Tire pressure monitoring system

A tire pressure monitoring system comprising:

• at least one tire pressure gauge configured to be mounted on a valve-stem of a tire comprising:
• a radio frequency (RF) transmit/receive module for sending and receiving data indicative of a tire pressure wirelessly via a two-way wireless communication;
• a first processor;
• a first memory in communication with said first processor;
• and
• a pressure sensor configured for detecting a tire pressure of a tire and for transmitting a signal containing a value indicative of the detected tire pressure to said first processor;
• wherein said first processor is configured to store the value indicative of the detected tire pressure in said first memory and to instruct said first RF transmit/receive module to transmit a wireless signal containing data indicative of the tire pressure detected by said pressure sensor;
• and
• wherein said first processor is configured to instruct said first RF transmit/receive module to transmit a wireless signal only when the value of a tire pressure detected by said pressure sensor differs from a previous tire pressure value stored in said first memory by an amount exceeding a threshold value;
• a remote display unit comprising:
• a second RF transmit/receive module configured for two-way wireless communication with said first RF transmit/receive module;
• a second processor in communication with said second RF transmit/receive module;
• a second memory in communication with said second processor;
• and
• a display in communication with said second processor and configured to display data indicative of a tire pressure received from said first RF transmit/receive module, said display comprising:
• at least one first graphical element corresponding to a tire, said at least one graphical element configured to display data indicative of a tire pressure of said corresponding tire to a user;
• a second graphical element configured to display a plurality of pressure units for selection by a user, wherein selection of a pressure unit by a user causes said first processor to instruct said at least one first graphical element to display the tire pressure of the corresponding tire in the selected pressure unit;
• and
• at least one third graphical element corresponding to the tire, said at least one third graphical element comprising a graphical bar configured to render a color display corresponding to a tire pressure status of said corresponding tire to a user, said graphical bar including at least a first portion configured to generate a green display corresponding to the tire pressure status of the corresponding tire being within an acceptable range of a pre-set pressure threshold as determined by said first processor, and a second portion configured to generate a red display corresponding to the tire pressure status of the corresponding tire being outside of the acceptable range of the pre-set pressure threshold as determined by said first processor.
