Expert Buying Guide for 2009 Audi A5
The 2009 Audi A5 uses a 5x112 bolt pattern with a 66.6mm center bore. Aftermarket wheels often have a larger bore, requiring hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 29mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify spoke clearance against brake calipers. Lug nuts are 14x1.5 with a ball seat (R13 ball radius). Using incorrect seat type (e.g., conical) can lead to wheel loosening. Re-torque after 50-100 miles. Wheels from 2008-2024 A5 models are direct fit.

Quick Tips & Safety Warnings
- ✅ Use hub-centric rings (66.6mm ID to aftermarket bore) to avoid steering wheel vibration.
- ✅ Stick to offset 29mm ±5mm; lower offset pushes wheels outward, risking fender rub.
- ✅ Re-torque lug nuts to 90 ft-lb after 50-100 miles; use ball-seat lug nuts only.
- ⚠️ Confirm bolt pattern carefully. 5x112 is often confused with other common 5-lug patterns.
- ⚠️ Torque lugs in a star pattern to 100 ft-lbs (135 Nm), then re-check torque after 50-100 km (30-60 miles).

The 2009 Audi A5 uses a 5x112 bolt pattern (also called lug pattern or PCD). The center bore is 66.6mm and the offset is 29mm.
What other years of Audi A5 have the same bolt pattern as the 2009?
The Audi A5 uses the 5x112 pattern from 2008 through 2024. Wheels from any of these model years are dimensionally compatible with the 2009, provided the offset and center bore also match.
What lug nut size does the 2009 Audi A5 use?
The 2009 Audi A5 uses B 14x1.50 lug nuts. Always verify the thread pitch and seat type (cone, ball, or flat) match your aftermarket wheels.
What does 29mm offset mean for the 2009 A5?
An offset of 29mm means the wheel's mounting surface is 29mm away from its centerline. Changing this value drastically can affect suspension geometry and wheel bearing wear on your Audi.
Why is matching the 66.6mm center bore important for the 2009 A5?
The 66.6mm 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.
Do 2009 Audi A5s use lug bolts or lug nuts?
The 2009 A5 requires B 14x1.50 hardware. Check your specific trim to ensure you use the correct conical or spherical seating.
