3.1 TREADREADERTM HandHeld scanner
The TREADREADER™ HandHeld scanner is a compact and lightweight device. It is quick and easy
to use and eliminates errors associated with tread depth gauges.
The scanner is positioned on one edge of the tyre and operated by pushing it across the tread face. A
3D scan of each tyre constructed from up to 300,000 measurement points is used to calculate tread
depths with an accuracy of <0.2mm or 0.008”.
The 3D models of the tyre tread obtained using the TREADREADER™ HandHeld scanner can be
viewed, alongside the calculated tread depths, on a tablet.
A report containing vehicle identification, 3D tyre scans with colour-coded tread warning, and error
alarms for every axle and tyre position is available in TreadManager after scanning and syncing.
