There are two common grading systems for tires to help identify winter tire traction capabilities. All tires that pass certain winter tire traction tests can be marked with a symbol molded onto the side of the tire. One is the M+S (mud and snow) symbol, and the second is the mountain/snowflake symbol.

Tread wear indicator bars are moulded into the tread grooves at regular intervals around the tyre to indicate when a tyre is worn to its limit of safety. The minimum legal tread depth is 1.5 mm across the width of the tread. When the tyre is worn to the legal limit the bars will be flush with the surface of the tread.
