Installation Guide
Pre-Installation Checks
- Verify Compatibility: Confirm that the wheel's bolt pattern (12x139.7mm), diameter (18 inches), width (9 inches), and offset (18mm) match your vehicle's requirements.
- Inspect Components: Before mounting, carefully inspect the wheel for any shipping damage or manufacturing defects. Ensure all included hardware (if any) is present.
- Tire Selection: Choose tires that are compatible with an 18x9 inch rim and meet your vehicle's load and speed ratings.
Mounting and Balancing
It is highly recommended that tire mounting and balancing be performed by a professional tire technician using appropriate equipment. Improper mounting can damage the wheel or tire and compromise safety.
Vehicle Installation Steps
- Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and loosen the lug nuts on the wheel to be replaced.
- Lift Vehicle: Safely lift the vehicle using a jack and secure it with jack stands. Remove the lug nuts and the old wheel.
- Clean Hub Surface: Clean any rust, dirt, or debris from the vehicle's hub mounting surface to ensure proper seating of the new wheel.
- Install Wheel: Carefully place the Mayhem Warrior 8015 Wheel onto the hub, aligning the bolt holes.
- Hand-Tighten Lug Nuts: Install lug nuts by hand, ensuring they thread smoothly. Do not use power tools at this stage.
- Lower Vehicle: Partially lower the vehicle until the tire just touches the ground, preventing the wheel from rotating while tightening.
- Torque Lug Nuts: Using a torque wrench, tighten the lug nuts in a star pattern to the vehicle manufacturer's specified torque. Refer to your vehicle's owner's manual for exact specifications.
- Final Lowering: Fully lower the vehicle and remove the jack and jack stands.
- Re-Torque Check: After driving approximately 50-100 miles, re-check the lug nut torque to ensure they remain properly tightened.
