Hankook Ventus Prime2 HRS (*). FEATURES AND BENEFITS: Summer weather traction; Run flat tire model; High speed performance; Enhanced controllability; . OVERVIEW: The Hankook Ventus Prime2 HRS (*) is a performance and high performance, depending on the speed rating of the specific tire shape, run flat summer tire manufactured for passenger vehicles. This model is the original equipment tire of select BMW vehicles.The tire was manufactured with Hankook's run flat technology. This model has a strengthened internal structure that is capable of maintaining the tire's shape in case of air pressure loss. When air pressure leaves the tire due to a puncture or other damage, the construction withstands the weight of the vehicle and its passengers for 50 miles up to the speed of 50 miles. This prevents the driver from being stuck on the side of the road and allows them to safely arrive at a nearby location to fix or change the tire. Run flat tires are usually manufactured for vehicles that have no space for a spare tire. They cannot be used on the same vehicle with regular tires due to their heavier internal structure. The Hankook Ventus Prime2 has some run flat and non-run flat sizes as well.The tire promotes excellent summer weather traction. The asymmetric tread pattern and the summer weather compound improve the grip on dry and wet weather. The special summer compound offers excellent rubber flexibility in hot weather, actively preventing heat build-up along the tread area. The special triple radius tread profile improves the wet weather traction. It features three different tread areas, a combination which enhances the tire's gripping capability in wet conditions. This combined with the tire's excellent hydroplaning resistance improves the tire's summer weather driving safety.The asymmetric tread design upgrades the model's controllability. The asymmetric tread pattern's continuous center ribs maintain the tire's contact with the road surface at all times. In this manner, the tire increases its steering responsiveness and driving stability. The constant road contact boosts the steering response time and precision, while it also stabilizes the structure against the driving pressure affecting the model. The larger shoulder tread area with the optimal block design increases the cornering capability and power. The tread upgrades the number of biting edges gripping the road surface throughout the tire's lifetime, which enhances the cornering and maneuvering capability and power.The Ventus Prime2 HRS (*) ensures excellent high speed performance. The asymmetric pattern features a bionic design with jaguar tooth shaped notched on the ribs. These significantly enhance the tire's grip on the road surface, even during its high speed performance. They firmly grip the road surface to guarantee the tire's constant contact with the road surface. The summer weather compound prevents heat from building up on the tire's surface, which improves the high speed performance by easing the driving pressure off the tire. In this manner, the tire ensures a secure high speed driving experience in summer weather. 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.
