I would assume from your location that icy roads would frequently be a factor, so recommend studs of some sort. Also assume you are riding your Trek - if it has disc brakes, you could try "zip ties" around the rims & tires - check Youtube. The idea is similar to "winter tire chains" . I haven't personally tried this, but several local MTB enthusiasts use them on trails.
