Tires losing air over time is a frustrating and sometimes confusing issue for drivers. While a puncture is the most common reason for air loss, slow deflation can still occur even when there’s no visible damage. If you find yourself constantly refilling your tires without an obvious cause, something else may be at play. Understanding what causes slow tire deflation and knowing how to prevent it can help you avoid unnecessary wear, improve fuel efficiency, and keep your car safe on the road. Temperature Changes and Air Pressure Loss One of the most overlooked reasons for slow air loss in tires is temperature fluctuation. As the temperature drops, so does the air pressure inside the tire. Cold weather causes the air molecules inside the tire to contract, reducing pressure. This is why many drivers notice their tire pressure warning light coming on during colder months. Conversely, when temperatures rise, air expands, which can temporarily restore som ... read more
