TMSI

What TMSI does

TMSI is a privately held US-based designer and manufacturer of specialized testing, measurement, and vision systems for the global tire and automotive industries. Founded in 1991 by Dr. Gerald Potts in Akron, Ohio (now headquartered in North Canton, Ohio), the company sells capital equipment and software to top-tier tire manufacturers — including Michelin, Bridgestone, Pirelli, Cooper, and Yokohama — automotive OEMs such as General Motors and Nissan, independent testing organizations like Smithers, and a long tail of motorcycle manufacturers, universities, and research laboratories.

TMSI's product portfolio spans four solution lines: force and moment testing (OnLEVEL force/moment machines, HSU-500 high-speed uniformity testers up to 250 km/h, rolling resistance testers, endurance systems, NVH machines, load/deflection testers), vision and measurement systems (DIC-3D non-contact full-field strain measurement, profile scanning, X-ray inspection, footprint testing), rubber processing and laboratory equipment (internal mixers, open mills, calenders, extruders, vulcanizing machines), and adjacent product lines covering tensile testing, environmental chambers, and gantry robotics. Its proprietary Dynamic Force Measurement System (US Patent No. 6,606,569; WO02/04906) eliminates equipment resonance to deliver zero phase lag from 0 to 500 Hz, and its DIC-3D vision technology enables non-contact full-field strain measurement that makes forces "visible" — capabilities the company describes as differentiated against traditional contact-based methods.

The business operates a sales-led, B2B hardware model with hardware sales as the primary revenue stream, supplemented by professional services (training, maintenance, repair, retrofits) and custom engineering. TMSI reaches global markets through a direct enterprise sales team, a wholly-owned subsidiary in Qingdao, China (established January 2019), service centers in Brazil, Europe, and India, and regional channel partners in Korea (Eins Global, April 2024) and Mexico (ASCI, October 2022). The company markets primarily through industry exhibitions (Tire Technology Expo, Automotive Testing Expo, RubberTech China) and technical society sponsorships, and has been accelerating investment in AI/data products since 2025 as a strategic vector beyond its core hardware franchise.
