Tire Alert Pressure Cap is designed to give drivers an early warning when their tire pressure drops below the recommended pressure. If the tire pressure is too low, tire’s surface area touches the road and enhance the friction. This can lead to overheating, tread separation and even accident.It is an auxiliary tool for measuring tire pressure, locking tire pressure cap on top of the tire air nozzle, look directly at the color change in the transparent cover to judge the adequacy of the tire pressure.When the pressure in the tire is normal, a green ring is visible around the top of the cap. If no green ring is visible, the tire pressure should be checked immediately.
