The ExtremeContact Sport is Continental's Max Performance Summer tire developed for the drivers of sports cars, performance sedans and powerful luxury vehicles looking to combine serious performance in the dry and wet with refined ride and noise comfort. Like all summer tires, the ExtremeContact Sport is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice. Utilizing a specialized summer-only compound molded into a five-rib (six-rib in some sizes), asymmetric design, the ExtremeContact Sport features Continental's SportPlus Technology, which focuses on delivering precise handling, wet traction and enhanced wear for well-rounded maximum performance. The outside shoulder features wide tread blocks for lateral grip and high-speed handling, and the continuous center rib provides constant rubber-to-road contact for solid on center feel, while an optimized footprint evenly distributes pressure across the face of the tire for improved tread life. Continental's patented +Silane tread compound technology delivers the grip needed for sure-footed handling in damp conditions, and the deep, circumferential grooves provide a direct path for water to flow through the contact patch, reducing the risk of hydroplaning. Quickview Performance Indicators molded into the tread pattern provide at-a-glance awareness of the tire's suitability for use in dry and wet conditions. The internal construction of the ExtremeContact Sport consists of a polyester or rayon cord (depending on size) body casing and two-ply sidewall construction to add sidewall stiffness without compromising ride comfort. The casing ply supports two high-tensile steel belts, and two spirally wound polyamide cap plies reinforce the structure for high-speed capability. Note:: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle. Flexing of the specialized rubber compounds used in Max Performance Summer tires during cold-weather use can result in irreversible compound cracking. Compound cracking is not a warrantable condition because it occurs as the result of improper use or storage, tires exhibiting compound cracking must be replaced.
