Real-time tire tread wear measurement Tyrata IntelliTread
Tire sensor and data management company Tyrata (Durham, NC) has announced that it has achieved a significant technology milestone in the development of its real-time tread wear sensors.

Mounted inside of the tire, the company's IntelliTread tire sensor technology uses wireless signals to track millimeter-scale changes in tread depth - a challenge given that tires are complex, heterogeneous structures composed of many raw materials with widely different properties. However, says the company, recent developments in sensor design and operation have produced repeatable results during tests in a variety of OEM passenger tires.

"With these recent results, Tyrata has demonstrated significant progress in moving from our early bench-top technology demonstrations towards real-world application of our sensors inside of a tire," says Jesko von Windheim, Chief Executive Officer of Tyrata. "By demonstrating reproducible measurements in various consumer tires, we've achieved a major milestone in the development of our technology.

"Our next goal is long-term, in-tire testing. We are starting to evaluate a host of tires for IntelliTread integration and invite collaborators to join us in this next phase of evaluation."

Through advances in sensor design and operation, along with electronics and packaging, the company says it has now successfully validated the technology in OEM passenger tires including steel belted radial tires from Hankook and Firestone. Sensors mounted to several sections from each tire produced predictable and repeatable responses when the tread was removed, one millimeter at a time.
