Smart speed bumps to automatically check tyre tread depth.

Drivers entering car parks could soon have their tyres automatically scanned for tread depth. After a Finnish company announced the expansion of its tyre-checking speed bumps.

Nokian’s SnapSkan system features a ‘smart’ ramp that can be installed in public car parks and similar locations. When driven over, the speed bump uses 3D scanning to measure the tread depth of all four tyres.

The system is free to use, and drivers wanting to make use of it can opt in via text message or email. Signing up either before or after they have driven over the ramp.
