Sumitomo HTR Z5 225/40R18 ZR 92Y XL HTR78

Sumitomo HTR Z5. FEATURES AND BENEFITS: Summer weather traction; High speed controllability; Comfortable driving experience; . OVERVIEW: The Sumitomo HTR Z5 is a high performance, summer tire made for passenger vehicles and SUVs.The model offers great summer traction. This tread design and summer compound improve dry and wet grip. In this manner, the optimal tread pattern maintains road contact in dry and wet conditions, while the compound prevents heat build-up in warm temperatures. On the other hand, wide circumferential grooves prevent hydroplaning, by eliminating water from the footprint in wet situations. These elements guarantee a safe summer performance.The asymmetric tread design and its consistent road contact improve controllability. In other words, close road contact upgrades steering responsiveness and driving stability. The steering response time is faster and more precise to the driver's commands, while the structure is secured against driving pressure. At the same time, wide shoulder blocks firmly grip the road surface and increase maneuvering. The strengthened internal structure and durable rubber compound enhance the high speed performance. This construction does not allow the tire to deform under pressure, while the rubber compound prevents heat build-up along the tread area. As a result, this construction and rubber compound boost its high speed durability.The Sumitomo HTR Z5 also offers a quiet and comfortable driving experience. This asymmetric tread design allows the tire to prevent sound waves from reaching the vehicle's cabin and ruining the passengers' driving enjoyment. The tread design allows the tire to generate a sound-canceling frequency to achieve this. This promotes an enjoyable performance.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.
