Inflate or deflate tires to the recommended pressure listed in the owner’s manual.
Recheck tire pressure after adjustments.

3. Tire Inspection and Replacement

Visually inspect each tire for damage or uneven wear.
If any tire is damaged or excessively worn, replace it with a new tire of the same specifications.
Parts Required: New tires (if necessary).

4. Wheel Balancing

Remove the wheel and tire assembly from the vehicle.
Mount the wheel on a wheel balancer.
Add weights as needed to balance the wheel.
Reinstall the wheel, ensuring the lug nuts are tightened to the specified torque.

5. Wheel Alignment
