Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Safety warning: Allow tires to cool before handling to avoid burns.

2. Tire Inspection

Remove any visible foreign objects from the tire tread.
If punctures are found, assess if they are repairable (less than 1/4 inch in diameter).

3. Tire Repair or Replacement

If Repairable:
1. Clean the puncture site and apply a tire plug or patch.
2. Use a tire repair kit to seal the puncture from the inside.
3. Inflate the tire to the recommended pressure.
If Not Repairable:
1. Remove the tire from the wheel using a tire iron.
2. Replace with a new tire of the same specifications.

4. Check and Replace Valve Stems

Remove the tire and inspect the valve stem.
If damaged, unscrew the old valve stem and replace it with a new one.
Reinstall the tire and ensure the new valve stem is sealed properly.

5. Reinstall and Inflate Tires

Reinstall all tires on the vehicle.
Inflate each tire to the manufacturer's recommended pressure (found in the owner’s manual or on the driver's door jamb).
Ensure all lug nuts are torqued to the manufacturer's specifications using a torque wrench.
