Some tips from Firestone:
Test your battery – Have it checked out, as your battery can lose power due to the drop in temperature. The last thing you want is to be stuck in freezing weather with a car that won’t start!
Check your tire pressure monthly – For every 10 degrees the temperature drops, your tires can lose about 1 pound per square inch (PSI) of pressure. Monitor your tire pressure more closely during the winter time.
Replace all-season tires with winter tires – Temperatures lower than 45 degrees cause your all-season tires to stiffen and lose traction, but the latest generations of winter tires remain flexible in freezing temperatures, improving traction and available grip.
Check your tire depth with the penny test to make sure you have enough tread to grip the road in ice and precipitation.
Keep your car washed – Keep the exterior washed and waxed to protect your vehicle from the elements as the seasons change.
