A tyre tread depth checking device for measuring the depth of tread across a tyre on a wheel of a vehicle. The device having a measuring head including a profile gauge, a holding mechanism with movement means to push the gauge against the tyre to create a contoured profile on the gauge by contact with the tyre tread, a handling support to locate the gauge at the tyre while allowing a user to remain standing in use and recording means to record the measured depth of tread as shown by the contoured profile on the gauge. Embodiments are described in which the movement means is by a wheeled sub-frame and by air pressure from a bladder operated by a user. The recording means is by a sheet on which a permanent record of the contoured profile can be made as evidence of the tread depth.
