Pressure Imaging System for Tire Tread Analysis

The TireScan™ VersaTek™ system is a series of devices from Tekscan that can measure and record tire footprint pressure patterns. The tire footprints are recorded statically or dynamically using the TireScan™ VersaTek™ system, and results are displayed in color, at a high resolution. Different sizes can be measured using modular ruggedized electronics and base plates that have been configured with relevant sensor models.

The system's easy-to-use graphic and image analysis software enables quantitative and qualitative analysis of tire footprints in specific applications.

Key features of the TireScan™ VersaTek™ systems include:

  • The ability to produce graphs and analyze data
  • Sensors that are durable and can be reused
  • A rapid testing process which requires no ink, paper or scanning
  • Flexible recording and playback or results
  • Production of customized reports - quick and easy for the user
  • Reliable and repeatable measurements
