Multipurpose Tire Footprint Pressure Measurement

The TireScan™ CrossDrive system is a fully integrated solution capable of measuring large tire footprints at a high resolution. 250K sensing elements over a 508 mm x 508 mm (20 in. x 20 in.) area allows the system to measure footprints across a diverse tire portfolio (car to truck tires). The ruggedized housing is designed to handle harsh environments, allowing the system to collect footprint pressure data while the tire is experiencing shear forces from acceleration, deceleration, toe, and camber. The intuitive, application-specific graphing and image analysis software enables quantitative and qualitative analysis of the tire footprint.

Key Features:

• Dynamic recording and playback
• Graphing and data analysis capabilities
• Quick and easy generation of custom reports
• Durable & resuable sensors
• Thin & incompressible - dimensional stability is key for repeatable measurements
• Fast testing procedure. No ink, paper, or scanning

 

 

Key Applications Include:
Tire footprint pressure pattern evaluation Analyze various tire compounds and tread designs Assess suspension and camber Sipe and tread block design and testing	Tire mold adjustment Race vehicle "set-up" Manufacturing quality assurance Competitive benchmarking Road surface predictive wear studies

There have been a number of research projects conducted where Tekscan's pressure measurement technology has played a crucial role. To view the list of these research studies:
