I usually put sand bags in my trunk as well. With good tires and a little extra weight the Catera is manageable in snow. Also, donít use salt bags for weight (Iíve heard of many people doing this). Salt is caustic; if any spills in your trunk things will rust. The sand can also be used to help aid traction if you do get stuck. Pour some on the ground in front of your tires to help aid with traction.
