Haida SCEPHP HD668 . FEATURES AND BENEFITS: All season performance; Longer lasting tread life; Fuel efficient drive; High speed controllability; . OVERVIEW: The Haida SCEPHP HD668 is a performance, all season tire made for passenger vehicles and SUVs, with some highway terrain sizes for light trucks. It also offers touring sizes for passenger vehicles.The strong compound materials and ribbed tread design ensure a phenomenal year round performing ability. The ribbed tread elements, with the sipe detail, boost the traction on dry, wet, and snow-covered road surfaces, while the compound keeps the rubber flexible all the time. The tread provides a high number of biting edges and optimizes year-round performance. The circumferential and lateral grooves channel water and slush away from the footprint. This allows the tire to actively resist the risk of hydroplaning on wet and snowy roads.The ideal tread pattern is able to lower the rolling resistance throughout the performance and promote a fuel efficient drive. These tread elements closely follow the driving surface, which lowers the rolling resistance as a result. The rolling resistance determines how much energy is used to keep the tires in motion, and lowering it reduces the fuel intake and CO2 emissions. It offers a cost efficient and eco-friendly driving experience.The ribbed tread elements boost the controllability and driving stability by maintaining a consistent contact with the driving surface. The detailed tread ribs with sipe detail provide a high number of biting edges, boosting the steering responsiveness and accuracy to the drivers instructions. It enables the driver to maintain an excellent control over the vehicle, promoting a better and safer high speed performance. The heat-resistant compound, on the other hand, avoids heat build-up across the tread area, further boosting the high speed durability.The Haida SCEPHP HD668 is able to perform remarkably well throughout the year, thanks to the durable compound materials and ideal tread elements. The compound keeps the rubber flexible in both summer and winter temperatures, while circumferential and lateral grooves channel water and slush away from the footprint. This prevents the tire from hydroplaning in snowy and rainy weather conditions. The tread ribs boost traction on dry, wet, and snowy roads. It offers better year round maneuvering 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.
