I'm not sure what your winter conditions are but I would consider getting the Scorpions in the 255/55-18 size. I don't know if the 19 in. you asked about would fit. Tire Rack has a reasonably priced tire/wheel package. I just got them and they look like they will do the job. Usually in snow conditons you are better off with a little narrower tire, the wider ones tend to float on top and not get a good grip.
