1. Why 3PMSF Winter Tires Matter in the Maritimes
Maritime winters bring drastic temperature swings, black ice, slush, and heavy coastal snowstorms. Standard all-season tires harden when temperatures drop below 7°C (45°F), reducing traction significantly.
Look for the Three-Peak Mountain Snowflake (3PMSF) symbol on the tire sidewall. This rating guarantees the tire meets official snow traction requirements for extreme winter weather.
2. Studded vs. Non-Studded Winter Tires
Studded Winter Tires
Best for rural Maritime roads, freezing rain, and hard-packed ice. Metal studs bite directly into ice for unmatched braking grip.
Studless Friction Tires
Best for city driving (Moncton, Saint John, Fredericton). Specialized silica rubber compounds grip wet slush and cold dry asphalt quietly.
3. When Should You Install Winter Tires in NB?
The general rule in New Brunswick is mid-October to early November, or as soon as nighttime temperatures consistently drop below 7°C. Waiting for the first major snowfall leads to long shop wait times and hazardous driving conditions.
