The Cooper CS5 Ultra Touring All-Season 225/50R17 94V Tire with innovative technologies, such as an improved compound, Wear Square Visual Indicator, 3D Micro-Gauge sipes and STABILEDGE, provides real-life performance in real-life conditions for everyday drivers. If you want to feel connected to the road, the CS5 Ultra Touring does just that with the patented STABILEDGE technology. STABILEDGE technology can be found on the edge of the tread elements. It stabilizes the tread while driving which provides superior dry traction, handling and overall steering response. The asymmetric tread design of the CS5 Ultra Touring is designed to deliver a crisp steering response, controlled handling around curves and all-season road gripping capabilities. The specially designed 3D Micro-Gauge sipes stabilize the tread elements by interlocking them together to maximize surface contact. This additional surface contact and increased number of biting edges greatly improves traction in wet and light snow conditions. The tread compound gives the CS5 Ultra Touring superior wet handling, shortens stopping distance and lowers rolling resistance for improved fuel mileage.
