Winter Tire Safety

The Martha Stewart Show, December 2007

Do you know how much air is in your tires? Is it time for a replacement set? Follow these tips to ensure safe driving throughout winter.

1. Snow tires are made of materials that "hold" the road, and have deeper treads, which also give them better traction.

2. No matter which tires are on your car, make sure they are filled to the pound per square inch or "PSI" of air pressure that is recommended for your vehicle. This information is often found on the inside of one of the doors.

3. For every 10-degree drop in temperature, tires lose close to 1 pound per square inch of pressure, so check them often.

Winter Tire Trick
To ensure your tires have enough tread on them: Take a penny and hold Lincoln's body between your thumb and forefinger. Insert Lincoln's head into the lowest groove on the tread. If you can see above his head (where it says "in God we trust"), it's time for new tires.
