The bolt pattern is a 5-lug configuration on a 112 mm circle (commonly written as 5x112).
In practical terms, there are five wheel studs arranged evenly around a circle that measures 112 millimeters in diameter. This specification is crucial for wheel compatibility, hub alignment, and overall safety. The 2010 Audi A5 shares this pattern with many other Audi models and some vehicles in the VW Group, though other dimensions such as the center bore can vary by wheel design.
Key specifications
Here are the core fitment numbers you need to know when checking wheels or replacements for the 2010 A5.
- Number of lug holes: 5
- Bolt circle diameter (BCD): 112 mm
- Center bore diameter: 66.6 mm
Knowing these specs helps determine wheel compatibility, hub requirements, and whether adapters or hub rings are necessary for a proper, centered fitment.
Practical implications for owners
What this means for wheel shopping and maintenance is straightforward: you should seek wheels that match the 5x112 pattern and, ideally, a 66.6 mm center bore to ensure proper centering. If a wheel’s center bore is larger, hub rings may be needed to eliminate any hub-centric gaps; if it’s smaller, the wheel won’t fit without modification.
- OEM and aftermarket wheels must match the 5x112 pattern with a 66.6 mm center bore, or use appropriate hub rings for centering.
- Some VW Group wheels are designed for 5x112 and will fit the A5, but always verify offset, brake rotor clearance, and lug hardware design before purchase.
- Using wheels with an incompatible offset or center bore can cause rubbing, alignment issues, or safety concerns—consult a professional if in doubt.
Always confirm the exact specifications with the wheel manufacturer and have a qualified technician confirm fitment and torque specs before installation.
Summary
The 2010 Audi A5 uses a 5x112 bolt pattern with a 66.6 mm center bore and a 112 mm bolt circle. This configuration is common across many Audi models and related VW Group vehicles, but always verify each wheel’s specific center bore, offset, and lug hardware to ensure a safe, proper fitment for your car.
