Expert Buying Guide for 2008 Chevrolet Cobalt
For the 2008 Chevrolet Cobalt, the bolt pattern is 4x100 with a center bore of 57.1mm. When selecting aftermarket wheels, ensure the center bore matches or use hub-centric rings to prevent vibrations. The offset is critical: stock is around 40mm; deviations affect handling and clearance. Avoid offsets below 35mm to prevent rubbing. Always use lug nuts with the correct thread pitch (12x1.50) and seat type (conical/60-degree). Never use ball-seat lug nuts on this vehicle. Re-torque after 50-100 miles. Verify wheel weight capacity exceeds vehicle requirements.
