Given where you live, it depends on whether or not you plan to run seperate summer and winter tires. If you are going to has just one set of tires I would suggest the narrower tires. A wider tire will give you some flotation (not dig down as easy a narrow tire) help off road, but that same flotation can be a negative on snowy roads. A narrow tire will be better at digging down to the hard pack on snowy roads.
