Tire monitoring system and its monitor receiver, monitor and sensor

A monitor receiver in a tire monitoring system comprising:

• sensors, each of which is provided for each of the tires equipped to a vehicle and detects conditions of the tire and wirelessly sends the detected result, and
• a monitor with said monitor receiver, which receives the detected result sent from each of said sensors, for monitoring conditions of said tires on the basis of said detected result received by the monitor receiver;
• wherein said monitor receiver comprises:
• a storage unit for storing more than two types of transmission method information for a data communication with said sensors;
• and
• switch means for selecting one type of transmission method information from said stored transmission method information and setting a data communication with a transmission method on the basis of the selected transmission method information available,
• wherein said transmission method information comprises data transfer bit rate information and transferred data format information.
