first full day of riding on the new tracks :
1. as Tim of Adair Argo told me, the tire guides are rough on the tire sidewalls, I will have to make them smoother where it was laser cut.
2. the maxxis snow tires are way too soft for regular tire guides. the 4snow tires are ok in the plastic argo tracks with LARGE tire guides but too soft for the steel tire guides.
here is a picture taken by Martwell :
