Hand operated brass universal tyre deflators - no need for tools or deflators to air down. Let's say you want to set your tyres to 18 psi before you hit the beach. Before leaving home, using a pressure gauge you air out to 18 psi, screw these on, undo the top cap enough that it just starts to let air out, then go back just enough that it stops and locks the setting into place. This "sets" them to 18 PSI. Next time you're at the beach all you have to do is screw them on and they air down to 18 psi for you, just throw all four on and deflate in minutes. Remove them and screw the air caps back on before driving. Simple, time saving, easy.
