For most people, the short drive to work is by far their most polluting act of the day, especially winter cold starts. Cars are the single largest producers of carbon monoxide, nitrogen oxides and hydrocarbons. University of California researchers estimate that this ground level air pollution from cars causes up to 30,000 deaths per year in this country. Winter ice, snow and above all, salt will eat a high-performance machine alive. The wider and the knobbier the tire, the more traction you'll have on wet, icy or snowy roads.
Studded tires provide excellent traction on ice.
There is nothing more uncomfortable than a soaked, cold and gritty backside. Winter days are short, and you may find yourself riding in low-light conditions. Wisconsin law requires a front light and rear reflector after dark. A blinking red or amber rear light, reflectors and bright, reflective clothing are also vital to your safety. Dress in layers.
