Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety warning: Allow the vehicle to cool before working on tires.

2. Inflate Tires

Use an air compressor to inflate each tire to the manufacturer's specified PSI (usually found on the driver’s door jamb).
Re-check the pressure after inflation with a tire pressure gauge.

3. Inspect for Damage

Remove the tire from the vehicle using a jack and lug wrench if any damage is found.
Inspect the tire tread for punctures or wear, and check the sidewalls for bulges or cuts.

4. Repair or Replace

If a puncture is found, use a tire repair kit to patch the hole or replace the tire if the damage is severe.
If the valve stem is leaking, remove the tire and replace the valve stem.

5. Reinstall Tire

If the tire was removed, reinstall it on the wheel hub and torque the lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).
Ensure the tire bead is properly seated by checking for uniform gaps between the tire and rim.
