To get a good year round tire for your use, truly depends on what kind of country you live in. This board has people from all over Canada and the States and even some from Europe. Opinions and experience will vary widely.
Here winter can be 50 below to, summer 90 above F. We get a lot of snow and ice in winter and deep mud and dirt roads in the summer, along with pavement use. I have tried all kinds of tires, I run Duratracs, as does 90% of the oil patch up here. They have large lugs for mud and snow, the newer version has way more syping for ice and wet, but they are noisier due to the aggressive tread. They also have the 3 Peaks which we need if we run in B.C. during the winter.
If I lived in Sandy dry country, with wet pavement, ice, and little snow, my choice would be very different. There is no such thing as an AT tire that is as good as a pure winter. What you need to find, if you want to run one tire year round, is the right choice for your specific area. A quality local shop should be your best source of recommendations for your area.
