Solution

1. Preparation

Ensure the vehicle is parked on a flat, level surface.
Gather necessary tools and equipment, including a jack, jack stands, and tire iron.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands to ensure safety.

3. Remove the Old Tires

Loosen the lug nuts using a tire iron, turning them counterclockwise.
Remove the lug nuts completely and set them aside.
Carefully remove the tire from the wheel hub.

4. Inspect and Replace

Inspect the wheel hub for any damage or debris.
Install the new tire onto the wheel hub, ensuring proper alignment.
Hand-tighten the lug nuts onto the wheel studs.

5. Lower the Vehicle

Use the jack to lower the vehicle back to the ground.
Once the vehicle is fully lowered, tighten the lug nuts in a star pattern to the manufacturer’s specified torque (typically around 80-100 ft-lbs).

6. Final Checks

Check the tire pressure of the new tires and inflate to the recommended PSI.
Dispose of the old tires properly according to local regulations.
