Bolt pattern specifications you should know
To guide wheel replacements and aftermarket choices, these are the core specifications to verify:
- Bolt pattern: 5 lugs on a 112 mm circle (5x112)
- Center bore: 66.6 mm
- General compatibility: common across many Audi/VW Group models; verify offset and caliper clearance for your specific wheels
Knowing these specs helps ensure proper seating, alignment, and clearance when selecting wheels or adapters for your vehicle.
How to verify on your vehicle
If you want to confirm the bolt pattern on your particular car, follow these steps:
- Check the door jamb or owner's manual sticker for wheel specifications, which typically list bolt pattern and center bore.
- Measure the bolt circle diameter: measure across opposite lug holes to confirm 112 mm.
- Measure the hub bore: ensure the wheel's center bore is 66.6 mm or use hub-centric rings if the bore is larger.
These checks help ensure a proper fit and avoid issues with wheel seating or clearance.
