Solution

1. Preparation

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

2. Inspect and Repair Tires

Sub-steps:
1. Remove the tire from the vehicle using a jack and tire iron.
2. Inspect the tire thoroughly for punctures or foreign objects lodged in the tread.
3. If a puncture is found (less than 1/4 inch), use a tire repair kit to plug the hole or take it to a tire shop for professional repair.
4. For larger damage or sidewall issues, replace the tire with a new one.

3. Check Valve Stems

Sub-steps:
1. Inspect each valve stem for cracks or damage.
2. If damaged, remove the old valve stem using a valve stem tool.
3. Install a new valve stem, ensuring it is properly seated.
4. Reinflate the tire to the recommended pressure.

4. Reset TPMS (if applicable)

Sub-steps:
1. Ensure all tires are inflated to the correct pressure.
2. Locate the TPMS reset button (usually under the steering wheel).
3. Press and hold the button until the TPMS light blinks and then turns off.
4. Start the vehicle and verify the TPMS light is no longer illuminated.
