A tyre pressure sensing module (104) for fitting to a wheel (106) of a vehicle (100) comprising a pneumatic tyre, a driver indicator unit (102) and a TPMS comprising the two. The sensing module comprising: a pressure sensor (214) for sensing a pressureof a gas retained within the pneumatic tyre; an alert generator (216) configured to generate an alert signal based on the sensed pressure of the gas and one or more parameters; and a transmitter (202) configured to transmit the alert signal to the driver indicator unit fitted to the vehicle. The driver indicator unit comprising a receiver (304) configured to receive alert signals from a plurality of tyre pressure sensing modules; and a display (314) configured to display an indication to a driver of the vehicle that the alert signal has been received. The tyre parameter may be a tyre pressure parameter and the alert generator is configured to generate a pressure alert signal if the sensed pressure is greater than or less than the calibrated pressure by more than the pressure parameter.
