Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.

Prep your car. Fill up your gas tank,

pack jumper cables, ice scraper, warm clothing, snacks and water.
