Abstract
A tire pressure indicator is provided which has a screw-threaded socket for long term but removable association with a tire valve. The body of the indicator houses a movable operator member; actuator member; and resilient member located between the operator member and actuator member. The arrangement is such that the actuator member is held in a 'rest' position by the resilient means which is compressed when the actuator member is moved to a 'test' position. The degree of compression and resilience of the resilient means are arranged such that the air release pin of the tire valve is depressed only in the event of air pressure in the tire being inadequate to counter the force exerted thereon through the resilient means. The sound of the air escaping in the 'test' position is indicative of a low tire pressure.
