The X-ICE SNOW is Michelin's Studless Ice & Snow winter tire developed for drivers of coupes, sedans, minivans and crossovers looking for confidence in winter's many different road conditions, throughout the life of the tire. Whether it's clear, cold winter roads; deep, heavy snow; or any icy condition in between, the X-ICE SNOW is designed to deliver reassuring wintertime traction and stability. The FleX-Ice™ 2.0 compound of the X-ICE SNOW utilizes inclusion technology, which generates micro-roughness on the tread surface, helping improve grip both in snow and on ice. The compound also contains a high silica content that ensures the tire maintains its flexibility, even in severe climates. This advanced compound is molded into a continuous V-Shape, directional tread pattern with increased groove widths compared to its predecessor, engineered to improve hydroplaning and slush performance, as well as increase the snow-to-snow traction needed for loose conditions. The X-ICE SNOW' s tread elements contain two types of full-depth sipes with complementary traction effects. Notched sipes provide numerous biting edges that help enhance traction in adverse conditions, along with variable thickness sipes that further aid traction while supporting the tread elements to maintain an efficient contact patch for control on packed snow and clear roads.X-ICE SNOW Studless Ice & Snow tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.Install Michelin X-ICE SNOW tires in sets of four only.Due to the traction capabilities of X-ICE SNOW tires, Michelin recommends using them only in sets of four to provide the best handling characteristics and tire performance.
