I am in one of the snowiest parts of the country, northeast Ohio, and I plan on driving my HCHII all year. (if its really bad, I do have a 4x4 I can use)

I bought the Goodyear Tripletred which are supposed to be great on snow and ice. I have them inflated to 40PSI. I might lower it a little in the winter for better traction.

So far I get around 54MPG in the summer, so these tires don't seem to affect mileage. I'm sure with LRR tires I could get more, but its a small trade-off.
