With the 3.0 you are many percentile better off than those of us with the 4.4. I wish now I had looked harder. As to use in winter, I put Hakapalittas on wife's car-just 255-80-17. It will go anywhere we point it, winter of 13-14 was the worst around for decades and it was super car. Only thing I wish is I could get a reliable car starter installed. My big fight now are oil leaks, but we don't allow the age to slow us down driving it on some desolate winter highways.
