What is the Acura bolt pattern?
Most modern Acura passenger cars and SUVs use a 5-lug bolt pattern on a 114.3 mm bolt circle (5x114.3). However, there are exceptions by model and year, so check your specific vehicle to be sure.
What the bolt pattern means
The bolt pattern describes how many lug holes your wheel uses and the diameter of the circle that passes through the centers of those holes. It matters for wheel fitment, hub alignment, and brake clearance, and it must match your car’s hub and mounting system.
Common Acura bolt-pattern characteristics
Below is a concise picture of what you’ll typically encounter on Acura models sold in recent years.
- Five lug holes (a 5-lug pattern).
- Common bolt-circle diameter is 114.3 mm (4.5 inches) for most modern Acuras.
- Some older or specialty models may differ; always confirm with official specs for your exact vehicle.
In practice, the 5x114.3 pattern covers the bulk of current Acura lineups, including the TLX, RDX, MDX, ILX, and NSX families. Always verify for any exceptions related to your year and trim.
How to verify the bolt pattern for your Acura
To avoid wheel-fit issues, confirm the exact bolt pattern using primary sources and measurements. Here are reliable steps you can take:
- Check the owner's manual, doorjamb sticker, or the wheel specification sheet in the vehicle’s documentation for the exact bolt pattern.
- Look up your model and year on the manufacturer’s site or a trusted parts retailer to confirm the wheel specs.
- Measure the bolt circle yourself if needed: the distance between two opposite lug holes passing through the center equals the bolt-circle diameter.
- Compare with a reputable wheel catalog or consult a dealership or tire shop if you’re planning a wheel upgrade.
Having the correct specification helps ensure proper fitment, hub alignment, and safe operation.
Additional considerations for wheel choices
- Hub bore: ensure the wheel's center bore fits or use hub-centric rings if needed.
- Offset (ET): choose a compatible range to avoid rubbing or misalignment.
- Brake caliper clearance: ensure your wheels clear the calipers and rotors.
When in doubt, consult professionals or refer to the car’s service literature to avoid issues during installation.
Summary
In short, the typical Acura bolt pattern is a 5-lug setup on a 114.3 mm bolt circle (5x114.3). However, patterns can vary by model and year, so always verify the exact spec for your vehicle before purchasing wheels or adapters. With the correct data, you can ensure proper fitment, performance, and safety.
