I was just coming to post about this... you are right... VERY bad on snow.

Not sure how it compares to a regular Civic but I'd never heard anything bad about them in the snow.

I moved the pressure down to 30psi, still bad.

7 - 600-mile tanks... farthest on "normal" gas fill= 643miles

And ONE 735-miler!! (cheated, over-filled tank )
