2009 Acura RDX — Frequently Asked Questions
What is the bolt pattern for a 2009 Acura RDX?
The 2009 Acura RDX uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 64.1mm and the offset is 45mm.
What other years of Acura RDX have the same bolt pattern as the 2009?

How do I measure the bolt pattern on my 2009 Acura?
The 2009 RDX uses a 5x114.3 pattern. For 4, 6, or 8-lug wheels, measure center-to-center across opposite holes. For 5-lug, measure from the center of one hole to the back of the opposite hole.
How tight should I torque the lug nuts on a 2009 Acura RDX?
Refer to your owner's manual for exact specs, but always tighten the 12x1.5 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
Can I use spacers on my 2009 Acura RDX?
Yes, but ensure the wheel spacers match the 5x114.3 bolt pattern and 64.1mm center bore. Also verify that you have enough thread engagement for your 12x1.5 hardware.
Why is matching the 64.1mm center bore important for the 2009 RDX?
The 64.1mm center bore ensures the wheel is perfectly centered on the hub. If the wheel is lug-centric instead of hub-centric, you may experience steering wheel vibration at highway speeds.
Fitment Checklist Before You Buy Wheels

- Confirm bolt pattern carefully. 5x114.3 is often confused with other common 5-lug patterns.
- Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
