I've gone to a 2.65 wide Big Ben for the Winter, I'm going to keep the 1.25 Kojaks on for as long as I can, then put 2.0 Big Bens back on the front. We don't get the snow and ice here that you get. Your front tires look pretty good, not sure about the back one, need to look it up. Need to do a bit of video and show you a proper trailer setup, for our trikes.😉 Stay safe out there.
