2021 Audi S4 — Frequently Asked Questions
What is the bolt pattern for a 2021 Audi S4?
The 2021 Audi S4 uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.5mm and the offset is 30-45mm.
What other years of Audi S4 have the same bolt pattern as the 2021?
The Audi S4 uses the 5x112 pattern from 1992 through 2024. Wheels from any of these model years are dimensionally compatible with the 2021, provided the offset and center bore also match.
Can I put aftermarket wheels on my 2021 Audi S4?
Absolutely. Just ensure the aftermarket wheels have a 5x112 bolt pattern, an offset near 30-45mm, and a center bore of at least 66.5mm (using hub rings if larger).
Why is matching the 66.5mm center bore important for the 2021 S4?
The 66.5mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.

Refer to your owner's manual for exact specs, but always tighten the 14x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
Fitment Checklist Before You Buy Wheels
