Tires

Mount dedicated winter tires when temps consistently fall below 45°F — Bridgestone Blizzak and Michelin X-Ice are top performers
Confirm winter tire pressure weekly — cold air causes pressure to drop; inflate to the sticker spec on the door jamb
Inspect tread depth with a quarter — insert into a groove; if you can see the top of Washington's head, replace the tire

Load-test your battery at AutoZone or O'Reilly Auto Parts — free, takes 10 minutes, reveals true cold-cranking capacity
Replace batteries 4 years or older before winter — cold temperatures can cut cranking power by 35% and turn a weak battery into a dead one
Store a quality set of jumper cables (10-gauge, 20-foot) or a lithium jump starter pack (NOCO Boost Plus is compact and reliable)

Verify engine coolant is rated to at least -34°F — test with a $5 antifreeze hydrometer from any auto parts store
Change to a lower-viscosity oil if your owner's manual allows — 5W-30 flows better than 10W-30 in cold starts
Swap windshield washer fluid to a -20°F or -40°F rated formula — standard fluid freezes on your windshield at 32°F

Install winter wiper blades (Bosch Icon Winter or equivalent) — the rubber boot prevents snow from clogging the frame
Lift your wipers off the windshield before a predicted ice storm to prevent them from freezing to the glass

Pack an ice scraper with a brush on a 36-inch handle — short scrapers are useless on SUVs and trucks
Add a compact snow shovel, a bag of sand or cat litter (traction aid), and a wool blanket to your trunk
Include a high-visibility vest, road flares or LED triangles, and a waterproof flashlight
Keep a phone charging cable and a portable battery bank in the car — cold kills phone batteries fast
Pack calorie-dense snacks (granola bars, nuts) in case of extended breakdown in cold weather
