Since the discovery of tires, improvement is being made on a vehicle's tires on a regular basis for its improved life and its role in increasing vehicle safety. As we all know that the vehicle is the most important part of our life because it helps us travel thousands in a few minutes. The air pressure of the tires must be maintained at an optimum level for a better functioning of the vehicle and for its safety. So this system was introduced taking into account fuel consumption, vehicle safety and comfort. It maintains the required tire pressure of the vehicle, increases fuel efficiency and reduces tire wear, thus increasing tire life and reducing tire replacement time and cost. The goal of introducing this system is to maintain the ideal tire pressure and when the tire pressure goes below the ideal pressure gauge it monitors it and the tire inflates again. This document provides a better understanding for researchers and new trainees on the operation, advantages and limitations of the "Automatic Tire Inflation System" used in a vehicle's tires.
