ABSTRACT:
A tire air pressure monitoring system is provided with at least one trailer-use receiving unit, which is mounted at a rear end of a tractor head to receive radio wave sent by multiple tire air pressure sending units. The tire air pressure sending units are respectively attached to wheels of a trailer. The trailer-use receiving unit, having a directional antenna, is oriented to have a stronger receiving sensitivity with respect to a direction of the trailer than other directions.
