TMSI's Tire Uniformity Test System provides the highest quality measurements available in tire uniformity testing for speeds up to 250km/h. The HSU-500 utilizes TMSI's patented Dynamic Force Measurement System US Patent No. 6,606,569 and International Patent No. WO02/04906 to assure a flat measurement band width with zero phase lag from 0 to 500 Hz. This is equivalent to standard test machine technology with a full machine resonant frequency of 5,000 Hz.
The system also provides Rolling Resistance tire measurement capability. The system is guaranteed to exceed the repeatability requirements of a reference system as defined in ISO 28580; and it includes automated test setups for the rolling resistance measurement standards ISO 18164, ISO 28580, SAE J1269 and SAE J2452.
