Safety Information
Always prioritize safety when handling and installing automotive components. Improper installation can lead to serious injury or damage.

Setup and Installation
Pre-Installation Check
Before beginning installation, inspect the wheel for any shipping damage or manufacturing defects. Ensure all included components are present.
- Verify the wheel's bolt pattern (5x120) and offset (ET-23) match your vehicle's specifications.
- Confirm the center bore diameter (78.1mm) is compatible or that appropriate hub-centric rings are available.
- Ensure adequate clearance with brake calipers and suspension components.
Mounting Instructions
- Clean the wheel hub and mounting surface on the vehicle.
- Mount the tire onto the wheel using proper tire mounting equipment. Ensure the tire bead is fully seated.
- Balance the wheel and tire assembly.
- Carefully position the wheel onto the vehicle's hub, aligning the bolt holes.
- Install lug nuts by hand to prevent cross-threading.
- Using a torque wrench, tighten lug nuts to the vehicle manufacturer's specified torque settings in a star pattern. Do not use an impact wrench for final tightening.
- Lower the vehicle and re-check lug nut torque after 50-100 miles of driving.
