yes your MTs will not be so great on snow and ice, but there are a couple things you can do the help yourself out there, one have the center treat block sipped and you could restud them, but i dont like studs unless you drive on ice 99% of the time, on wet pavement they are bar far worse than a trailer tire. also the fact that you have a very narrow tire will help you in the now and ice as its a much smaller foot print still holding the same weight, so there for you have a much greater PSI to the ground than you would with a wider tire. your narrow MT tire i would venture to say will do just as good as a wide AT in hard packed snow and ice.
