The Importance of Preparing for Winter Driving
Winter is a harsh season for vehicles, not only in cold regions but also in urban areas where morning and evening chills, frozen road surfaces, and dead batteries are common. As temperatures drop, engine oil thickens and battery performance decreases. Additionally, without winter tires installed, the risk of slip accidents on snowy or frozen roads increases dramatically. The first step to safe driving is "preparing before winter arrives." It's recommended to complete inspections by late November to early December.
How to Choose Winter Tires and When to Replace Them
The most important aspect of winter preparation is winter tires. When temperatures drop below 45°F (7°C), summer tires harden and lose grip. Even without snow, low temperatures alone can create dangerous conditions, making early tire replacement crucial.
When selecting winter tires, check the following three points:
- Rubber softness: Softer rubber has better adhesion to ice surfaces and is less likely to slip.
- Tread pattern (groove shape): Affects water drainage and snow removal performance.
- Manufacturing date: Rubber deteriorates over time, so aim for tires manufactured within 3 years.
Recommended winter tires include:
- Bridgestone "BLIZZAK VRX3": High performance on ice and durability, versatile for urban areas.
- Yokohama "iceGUARD 7": Good fuel efficiency and excellent quietness.
- Dunlop "WINTER MAXX 03": Popular for cost performance.
The optimal timing for replacement is late November to early December when temperatures drop to single digits. If you've just purchased a used car, check the tire tread depth and manufacturing date early.
Battery Checks and Replacement Guidelines
Dead batteries are a particularly common winter problem. Voltage drops due to low temperatures, making engines harder to start. If your battery is more than 2 years old, have the voltage checked and replace it if necessary.
Recommended battery brands:
- Panasonic "Caos" series: High performance and long-lasting.
- GS YUASA "ECO.R Revolution": Features fuel efficiency improvement and compatible with idling stop vehicles.
- BOSCH "High-Tech series": Attractive stable output compatible with European cars.
Also, if you notice the engine is hard to start, keeping a jump starter (portable battery) in your car provides peace of mind.
Reviewing Engine Oil and Coolant
In cold weather, oil viscosity increases, making engine starting heavier. For winter, choose oil with excellent low-temperature fluidity (e.g., 0W-20 or 5W-30). Especially with used cars where you often can't know what type of oil the previous owner used, it's recommended to change it early after purchase.
Coolant (LLC) also has antifreeze functions, but performance decreases with deterioration. In sub-zero regions, use high-performance coolant like "-40°F compatible types." Popular products include WAKO'S "LLC Premium" and others.
Ensuring Visibility with Wipers and Washer Fluid
On snowy or sleety days, visibility rapidly deteriorates. Summer rubber wiper blades harden and leave streaks, so switch to winter wipers (snow wipers). They have softer rubber parts with a structure that resists freezing. Recommended products: PIAA "Snow Super Silicone" and BOSCH "AeroTwin Snow" among others.
For washer fluid, "-22°F compatible types" with antifreeze functions are recommended. They can be purchased at home centers or online retailers for around $3 per bottle.
Stocking Up on Freeze and Snow Countermeasure Supplies
For winter roads, it's important to keep cold weather and emergency supplies in your car to prepare for sudden snow or freezing conditions.
Recommended items:
- Snow brush and scraper: For clearing snow from windshields and roofs.
- Tire chains (non-metal type): Convenient for sudden snowfall.
- De-icing spray: Essential for unlocking frozen door locks and windshields.
- Thermal blanket and gloves: Backup for traffic jams or being stranded.
Winter Preparation Checklist When Purchasing a Used Car
When purchasing a used car, checking the following in advance will ensure peace of mind in winter:
- Battery manufacture date and voltage
- Tire tread depth and manufacture date
- Wiper and light operation confirmation
- Air conditioning and heater effectiveness
- Coolant and oil replacement history
On used car listing sites like "Cartree," many vehicles allow you to check maintenance history along with vehicle information, so checking at the time of purchase can prevent winter troubles in advance.
Recommended Vehicles for Winter Conditions
If you're looking for a vehicle strong on snowy roads, 4WD (four-wheel drive) or AWD (all-wheel drive) models are recommended. Considering fuel efficiency and maintenance costs, popular SUVs or light 4WD models are a good target.
Popular model examples:
- Suzuki Hustler 4WD (strong on snowy roads despite being a light SUV)
- Toyota Yaris Cross 4WD (balance of safety features and fuel efficiency)
- Subaru Forester (equipped with Subaru's proprietary AWD technology "Symmetrical AWD")
These vehicles are also popular in the used car market with stable pricing. If you're looking for a car to drive in winter, pay attention to equipment and drivetrain type when selecting.
Winter Car Washing and Body Care
Driving on roads treated with calcium chloride (de-icer) makes the undercarriage prone to rust. Even in winter, wash your car regularly and don't forget underbody cleaning. Also, applying water-repellent coating makes snow and mud less likely to stick, making maintenance easier. Recommended products: Surluster "Zero Water," Soft99 "Rain Drop," and others.
Summary: Early Preparation Protects Safety
Most winter car troubles are caused by minor maintenance oversights. Inspect basic components like tires, battery, oil, and wipers early and replace them as needed. Also, it's wise to purchase winter tires and freeze countermeasure supplies before the season. All of these are essential items for safe winter driving.
