Slime Tire Pressure Measuring Valve Caps are designed to give drivers an early warning when their tire pressure drops below the recommended pressure. When the pressure in your tire is normal, a green ring is visible around the top of the cap.
As the pressure begins to fall, the green ring becomes smaller. If no green ring is visible, your tire pressure should be checked immediately. Tire valve caps are set for 32 psi. Package contains 4 tire valve caps.
