The Latitude X-Ice Xi2 is Michelin's Studless Ice and Snow winter tire developed for the drivers of vans, crossover and sport utility vehicles, as well as light-duty pickups that want a boost in winter driving confidence. Latitude X-Ice Xi2 winter tires are designed to combine X-tra ice and snow traction with enhanced handling on wet and dry roads. Michelin's FleX-Ice silica-based winter tread rubber compound (offers firmness at higher temperatures for wet and dry road stability while it remains flexible at lower temperatures to enhance packed snow and ice traction) is molded into a directional tread design that helps evacuate water and slush to improve hydroplaning resistance. Independent shoulder and intermediate tread blocks feature a combination of multiple micro-pumps and Cross Z-Sipes to deliver traction on ice- and snow-covered roads. Additionally, the Cross Z-Sipes increase tread and shoulder block stability to provide the lateral and longitudinal stiffness that enhances driving precision on dry and wet roads. The tire's internal structure includes twin steel belts reinforced by spirally wound polyamide cord to optimize the tire profile while enhancing high-speed capability. Latitude X-Ice Xi2 winter tires meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol. NOTE: Snow platform indicators (the equivalent of "snow wear bars") are molded into the Latitude X-Ice Xi2's tread grooves to inform the driver when ice and snow traction will be reduced as the tire's tread wear reaches the point where the remaining tread depth becomes less effective in deep snow. Install Latitude X-Ice Xi2 tires in sets of four only. Due to the traction capabilities of the Latitude X-Ice Xi2, Michelin recommends using Latitude X-Ice Xi2 tires in sets of four to provide the best handling characteristics and tire performance.
