Be kind to your battery. Be sure to turn off radio, lights, heater, and wiper blades. Don't do anything that will suddenly affect your speed. The Trick is Traction Lower tire pressure results in less traction. Keep them properly inflated - tires drop one pound of pressure for each 10 degree drop in temperature.
Traction is greatest just before the wheels spin.
Gentle pressure on the accelerator is the best method for retaining traction and avoiding skids. If your wheels begin to spin, let up on the accelerator until traction returns. Carry extra weight over the rear wheels. In a skid, shift the car to neutral to equalize traction on all four wheels. Steer in the direction you want the front of the car to travel.
