Diagnostic Steps

1
Check the tire pressure using a digital or analog tire pressure gauge.
2
Inspect each tire visually for signs of damage, punctures, or foreign objects.
3
Verify that the valve stems are not leaking by applying soapy water and looking for bubbles.
4
Confirm that the tires are inflated to the manufacturer's recommended pressure (found on the driver’s door jamb).

Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is turned off.

2. Inflate Tires

Remove Valve Caps: Unscrew the valve caps from each tire.
Inflate Tires: Use an air compressor to inflate each tire to the recommended PSI (found on the driver’s door jamb).
- Tools Required: Air compressor or portable tire inflator.
- Safety Warning: Do not exceed the maximum PSI indicated on the tire sidewall.
Reinstall Valve Caps: Replace the valve caps securely after inflation.

3. Inspect for Leaks

Soapy Water Test: Mix soap and water in a spray bottle and apply it around the valve stems and any visible punctures.
Identify Leaks: Look for bubbles forming, which indicates air escaping.
Seal Minor Leaks: If minor leaks are found, consider using a tire sealant product as a temporary fix.

4. Repair or Replace Tires

Assess Damage: If punctures or significant damage are found, assess whether the tire can be repaired or must be replaced.
Repair Tire: If repairable, take the tire to a professional to patch it or use a tire plug kit if certified.
Replace Tire: If the tire is beyond repair, replace it with a new tire of the same size and specifications.
