Kumho Ecsta V730. FEATURES AND BENEFITS: High speed performance; Enhanced controllability; Summer weather traction; . OVERVIEW: The Kumho Ecsta V730 is a high performance, summer tire manufactured for racing vehicles.This model was designed and produced with a reinforced internal structure. The construction features a high-strength carcass and apex deformation prevention, which strengthen the tire against high speed pressure. They maintain the ideal tire shape under driving pressure, enabling the tire to ensure a safer performance. The tread's heat-resistant compound and the wave-shaped micro-groove pattern ease the pressure off the tire, minimizing pressure accumulation along the tread area. This combination guarantees the tire's safer high speed durability, enabling its secure racing applications.The minimalistic, asymmetric tread design uses its continuous elements to maintain surface contact at all times. It greatly improves steering responsiveness and driving stability, allowing exceptional handling. In other words, the rib type center block design ensures its exceptional straight-line stability, which also optimizes its steering response and accuracy. The wider outer shoulder pattern enables the tire to upgrade its cornering power. These elements firmly grip the road, enhancing maneuvering. The tread design also uses the road-to-rubber ratio and heat resistance to enhance its braking capability.The Ecsta V730 also greatly improves summer weather traction. The combination of the heat-resistant compound and asymmetric tread design enhance the excellent dry and wet grip. Stronger compound elements avoid heat build-up across the tread area, while better road contact boosts surface traction. The circumferential grooves and special zigzag-shaped center under-groove pattern avoid hydroplaning. The grooves channel water from the footprint, avoiding hydroplaning in the process. 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.
