Summary

In order to measure longitudinal winter tire performance on snow surfaces in an objective way, you have to deal with a double challenge: Testing tires on a deformable soil (snow sur-face) with a good repeatability and making sure that the surface characteristics stay as stable as possible.  
This challenge was met by a carefully designed experiment based on tire/snow surface inter-action research. The choice of test facility, testing device, test method were focused on the extraction of the difference in tire characteristics and not the track variations.
