The bolt pattern on a 2008 Audi A6 is 5x112 mm (five lug holes arranged on a 112-millimeter circle).
For the 2008 A6, part of Audi's C6 generation, this pattern is the standard five-lug configuration used across most Audi models of that era. The pattern determines which wheels will bolt on directly and influences compatibility with aftermarket wheels, hub adapters, and center bore requirements. Here is a concise guide to what this means for wheel fitment and replacement options.
Bolt pattern basics
Why this matters for wheel fitment
Before listing the key facts you need to know about the bolt pattern on this model.
- Pattern: 5x112 mm (five lug holes arranged on a 112 mm circle).
- Center bore: 66.6 mm, which centers the wheel on the hub; wheels with a different bore may require hub-centric rings for proper alignment.
With these basics in mind, the fitment of wheels also depends on other factors like offset, width, and whether the wheel is factory OEM or aftermarket designed for 5x112. Always confirm all specs before purchasing or mounting wheels or tires.
Practical implications for wheel shopping
Here’s what buyers and restorers should consider beyond the bolt pattern to ensure a proper, safe fitment.
- Wheel diameter options commonly used on the 2008 A6 range from roughly 17 to 19 inches, depending on trim and package.
- Verify the wheel offset and width to maintain proper clearance for brakes, suspension, and fenders; mismatched offset can affect handling and tire wear.
- Make sure lug nuts match the lug nut size and seat type your wheels require; aftermarket wheels may use different seats, requiring adapters or different lug nuts.
Consult the owner’s manual or a dealership for exact OEM wheel specifications for your VIN, and test-fit with a professional if you’re mixing aftermarket parts.
Summary
The 2008 Audi A6 uses a 5x112 bolt pattern with a 66.6 mm center bore. This setup is common across Audi models from the mid-2000s, simplifying wheel compatibility within that family. Always verify full wheel specs (offset, width, bore, and lug nut details) against your specific vehicle, especially when replacing wheels or upgrading tires.
