The bolt pattern on a 2010 Audi A4 is 5x112 mm.
In practical terms, this means there are five lug mounting points arranged around a circle with a diameter of 112 millimeters. The 2010 A4, part of the B8 generation (2008–2016), uses this 5-lug, 112-mm pattern, which also influences the wheel center bore and overall fitment when shopping for replacement wheels or aftermarket rims. The typical hub bore for this generation is 66.6 mm, which matters for proper centering and balance when mounting wheels.
Bolt pattern basics
The "5x112" designation describes two key dimensions: quantity of lugs (five) and the circle diameter that those lugs form (112 millimeters). This pattern is standard across many Audi models from the late 2000s and into the 2010s, and it also overlaps with several Volkswagen Group vehicles. This compatibility can be useful when sourcing wheels from compatible models, provided other fitment factors align.
Center bore and fitment considerations
The center bore (the hole in the wheel that fits over the hub) for most 2010 A4 wheels is 66.6 mm. Wheels with a larger center bore can be centered with rings to ensure proper alignment, while wheels with a smaller bore will not fit without modification. When selecting wheels, verify both the 5x112 bolt pattern and the 66.6 mm center bore, and confirm the wheel's offset and width to avoid rubbing or clearance issues.
Practical implications for wheel shopping
For owners or buyers, the 5x112 bolt pattern means that aftermarket wheels designed for Audi and many VW Group models from the same era will often fit, provided the center bore and offset are appropriate. Always check the wheel manufacturer’s specifications for compatibility with a 2010 A4 and consider consulting a professional installer to verify correct fitment, especially if you plan to run low-profile tires or larger wheel sizes.
Summary
The 2010 Audi A4 uses a 5x112 bolt pattern with a 66.6 mm center bore. This configuration is standard for the B8 generation and guides wheel compatibility, informing choices when replacing wheels or upgrading to aftermarket rims. Confirm both the bolt pattern and center bore, and verify offset and clearance for your specific vehicle configuration.
