Expert Buying Guide for 2009 INFINITI EX
The 2009 INFINITI EX uses a 5x114.3 bolt pattern with a 66.1mm center bore. When installing aftermarket wheels, hub-centric rings are mandatory to match the bore precisely, preventing vibrations and ensuring proper load distribution. Offset is critical; the factory spec is around 40mm. Deviating more than ±5mm may cause rubbing or clearance issues with suspension and brakes. Always use lug nuts with the correct thread pitch (12x1.25) and seat type—factory wheels use a conical (60-degree) seat. Using incorrect lug nuts can lead to wheel loosening or damage. Safety first: verify all specs before installation.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80-90 ft-lbs after 50 miles of driving to ensure proper seating.
- ✅ Avoid using universal fit wheels without hub-centric rings; the 66.1mm bore is specific and requires rings for safe fitment.
- ✅ Check inner clearance for aftermarket wheels; the EX has limited space near the strut and brake caliper, especially with lower offsets.
- ⚠️ Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- ⚠️ 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).

2009 INFINITI EX — Frequently Asked Questions
What is the bolt pattern for a 2009 INFINITI EX?
The 2009 INFINITI EX uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 66.1mm and the offset is 40mm.
What other years of INFINITI EX have the same bolt pattern as the 2009?
The INFINITI EX uses the 5x114.3 pattern from 2008 through 2013. Wheels from any of these model years are dimensionally compatible with the 2009, provided the offset and center bore also match.
Can I put aftermarket wheels on my 2009 INFINITI EX?
Absolutely. Just ensure the aftermarket wheels have a 5x114.3 bolt pattern, an offset near 40mm, and a center bore of at least 66.1mm (using hub rings if larger).
Why is matching the 66.1mm center bore important for the 2009 EX?
The 66.1mm 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.
How do I measure the bolt pattern on my 2009 INFINITI?
The 2009 EX 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.
Will wheels from another INFINITI fit my 2009 EX?
Only if they share the exact same 5x114.3 bolt pattern, a compatible offset, and a center bore equal to or larger than 66.1mm.
