Well I learned "My something new" thing for the day now I can go back to bed!! :laughing: I have never heard or seen these! Sorry but no help here! :dance1:
After reviewing and reading in detail the video and advertisement, I seriously doubt that there would be any improvement. Utilizing the use of flat strips of rubber instead of conventional chains might even escalate the danger of working in snow and ice.

Of course I have never used them, but engineering is engineering and physics is physics. Some things work and some things don't.:tractor:
