Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Safety tip: Allow tires to cool before measuring pressure to get accurate readings.

2. Inflate Tires

Sub-steps:
1. Use an air compressor to inflate each tire to the manufacturer's recommended pressure (typically found on the driver's side door jamb).
2. Recheck pressure with a gauge after inflation to confirm it meets specifications.

3. Check for Leaks

Sub-steps:
1. Mix soap and water in a spray bottle and apply it to the valve stem and tire bead.
2. Look for bubbles forming, indicating a leak.
3. If leaks are found, replace the valve stem or reseat the tire as necessary.

4. Install Tire Sealant (Optional)

Sub-steps:
1. If slow leaks are detected and cannot be repaired immediately, consider using a tire sealant product.
2. Follow the sealant manufacturer's instructions for application.

5. Monitor Tire Condition

Sub-steps:
1. Regularly inspect tires for signs of wear or damage.
2. Schedule a professional tire inspection if any issues persist.
