Expert Buying Guide for 2006 Pontiac Montana SV6
For your 2006 Pontiac Montana SV6, the correct bolt pattern is 5x115 with a center bore of 70.3mm. Aftermarket wheels often have a larger center bore, so hub-centric rings are essential to prevent vibration and ensure proper load distribution. The factory offset is 45mm; staying within ±5mm is recommended to avoid rubbing or clearance issues. Always use lug nuts with the correct thread pitch (12x1.50) and seat type—either conical (60-degree) or ball seat, matching the wheel's design. Improper lug nuts can lead to wheel loosening. Re-torque after 50-100 miles of driving.
