What is the center bore of a 2006 Subaru B9 Tribeca?
The factory center bore (hub bore) for the 2006 Subaru B9 Tribeca is 56.1mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
What is the PCD for a 2006 Subaru B9 Tribeca?

Why is matching the 56.1mm center bore important for the 2006 B9 Tribeca?
The 56.1mm 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 lug nut size does the 2006 Subaru B9 Tribeca use?

Fitment Checklist Before You Buy Wheels
- 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).
