The Sprint Classic is Vredestein's Grand Touring Summer tire developed for drivers of classic automobiles who want a tire with vintage style combined with modern technology. Like all summer tires, the Sprint Classic is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.Sprint Classic tires feature a summer compound molded into a symmetric tread design with a classic look. The solid rib pattern with closed shoulders delivers confident straight-line tracking on the road, and the modern radial construction provides the foundation for handling capabilities that far exceed the bias-ply tires the Sprint Classic resembles. Multiples sipes within the tread ribs create additional biting edges for improved wet grip, and the deep, circumferential grooves allow water to flow through the contact patch away from the footprint for improved hydroplaning resistance.The tire's internal structure includes twin steel belts on top of a single-ply (215/70R15 is two-ply) rayon casing.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 Grand Touring Summer tires during cold-weather use can result in irreversible compound cracking. While 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.
