- Install new tires, ensuring proper rotation direction if applicable.
- Tighten lug nuts to manufacturer torque specifications (typically around 100-120 ft-lbs).

3. Wheel Balancing

Balance the Wheels:
- Mount the wheel on a balancing machine.
- Add weights as recommended by the machine to achieve balance.
- Reinstall the balanced wheels onto the vehicle.
