I have the 255/55/19 Duratracs and took someone's advice on bumping up the tire pressure to help offset the squishy feeling. I run 44 psi at all 4 corners and it handles much better on road.
I haven't had much of a chance to test them out in a lot of snow yet but they do amazingly well in slush and ice. We are getting a blizzard here in Maine on Tuesday, with an estimated 18"-24" of snow so they will be a good test.
Same here. I run 45 on each corner and it definitely helps.
