⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow tires to cool before performing any repairs or inspections.

Symptoms

•Frequent need to inflate tires
•Tire pressure warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect each tire visually for visible damage, punctures, or foreign objects embedded in the tread.
2
Check the valve stems for leaks using soapy water; bubbles will indicate a leak.
3
Measure tire pressure using a tire pressure gauge to assess if it is below the recommended PSI.
4
Perform a water submersion test on tires to check for small punctures that may not be visible.
5
Inspect the tire bead area for improper seating or corrosion that could cause air loss.

Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the tires are cool.
Tools Required: Tire pressure gauge, soapy water solution, tire repair kit, jack and jack stands, torque wrench.

2. Tire Inspection

Sub-steps:
1. Remove any visible debris or objects from the tire tread.
2. Use soapy water to coat the valve stem and check for bubbles indicating a leak.
3. If damage is found, proceed to repair or replace the tire as necessary.

3. Tire Repair/Replacement

Sub-steps:
1. If a puncture is found, clean the area around it and insert a plug from the tire repair kit.
2. If the tire needs replacement, loosen the lug nuts using a socket wrench, jack up the vehicle, and secure it with jack stands.
3. Remove the flat tire and replace it with a new or repaired tire, ensuring the bead is seated properly.
4. Reinstall lug nuts and tighten to the manufacturer’s specified torque (usually around 100-150 ft-lbs for F-150).

4. Tire Inflation

Sub-steps:
1. Inflate the tires to the recommended PSI as stated on the driver’s door jamb sticker.
2. Replace the valve stem caps to prevent dirt intrusion.
