Diagnostic Steps

1
Check the tire pressure of all four tires using a tire pressure gauge.
2
Inspect each tire visually for any signs of damage, such as cuts, bulges, or punctures.
3
Verify the recommended tire pressure from the vehicle's owner manual or the sticker located on the driver's side door jamb.
4
Check for any leaks around the valve stems and ensure they are not damaged.
5
Look for any obstructions or debris lodged in the tires that may cause low pressure.
