Diagnostic Steps

1
Visually inspect all tires for signs of punctures, cuts, or bulges.
2
Check the valve stems for cracks or damage.
3
Use a tire pressure gauge to measure the current tire pressure and compare it to manufacturer specifications.
4
Submerge the tire in water to check for air bubbles indicating a leak in the tire.
5
Inspect the wheel rims for corrosion or debris that may hinder a proper seal.
6
Verify that the tire beads are properly seated on the rims.

Solution

1. Preparation

Gather necessary tools: tire pressure gauge, soapy water solution, valve stem tool, and tire repair kit.
Ensure the vehicle is parked on a flat surface and the tires are cool before inspection.

2. Inspect and Repair Tire Damage

Sub-steps:
1. If punctures are found, use a tire repair kit to plug small holes according to manufacturer instructions.
2. If the tire is severely damaged (sidewall puncture or large cuts), replace the tire with a new one.
3. For minor leaks, apply the soapy water solution to the problematic area to locate bubbles indicating air escape.
4. If a valve stem is found to be damaged, remove it using a valve stem tool and replace it with a new valve stem.

3. Reseating Tire Beads

Sub-steps:
1. If the tire bead is not seated correctly, deflate the tire completely.
2. Use a bead seater tool to help reseat the tire bead where necessary.
3. Inflate the tire to the recommended pressure and check for leaks.

4. Final Inspection

Sub-steps:
1. After repairs, check each tire's pressure with a tire pressure gauge.
2. Ensure all tires are inflated to the specified PSI as per the vehicle owner's manual.
3. Check the tire pressure warning system to ensure it is functioning correctly.
