Before getting these, I used the 2 inches Marathon ice, and liked them. However, with any snow beyond 2 inches, I tended to bog down. In comparison, the 45nrth are far more surefooted in deeper snow and ice. The price is more rolling resistance on dry roads. It is a compromise I'm willing to make as bike is my main mode of transportation
If you live in a city that gets freezing rain, or frozen roads, but not much snow, the Marathon ice is a better tire. These are more than what you need. If you have to ride in loose snow and ice, these are the best, unless you are going way fatter
