What Is the 3-Peak Mountain Snowflake Rating.

If you spend any time exploring mountain roads, chasing winter powder days, or just living life in Colorado, you know the weather can go from sunny and 50° to blizzard-mode in hours. That’s part of the magic here — but also a serious curveball if your van isn’t set up for it.

Enter the 3-Peak Mountain Snowflake (3PMSF) rating.

Three-Peak-Mountain-Snowflake

This symbol on your tire sidewall certifies that the tire has passed performance-based traction tests in severe snow, ice, and slush. It’s not a marketing term — it's a standardized rating showing the tire truly delivers when conditions get unpredictable.

What Does 3PMSF Mean for Van Owners?

Tires with the 3PMSF rating provide:

  • Better traction in snow & slush

  • Improved braking in winter conditions

  • More confident handling on ice-covered roads

  • Peace of mind when winter strikes without warning

For year-round adventurers, this rating matters. It means you can chase winter solitude, ski days, and snow-covered trailheads without swapping to a dedicated winter setup every season — as long as you choose the right all-terrain tire.
