Expert Buying Guide for 2015 INFINITI Q40
For your 2015 INFINITI Q40, the 5x114.3 bolt pattern is shared with many Nissan/Infiniti models, but the 66.1mm center bore is critical. Aftermarket wheels often have a larger bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibrations and ensure proper load transfer. The factory offset is around 40mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always verify offset with test fitment. Use only lug nuts with the correct thread pitch (12x1.25) and seat type (cone or ball) matching your wheels—mismatched seats can lead to wheel loosening. Re-torque after 50-100 miles of driving.

Quick Tips & Safety Warnings
- ✅ Re-torque lug nuts to 80-90 ft-lbs after 50-100 miles; never use impact wrenches for final tightening.
- ✅ If using aftermarket wheels, ensure hub-centric rings are installed to match the 66.1mm bore; plastic rings are acceptable for street use.
- ✅ Avoid spacers unless necessary; if used, ensure extended studs and proper offset to maintain scrub radius.
- ⚠️ 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).

2015 INFINITI Q40 — Frequently Asked Questions
What is the bolt pattern for a 2015 INFINITI Q40?
The 2015 INFINITI Q40 uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 66.1mm and the offset is 40mm.
What is the center bore of a 2015 INFINITI Q40?
The factory center bore (hub bore) for the 2015 INFINITI Q40 is 66.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Why is matching the 66.1mm center bore important for the 2015 Q40?
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.
What is the PCD for a 2015 INFINITI Q40?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 2015 Q40, the PCD is 5x114.3.
What is the factory wheel offset for a 2015 INFINITI Q40?
The OEM offset for the 2015 Q40 is typically around 40mm. Depending on wheel width, a deviation of ±5mm is usually acceptable, but verify suspension clearance.
Will wheels from another INFINITI fit my 2015 Q40?
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.
