Start by verifying the tire pressure in all four tires using a reliable tire pressure gauge, ensuring that each tire is inflated to the recommended PSI as indicated in your owner's manual or on the sticker located inside the driver's side door jamb. Next, conduct a thorough visual inspection of each tire for any signs of damage, such as punctures, cuts, or bulges, which could lead to air loss. Additionally, check for leaks by examining the valve stems, tire bead, and tread area; a mixture of soap and water can help reveal leaks, as bubbles will form where air escapes.
