Is March Too Early to Winterize Your Car? Here’s What the Experts Say

Experts agree that in areas that see winter weather, proper winterization is one of the best ways to avoid winter vehicle problems. It is very difficult to get them to agree on the exact time to park your car in the winter because of the changing weather conditions across the country and from year to year. However, with the end of winter coming in March, it’s a good time to hibernate in much of North America.

Eric Auto, a used car specialist and new tire consultant in Quebec, Canada, advises its customers that changing winter tires can be done as early as March 16. However, since unpredictable winter weather often occurs in April, it is better to wait a few weeks to be safe.

Ultimately, expert recommendations for the exact time to dewinterize your car depend on your location and your current travel plans. For example, residents of many Rocky Mountain towns report March as their snowiest month. Even regions not known for significant amounts of snow can see heavy snow in March. National Weather Service data shows half of the top ten snowstorms in Oklahoma from 1951 to 2001 occurred in March.

If you live in one of the warmer states of the United States, you may not even need to winterize your car. Otherwise, removing winter in March, especially before the first day of spring on March 20, 2026, is a gamble in the middle of the country and probably a bad idea in any of the northern states.

The exact list of steps to de-winterize your car will depend on the winterization process you have followed in the past months. If you haven’t done anything special, such as installing snow tires or switching to high-visibility engine oil, your list will include only a few simple maintenance items.

One item on your de-winterization checklist should be washing your car thoroughly. Before the onset of winter weather, many city roads and interstate highways implement measures to prevent rain from freezing the roads, as a precaution. These methods can include road salt, which can cause serious damage to your car if you leave it in your car. Removing road salt and winter grime from your car is accomplished by thoroughly washing the undercarriage, as well as the entire exterior. It is also a good idea to sweep the carpets to remove traces of your feet throughout the winter.

Another item on the de-winterization checklist includes checking the air pressure in your tires. In the early days of winter you may want to add air to your tires to cope with changes in tire pressure due to cold temperatures. Now that the weather is warming up, it’s a good idea to make sure your tires aren’t overinflated, a condition that can cause excessive tire wear.

Your washer and dryer systems could use some love, too. Spring thaw and rain can cause havoc on the windshield if the wipers are not in top condition or the washer fluid reservoir is empty. Snow and ice can damage your wiper blades, rendering them useless, and even if you haven’t used any washer fluid, the reservoir can crack, leaving your windshield dry when you need a quick wash.
