How Minnesota drivers can wipe their snow boogers this winter

It’s that time of year to ask: “Why is my car shaking when I accelerate?”

Winter is here, and it has brought snow gremlins.

Minnesota’s temperamental winter has added stress for drivers dealing with slick roadways, low tire pressure, gunked-up wheel wells and other issues that rise when temperatures drop.

Here’s a quick guide to winter vehicle maintenance for what is expected to be a snowier and colder than normal season:

Pick the ‘snow boogers’

Some call them “snow boogers” while others call them “snow gremlins,” but all Minnesotans recognize the dirty snow that builds up inside tire wells.

Danny Woods, store manager for Discount Tire in Maplewood, said cars often shake when accelerating after 4 to 10 inches of snow falls because snow packs into the wheel well and throws tires off-balance. To get rid of the problem, he said drivers should:

  • Pick the snow boogers with a shovel or stick. Manufacturers often leave space in tire wells where drivers can clean out the gunk.
    • Wash your car. Taking your vehicle through a car wash when it’s warm enough is a hands-free way to get rid of snow packed within tire wells.
      • Bring it to a professional. If all else fails, take your car to a mechanic or auto professional who can clear it for you.

        Check those tires

        As owner and mechanic for Tuan Auto Repair in St. Paul, Raks Pham stays busy fixing about 20 cars a day. Some drivers call or visit his shop to get rid of snow boogers, but Pham said most winter fixes center on heating, brakes and tires.

        Checking your suspension and aligning your tires “saves on wear of the tires to make it last as long as you can so you’re not spending $1,200 or $1,300 on new tires,” Pham said. “Tires will make a world of difference in snow and ice.”

        At Discount Tire, Woods knows that well. He said the Maplewood location is the busiest in Minnesota, averaging about 120 cars a day throughout the year. That daily average surges to 250 cars during winter, making it “the busiest store in the country,” Woods said.

        He said drivers can avoid hefty repair costs by switching to winter tires before snow falls.

        “It’s actually recommended to start putting [snow tires] on halfway through October,” Woods said. “Even on dry pavement, a winter tire in colder temperatures grips the road so much better and keeps them safe.”

        Wipe snow off the roof, too

        Lt. Mike Lee of the Minnesota State Patrol said the number of crashes increases during the winter, though incidents during the summer often involve higher speeds and are more violent.

        To avoid serious traffic incidents, Lee advised drivers to:

        • Check Minnesota 511 for road conditions and traffic updates before you travel.
          • Make sure your car’s in working order before driving. Is there enough tread depth in your tires? Do the blinkers and headlights work?
            • Brush snow off all parts of your vehicle, especially the roof. Lee said the snow that flies off your car can lower visibility for drivers behind you, and that snow can freeze into slick spots on the highway.
