Well today was quite a scary drive. It was my first day driving my E300 in snow and it was the worst time managing a vehicle in the snow that I have ever experienced. It was only about 2.5 inches of snow. I put 120# of bagged sand in the trunk last week, however, it feels as though the weight does not provide any traction assistance. The ARS light on the dash sure blinked a lot this morning. Even at 20mph the rear kept on wanting to come around the front. Except for one front wheel drive car many years ago I have driven rear wheel drive so I am rather used to then in the snow, but my E300 in the snow is like nothing else I have ever driven.
My wife said that she is done driving the car until spring.

Should I get another set of rims for narrow tires?
More weight in the truck?
Any other thoughts....
Thanks.
