For the best traction in severe snow and icy conditions, use reinforced tire chains. Even if you drive with snow or all weather tires, keep a set of chains in your trunk. Keep the tire pressure at the recommended level. When you are stuck, some slight deflating may help your traction by placing more tread on the surface road, however this will increase tire wear. If you do slightly deflate tire pressure for traction, re-inflate the tires to the recommended pressure as soon as possible. You can add extra weight in the trunk of a rear-wheel drive vehicle to help traction. If you add weight for traction, make sure the weight is stationary, otherwise the vehicle may be more prone to spin outs. Place the weight as close as possible to the drive wheels. Weight in the trunk of a front-wheel drive car is not necessary! Do not spin your tires, because this causes friction that turns snow into ice, which will causes your automobile to get stuck even further.
