Abstract
A tire low pressure audio warning device for monitoring a tire for low air pressure and sounding an alarm when a low tire pressure condition exists. The tire low pressure audio warning device has a body that attaches to a valve stem of an inner tube or tubeless tire, or to an opening through a rim of the tire. Contained within the body is at least a low air pressure switch, a battery and an audio alarm. The low pressure switch is in air communications with the pressurized air within the tire or the inner tube. The audio alarm is electrically connected to and activated by the low air pressure switch when a low tire pressure exits. A centrifugal switch is provided within the body to prevent the audio alarm from sounding during tire rotation. The centrifugal switch opens when the tire is rotating, and closes when tire rotation is stopped. The battery within the body provides electrical power for the alarm. The alarm is easily heard by a driver, or any one else, when walking past the tire, when the vehicle is stopped or parked. The low pressure setting can be factory set or it can be of an adjustable type. The monitoring device can be used on all tires inflated with air or other gasses.
