Solution

1. Preparation

Tools Required: Tire jack, lug wrench, tire pressure gauge, tire repair kit (if applicable), or new tire.
Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools and safety gear (gloves, safety glasses).

2. Remove the Flat Tire

Loosen the lug nuts slightly while the tire is still on the ground.
Use the tire jack to lift the vehicle until the tire is off the ground.
Fully remove the lug nuts and take off the flat tire.

3. Repair or Replace the Tire

If Repairing:
1. Clean the puncture site using a reamer tool from the tire repair kit.
2. Insert a rubber plug into the puncture using a plug insertion tool.
3. Trim excess plug material with a knife.
4. Inflate the tire to the recommended pressure.
If Replacing:
1. Remove the tire from the rim using a tire machine or take it to a professional.
2. Install the new tire on the rim, ensuring proper bead seating.
3. Inflate the new tire to the recommended pressure.

4. Reinstall the Tire

Align the tire with the wheel hub and place it onto the vehicle.
Hand-tighten the lug nuts onto the wheel studs.
Lower the vehicle back to the ground.
Tighten the lug nuts in a crisscross pattern to the manufacturer’s specified torque (typically around 76 ft-lbs for the Highlander).

5. Final Check

Recheck the tire pressure and ensure it is at the recommended PSI.
Store tools and dispose of any old tire materials properly.
