A tire inflator is a device used to pump air into vehicle tires, ensuring they are properly inflated. Maintaining the correct tire pressure is essential for safety, fuel efficiency, and tire longevity. Tire inflators can be powered by electricity, batteries, or a vehicle's power outlet, making them convenient for home use or on-the-go emergencies. Most tire inflators come with a pressure gauge to help users monitor the inflation level. They often include various nozzles for inflating other items, such as bicycles, sports balls, or air mattresses. Compact and portable, tire inflators are valuable tools for any vehicle owner.
