Armstrong's Ski-Trac HP is a studless winter tire that's designed for use on performance-oriented coupes and sedans. Built with a special rubber compound that enhances performance and stability in sub-freezing temperatures, the Ski-Trac HP also features a directional, V-shaped tread pattern that boosts high-speed performance while also funneling water out of the tread to increase hydroplaning resistance. Additionally, the Ski-Trac HP's 3D shoulder sipes improve grip on icy and snowy roads by creating additional biting edges.
