknown for your trim, confirm with OEM service data or a dealer by VIN.
If any spec on your car differs from the table, that is fine. Use your actual numbers in the on-page calculator and verify against OEM sources like your owner’s manual, a dealer parts desk, or the stamping on your wheel. That mental model will keep things calm and predictable.
Methodology and sources
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
Bolt pattern / PCD
Center bore direction (donor wheel bore must not be smaller than the hub)
Wheel diameter, width, and offset against known OEM ranges
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.
