Kumho Ecsta V720. FEATURES AND BENEFITS: Summer weather traction; Enhanced controllability; High speed performance; . OVERVIEW: The Kumho Ecsta V720 is a high performance, summer tire manufactured for passenger vehicles and SUVs.Summer weather traction is upgraded with the durable compound and the asymmetric tread design. The rubber elements of the durable, finer carbon black compound help to effectively prevent heat build-up across the tread area. The asymmetric tread design with the ribbed footprint upgrades the surface traction in dry and wet weather conditions with the use of extra biting edges. The footprint's ideal groove placement allows the tire to improve the hydroplaning resistance by dispersing water from the footprint. The combination of these improvements upgrades the tire's secure summer weather performance.The tire's better controllability is improved as well. The ribbed tread design and the ESCOT technology work together to upgrade the surface contact. This technology optimizes the tire's bead, sidewall, and shoulder structure's tension which ensures the surface contact and the pressure circulation across the tread area. This enables the tire to boost the steering responsiveness and the driving stability. The shoulder block pattern with the siping placement upgrades the cornering and maneuvering ability at all times. The asymmetric tread and the carbon black compound generate friction during braking, which greatly shortens the braking distance. This results in the driver's better control over the vehicle at all times.The Ecsta V720 boosts the high speed performing power. The heat-resistant compound and the reinforced construction manage to ensure the tire's high speed durability. The compound prevents heat build-up across the tread area, optimizing the performing ability and power. The structure does not deform under pressure, which enables the tire to securely improve its overall durability. This combination enables the tire's better high speed driving experience. 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.
