TireScan™ System

tire pressure measurement system

Complete pressure imaging system for conducting tire tread analysis.

Tire Footprint Pressure Measurement

The TireScan^TM system is a unique tool used throughout the tire industry to capture static or dynamic tire footprint pressure patterns of passenger, truck, off road, agricultural, and aircraft tires. Various industry leaders such as Goodyear, Michelin, Bridgestone, and Pirelli use the TireScan pressure measurement system to analyze tread designs and conduct quality control experiments.

Because of its USB connectivity, TireScan can be used with equal ease in the lab, the factory, or in the field. Sensors can be placed directly on a roadway, a garage floor, mounted on a tire-rolling machine, or secured to a moving plank test machine. Sensors can even be buried underground and simply driven over to take a measurement within the soil.
