Solution

1. Preparation

Tools Required: Tire pressure gauge, jack, jack stands, lug wrench, soapy water solution in a spray bottle.
Ensure the vehicle is parked on a flat surface and the engine is off.
Place wheel chocks behind the rear tires for safety.

2. Inspect and Repair Tires

Sub-steps:
1. Remove the wheel cover (if applicable) using the lug wrench.
2. Loosen the lug nuts slightly but do not remove them completely.
3. Jack up the vehicle and secure it with jack stands.
4. Remove the lug nuts and take off the affected tire.
5. Inspect the tire for punctures or cuts; repair any punctures using a tire plug kit if located in the tread area.
6. If there are sidewall issues or significant damage, replace the tire.
7. Check the rim for any damage. If bent, consider replacing or repairing the rim.

3. Check and Replace Valve Stems

Sub-steps:
1. Remove the valve cap and apply soapy water to check for leaks.
2. If air bubbles form, replace the valve stem.
3. To replace, deflate the tire completely, remove the old valve stem using a valve core tool, and insert a new one.

4. Reinstall Tire and Inflate

Sub-steps:
1. Mount the tire back onto the rim.
2. Hand-tighten the lug nuts before lowering the vehicle.
3. Lower the vehicle and tighten lug nuts to the manufacturer’s torque specifications (usually 75-80 lb-ft).
4. Inflate the tire to the recommended pressure.
