Unless it was completely untouched ice pellets, I had huge troubles going in a straight line. The 2 in wie SMWs run slightly below minimum pressure give me very good traction on bare ice. But this ice pellets stuff was much harder to manage than 5-10cm of snow regarding being pushed around on the streets.
How was it on the much narrower tires you guys are riding?

Fun fact: riding with a heavily loaded single-wheel trailer seems to help staying upright, so far.
