Tyre inspection apparatus 10, (41 Fig.2) and a method of inspecting a tyre 34 using a tyre inspection apparatus. The apparatus 10 comprising a pressure measurement device 18 for connection to a tyre valve 32 of the tyre to provide a first tyre pressure measurement. A computer 12 communicates with a tyre pressure sensor 36 of the tyre to provide a second tyre pressure measurement of the tyre 34, wherein the computer 12 displays the first and second measurements. The computer may compare first and second measurements and alert if they are substantially different. Connection to the tyre pressure sensor may be via a wireless transceiver or wired on-board diagnostic (OBD) to a tyre pressure monitoring system (TPMS). The apparatus may display a third pressure measurement received from the TPMS. The computer may compare the third and first or third and second tyre pressure measurements and alert if they differ substantially. Absence of communication with the tyre pressure sensor may trigger computer to take first pressure measurement only and display the result. The apparatus may have a tread depth measurement device 44 and measurements may be used to determine uneven tyre wear and causes such as incorrect steering alignment, suspension setup, or over/under tyre inflation.
