The snowflake-on-the-mountain symbol is branded on the sidewall of tires that have superior snow traction. Studless Ice and Snow tires will have this branded on their sidewall as well as Performance Winter / Snow tires. Some On-/Off-Road All-Terrain truck tires have snow traction that is good enough to receive the snowflake-on-the-mountain symbol, as well.
