Solution

1. Preparation

Gather necessary tools: tire pressure gauge, soapy water solution, tire repair kit or replacement tires, wrench set, and jack.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Tire Inspection

Sub-step 1: Visually inspect each tire for punctures, cuts, or bulges. Mark any damaged areas.
Sub-step 2: Use a tire pressure gauge to check the pressure of each tire. Record the readings.

3. Leak Detection

Sub-step 1: Mix soapy water and apply it to the tire surface and around the valve stem.
Sub-step 2: Look for bubbles forming, which indicate air escaping. Note the location of any leaks.

4. Repair or Replace

Sub-step 1: If a puncture is found, remove the tire from the vehicle using a jack and wrench.
Sub-step 2: Follow the tire repair kit instructions to patch the tire or replace it if the damage is irreparable.
Sub-step 3: If the valve stem is damaged, replace it by unscrewing the old stem and installing a new one.

5. Reinstall and Inflate

Sub-step 1: Reinstall the tire onto the vehicle, tightening the lug nuts to the manufacturer's specified torque.
Sub-step 2: Inflate the tire to the recommended PSI as indicated on the driver's door jamb sticker.
