Measure force and moment (F&M) properties that affect vehicle performance and handling by applying vertical, camber, steer, and drive/braking inputs to a spinning tire on a flat surface. The Flat-Trac family is the standard for tire F&M measurements and consists of several configurations to perform a wide range of steady state and dynamic testing to meet your testing needs.
Tire and automotive manufacturers worldwide rely on Flat-Trac technology to meet demands for higher performing tire designs
The Flat-Trac family can integrate into an Iterative mechanical Hardware-In-the-Loop (ImHIL) simulation environment to increase the speed of tire development while decreasing development costs
Local tire service expertise and life cycle management means a quick response with immediate troubleshooting ensuring system uptime
The complete Flat-Trac family comprises five standard configurations to meet a wide range of testing needs
