Solution

1. Preparation

Tools Required: Tire jack, lug wrench, tire repair kit (if repairing), tire inflator (if necessary), safety gloves, safety glasses.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and glasses for protection.

2. Loosen Lug Nuts

Using the lug wrench, slightly loosen the lug nuts on the flat tire while the tire is still on the ground, turning counterclockwise. Do not remove them completely yet.

3. Lift the Vehicle

Position the tire jack under the vehicle's designated jacking point near the flat tire.
Raise the vehicle until the tire is off the ground.

4. Remove the Flat Tire

Completely remove the loosened lug nuts and place them in a safe location.
Carefully remove the flat tire from the hub and set it aside.

5. Repair or Replace Tire

If repairing:
- Locate the puncture and use the tire repair kit to insert a plug according to the kit instructions.
- Ensure the patch is secure and allows for proper inflation.
If replacing:
- Align the new tire with the hub and slide it into place.

6. Reattach the Tire

Hand-tighten the lug nuts onto the wheel studs.
Lower the vehicle back to the ground using the jack.
Once the vehicle is on the ground, use the lug wrench to fully tighten the lug nuts in a star pattern to the manufacturer’s recommended torque (usually around 80-100 ft-lbs).

7. Inflate the Tire

Use a tire inflator to bring the tire pressure back to the recommended level (check owner's manual for specifications).
