However, I have had both: a 325e and a 325is. The is rocked the world in the snow. About four or five years ago we had a montrous snow storm in State College PA and that 325is just pulled on through. I had Pirelli winters on it. They are awesome tires. However the 325e with its open diff sucked the big mongolian one. It was so light that it would just spin a rear tire and that would be the end of it. Scottie
