Next, inspect the tires for any visible damage, such as punctures, cuts, or bulges, and look for signs of uneven wear that may suggest an alignment problem. After this, examine each tire for potential leaks by visually inspecting them and listening for any hissing sounds; a mixture of soap and water can also help identify leaks by producing bubbles. Don’t forget to check the valve stems for any damage or air leaks, as faulty valve stems can lead to a loss of tire pressure. If the tire pressure warning light remains illuminated after addressing these issues, you may need to reset the tire pressure monitoring system, which can usually be done through the vehicle's onboard computer or by following the specific instructions in the owner's manual.
