If this will be your first time driving in a winter climate, there are few things to consider. One of the most important things to remember is that how comfortable and competent you are driving in winter weather is important, but being aware of the other drivers around you is equally important. In other words, defensive driving techniques are valuable when driving in winter conditions and putting winter snow and ice tires on your vehicle is the best way to up your "defensive driver" status.
Most vehicles on the road today can be fit with winter / snow tires in either the Original Equipment sizes or "minus size." Tire and wheel packages will in nearly every case improve your snow and ice traction and decrease the overall cost of installation.
Search for winter tires or winter tires and wheel packages by vehicle.
Be safe and enjoy the ride.
