Expert Buying Guide for 2020 Audi A4
For your 2020 Audi A4, the 5x112 bolt pattern is shared with all 1996–2024 A4 models, but critical dimensions must match. The center bore is 66.5mm; aftermarket wheels with a larger bore require hub-centric rings to prevent vibrations and ensure proper load transfer. Offset must stay within 30-45mm; deviations risk rubbing or poor handling. Always use lug nuts with the correct 14x1.5 thread pitch and proper seat type (ball or conical, depending on wheel). Mismatched lug nuts can cause wheel loosening or damage. Prioritize safety by verifying all specs before installation.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts after 50-100 miles of driving to ensure proper seating.
- ✅ Avoid using universal lug nuts; always match the seat type (ball for OEM Audi wheels, conical for many aftermarket wheels).
- ✅ Check for clearance between the wheel spokes and brake calipers, especially with aftermarket wheels, as the A4's brakes can be large.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ This fitment uses a wide offset range. Check brake clearance and fender clearance before buying wheels.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

2020 Audi A4 — Frequently Asked Questions
What is the bolt pattern for a 2020 Audi A4?
The 2020 Audi A4 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 A4 have the same bolt pattern as the 2020?
The Audi A4 uses the 5x112 pattern from 1996 through 2024. Wheels from any of these model years are dimensionally compatible with the 2020, provided the offset and center bore also match.
Can I use spacers on my 2020 Audi A4?
Yes, but ensure the wheel spacers match the 5x112 bolt pattern and 66.5mm center bore. Also verify that you have enough thread engagement for your 14x1.5 hardware.
Why is matching the 66.5mm center bore important for the 2020 A4?
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.
Will wheels from another Audi fit my 2020 A4?
Only if they share the exact same 5x112 bolt pattern, a compatible offset, and a center bore equal to or larger than 66.5mm.
What does 30-45mm offset mean for the 2020 A4?
An offset of 30-45mm means the wheel's mounting surface is 30-45mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Audi.
