Expert Buying Guide for 2006 Subaru B9 Tribeca
For your 2006 Subaru B9 Tribeca, the 5x114.3 bolt pattern and 56.1mm center bore are critical. Aftermarket wheels often have a larger center bore (e.g., 73.1mm), requiring hub-centric rings to prevent vibration and ensure proper load transfer. The factory offset is 55mm; deviations beyond ±5mm may cause rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.25) and seat type—factory wheels use a ball seat, while many aftermarket wheels require a conical (60-degree) seat. Never mix seat types, as this can lead to loose wheels. Re-torque after 50-100 miles to maintain clamping force.

Quick Tips & Safety Warnings
- ✅ Use hub-centric rings with a 56.1mm inner diameter to match the vehicle's hub; plastic rings are acceptable for street use, but aluminum is preferred for track use.
- ✅ When selecting aftermarket wheels, verify that the wheel's hub bore is at least 56.1mm; if larger, rings are mandatory. Avoid wheels with a smaller bore.
- ✅ Always re-torque lug nuts to 80-90 ft-lbs after 50-100 miles of driving, as the wheel settles and clamping force can decrease.
- ⚠️ 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).

The 2006 Subaru B9 Tribeca uses a 5x114.3 bolt pattern (also called lug pattern or PCD). The center bore is 56.1mm and the offset is 55mm.
What other years of Subaru B9 Tribeca have the same bolt pattern as the 2006?
The Subaru B9 Tribeca uses the 5x114.3 pattern from 2006 through 2007. Wheels from any of these model years are dimensionally compatible with the 2006, provided the offset and center bore also match.
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?
PCD stands for Pitch Circle Diameter, which is the same as the bolt pattern. For the 2006 B9 Tribeca, the PCD is 5x114.3.
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?
The 2006 Subaru B9 Tribeca uses N 12x1.25 lug nuts. Always verify the thread pitch and seat type (cone, ball, or flat) match your aftermarket wheels.
