Expert Buying Guide for 2002 GMC Sonoma Regular Cab
For your 2002 GMC Sonoma Regular Cab, the bolt pattern is 5x120.65mm with a 70.3mm center bore. When selecting aftermarket wheels, ensure they have a center bore of at least 70.3mm or 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 the correct 12x1.5 thread pitch and a conical (60-degree) seat—never use ball-seat lug nuts. Improper lug nuts can cause wheel loosening. Re-torque after 50-100 miles of driving.
