2009 HUMMER H3T — Frequently Asked Questions
What is the bolt pattern for a 2009 HUMMER H3T?
The 2009 HUMMER H3T uses a 6x139.7 bolt pattern (also called lug pattern or PCD). The center bore is 100mm and the offset is 20mm.
What other years of HUMMER H3T have the same bolt pattern as the 2009?
The HUMMER H3T uses the 6x139.7 pattern from 2009 through 2010. Wheels from any of these model years are dimensionally compatible with the 2009, provided the offset and center bore also match.
Will wheels from another HUMMER fit my 2009 H3T?
Only if they share the exact same 6x139.7 bolt pattern, a compatible offset, and a center bore equal to or larger than 100mm.
Why is matching the 100mm center bore important for the 2009 H3T?
The 100mm 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 tight should I torque the lug nuts on a 2009 HUMMER H3T?
Refer to your owner's manual for exact specs, but always tighten the N 12x1.50 hardware in a star or crisscross pattern. Re-torque after the first 50 miles of driving.
What is the center bore of a 2009 HUMMER H3T?
The factory center bore (hub bore) for the 2009 HUMMER H3T is 100mm. If your aftermarket wheels have a larger hub bore, you will need hub-centric rings to prevent vibration.
Fitment Checklist Before You Buy Wheels
- Verify thread pitch before installation; M12x1.25 and M12x1.5 are not interchangeable.
- Torque lugs in a star pattern to 80 ft-lbs (108 Nm), then re-check torque after 50-100 km (30-60 miles).
