So far drove about 1.5 thousand. Strong wind and ice hit immediately as they were installed. I changed my shoes in time, you won’t say anything) I traveled 500 km with a trailer. The last 250 km drove for almost 5 hours, the trailer was going sideways, but Out was going very confidently. Quieter nordman7 and very quieter nordman5. Four - wheel drive and track , a quiet ride none of this saved from the departure of spikes . 7-8 on the front, 4-5 on the back. Dubeet at -20 the further minus the more it loses its properties, that is, grip. I'm changing my rating to 3.5
