The Ultimate Guide to Winterizing Your Vehicle in South Dakota

If you’ve spent even one winter in South Dakota, you know the cold here is no joke. Freezing temps, icy roads, and heavy snowfall can do a number on your vehicle. That’s why winterizing your car before the cold really sets in isn’t just a good idea—it’s a necessity.

Start with your battery. Cold weather can dramatically reduce battery efficiency, and older batteries are more likely to fail. Get it tested at your local auto parts store, and replace it if it's nearing the end of its lifespan. While you’re at it, check the terminals for corrosion and clean them with a wire brush if needed.

Next up: your tires. Winter tires provide better traction in icy and snowy conditions than all-season tires. If you don’t switch to dedicated snow tires, make sure your existing ones have plenty of tread—at least 6/32" is recommended. Also check your tire pressure regularly, as cold air causes pressure to drop.

Windshield wipers and washer fluid are another priority. Swap in a set of winter wipers, which are designed to handle snow and ice buildup. Fill your washer reservoir with a fluid rated for freezing temperatures. Visibility during a blizzard can be the difference between a safe trip and a serious accident.

Don’t forget your fluids. Make sure your coolant mix is winter-ready (usually a 50/50 antifreeze-to-water ratio), and that your oil is rated for cold starts. Some car owners switch to a thinner oil in winter, but always check your owner’s manual first.

Lastly, pack a winter emergency kit. Include items like blankets, jumper cables, a flashlight, ice scraper, shovel, sand or kitty litter (for traction), and non-perishable snacks. It’s not paranoia—it’s preparation.

Winter in South Dakota is tough, but with a little planning and some basic maintenance, your car can handle it like a champ.
