Tire Traction Tester (TTT)

The Dynatest Tire Traction Tester (TTT) measures the peak friction characteristics on paved surfaces and it is used for tire testing to evaluate the dry or self-wetted friction characteristics of tires.

The TTT consists of a fully instrumented tow vehicle and test trailer, that uses a Dynatest two-axis force transducer to provide vertical load and horizontal tractive force measurements. As a pavement measurement device, it meets all the requirements of ISO 23671 and 15222, for wet grip measurements of C1 and C2 tires, as well as standard ASTM-E274, and ASTM-F408.
