Tyrata’s approach to tire tread wear sensing began as exploratory research with carbon nanotubes (tiny cylinders of carbon atoms just one-billionth of a meter in diameter) in a lab at Duke University. Fueled by ongoing innovation, the technology has evolved into a diverse product suite. The company’s IntelliTread® products are built on patent-pending sensing technology with solid-state sensors that collect data from the tread of tires without physically modifying the tire. Each IntelliTread® product directly correlates a sensor measurement with a current tire tread depth state, without the need for a multiplicity of sensors and complex algorithms to estimate the tire health.
Key innovations of IntelliTread® products:
- Drive-Over System (DOS) uses array of solid-state sensors to wirelessly detect tread depth from tires as they pass over the speed bump-like unit
- Internal Tread Sensor (ITS) uses the attenuation of wireless signals applied from the tire’s inner liner to directly measure tread depth
- External Tread Reader (ETR) uses customized optics to capture high-resolution surface maps of tire tread in a single capture
