In 2001, Smithers developed and patented a device to measure tire force and moment properties outdoors. Studies conducted using this vehicle resulted in the publication of SAE paper 2000-01-3431, Truck Force and Moment in Cornering - Braking - Driving on Ice, Snow and Dry Surfaces. 

ASTM F1805 / UN ECE R117 Snow Tire Traction

Smithers' small traction truck is ISO 17025 accredited for ASTM F1805 traction testing. The truck is used to test passenger and light truck (C1/C2) tires for the Rubber Manufacturers Association Severe Snow Use Symbol (3-peak mountain snowflake). It is also used for homologation of European winter tires UNECE R117.

UN ECE R117 / ISO 18106 C3 Snow Traction

Our traction truck can also evaluate C3 (truck and bus) tires for snow traction under the ISO 18106 standard. The standards measures snow traction of the candidate tire against a reference tire under a specified load.
