Continental working on TPMS that measures tread depth
Most of us know the ‘20p test’ but in the years to come we’ll be able to spend our loose change rather than use it to gauge tread depth. Continental says it intends to add an automatic tread depth reading feature to its eTis (electronic Tire Information System) and aims to make this available for fitment on new vehicle models by 2017. According to Continental, this new feature is made possible by “intelligent software” that deduces tread depth from gradual changes in tyre rolling characteristics. An in-tyre pressure sensor infers running characteristics from the variations in tyre deformation.
