About This Tire

The Kumho Ecsta Sport A/S 235/55R17 is a summer tire, designed for sporty coupe, sports car, and performance sedan drivers who prioritize responsive handling and high-speed traction in warm weather conditions. Its tread design and compound focus on dry grip performance, wet weather capability, and driver comfort through advanced silica-polymer construction.

The tire features a high-grip resin compound that combines silica and polymers for enhanced dry traction and wear life, molded into an asymmetric tread pattern optimized for control and comfort. Stiffened outside shoulders resist deformation during cornering, while rounded block edges help absorb road impacts, and K-Noise Defender technology uses airflow-disrupting dimples within the grooves to reduce road noise. Driver feedback points to strong performance in both wet and dry conditions, with notable comfort levels and responsive handling characteristics.

Compared to traditional all-season tires, it emphasizes summer performance capabilities and sporty driving dynamics over cold weather versatility. Overall, it's a solid choice for performance vehicles used primarily for spirited driving and daily commuting in warm weather climates.
