A vehicle wheel monitoring system (1200, Fig.12) comprising a sensor module 1400 for coupling to a vehicle wheel (1204) comprising a sensor (1414, Fig.14) configured to measure a wheel parameter 1706 in response to a request 1704, and a transmitter (1402) that transmits data indicative of the parameter to a signal repeater 1300 using a short-range telecommunication signal 1708 over a first distance. The signal repeater comprises a short range transmitter (1302, Fig.13) configured to transmit the request 1704 to the sensor module over the first distance; a receiver (1304) configured to receive the data from the sensor module 1710; and a further transmitter (1314) configured to transmit the data 1712 to a user device 1500 configured to receive said data using a telecommunications signal over a second distance greater than the first distance, for display of the parameter to a user 1716. Transmission of data from repeater to user device may be at substantially 2.45GHz. The system may further comprise a keyed recess (304, Fig.3a) to aid correct relative location of the sensor module and repeater. Also claimed is a vehicle wheel comprising the monitoring system, and a method of using the monitoring system.
