The tread pattern features a high-density zigzag siping placement on the stabilized tread elements and a detailed groove and notch placement work together to firmly grip the ice- and snow-covered road surface conditions. The Multi-Cell compound with the silica elements is Bridgestone's best winter compound, which maintains the flexibility of the rubber elements in versatile temperatures. This combination enables the tire to securely perform in the harshest winter conditions, without the use of studs. The tread's circumferential and lateral groove and notch placement also allows the tire to actively prevent hydroplaning. As a result, the tire can securely perform in harsh winter conditions, which has earned the tire its three mountain peak and snowflake symbol.
