Continental ExtremeContact Sport. FEATURES AND BENEFITS: Longer lasting tread life; Summer weather traction; Easy handling at high speeds; High speed performance; . OVERVIEW: The Continental ExtremeContact Sport is a high performance, summer tire manufactured for passenger vehicles and SUVs.This model offers great wet and dry weather road grip and it will maintain its traction throughout the summer months thanks to its excellent tread design. The tire was manufactured with the +Silane tread compound, which improves the wet traction and road grip of the tire, even when driving at higher speeds. It is not suitable for use in winter weather or in colder temperatures, as the rubber will lose its traction due to the cold air. The circumferential grooves in the tread eliminate water from below the footprint of the tire, enhancing its resistance to hydroplaning.This model has a longer lasting tread life. The optimized tread design and the footprint extend the tire's life by preventing irregular wear. When a tire's wear is uneven, it causes vibrations and bounciness felt in the cabin of the vehicle. Not only is that uncomfortable for the passengers, it can also potentially harm the axle of the vehicle. As the tire is forced to wear out evenly, it will not cause discomfort and it can be used for a longer period of time.The ExtremeContact Sport ensures excellent performance. Its high speed stability and performance are exceptional in both dry and wet weather road conditions. The tire's reinforced internal structure also enhances its high speed performance capability, while the Sport Plus Technology used in its production increases its handling and grip at high speeds. The Sport Plus Technology's main focus is to provide accurate handling in wet and dry traction to bring out the tire's highest performing ability. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
