Hey, with experience from the one of worst snowbelts
inside the snowbelt(Buffalo beats us), you don't need tracks, and considering your resources would be better off without them.** In my opinion**. I also think treads look cool however. Here's the dealio. We own a snowblower with heavily treaded wheels that have navigated the deepest snow with relative ease. They are a heavy tread (3/4" knobs) but they would be far easier to turn, cheaper to obtain, easier to implement, be capable of a higher rate of speed, and be easier to maintenance than a comparable tread system. And as it is, you said that the trails would be packed, so it shouldn't be a problem.
<< Similar to this. You can get lots of different treads, and their pretty cheap too, considering a track.
