<p>Armstrong Blu-Trac HP is an ultra-high-performance all-season tire made for passenger vehicles. It features four wide circumferential grooves that help to evacuate the water and slush away from the tire’s footprint, improving holding and traction, as well as reducing the chances of hydroplaning. Various sipes on the inner three ribs create extra gripping surface for enhanced safety and ride comfort. The sub-straight grooves on the outer shoulders of the Blu-Trac HP tire help to significantly improve cornering precision and overall vehicle stability. The innovative silent groove wall assists in noise reduction by evenly distributing the air flow through the vertical serrations.</p>
