Tire inflation refers to the process of filling a vehicle's tires with air to the recommended pressure. Properly inflated tires ensure better fuel efficiency, improved handling, and increased safety on the road. Each vehicle has a specific tire pressure, usually found on a sticker inside the driver's door or in the owner's manual. Maintaining the correct tire pressure is essential, as under-inflated tires can lead to faster wear and reduced traction, while over-inflated tires may cause a harsh ride and increased risk of blowouts. Regularly checking tire pressure with a tire pressure gauge can help ensure optimal performance and safety.
