Proper tire pressure is essential for vehicle safety, fuel efficiency, and tire longevity, but manual checking and inflating is often neglected. This paper presents the fabrication of an Automatic Tire Inflating System that monitors and regulates tire pressure without manual intervention. The system uses pressure sensors, an Arduino microcontroller, and a 12V DC air compressor to continuously detect tire air pressure and automatically activate inflation when pressure falls below the preset limit. An LCD display shows real-time pressure readings, while LED indicators and a buzzer provide alerts for under- inflation and over-inflation conditions. The system automatically deactivates the compressor when optimal pressure is reached. Testing demonstrates 0.5 PSI measurement accuracy, automatic inflation response within 3 seconds of pressure drop detection, and inflation rate of 2 PSI per minute, achieving the target pressure of 32 PSI within 5 minutes from a 22 PSI under- inflated condition. The system enhances vehicle safety, improves fuel efficiency by 35%, and extends tire life by up to 20%.
