Expert Buying Guide for 2000 GMC Sonoma Extended Cab
For your 2000 GMC Sonoma Extended Cab, the bolt pattern is 5x120.65mm with a center bore of 70.3mm. When selecting aftermarket wheels, ensure they have a center bore of at least 70.3mm; if larger, use hub-centric rings to prevent vibration and ensure proper load distribution. The offset range is 0-13mm; staying within this range maintains suspension geometry and prevents rubbing. Always use lug nuts with 12x1.5 thread pitch and the correct seat type (conical/60-degree) for your wheels. Mismatched seats can cause wheel loosening. Re-torque lug nuts after 50-100 miles of driving.
