About This Tire

The Kumho Ecsta Sport 205/40R17 is a summer tire, designed for luxury car, sporty coupe, and performance sedan drivers who prioritize precision handling and exhilarating performance in everyday driving. Its tread design and compound focus on maximizing grip and responsiveness through an asymmetric pattern with dedicated wet and dry weather capabilities.

The tire features a solid center rib for high-speed stability and braking, paired with a robust outboard shoulder that provides the stiffness needed for hard cornering and aggressive maneuvers. Four circumferential main grooves work with optimized lateral grooves to evacuate water from the footprint, while the dedicated summer compound is built on a two-ply polyester casing for structural integrity. Driver feedback points to exceptional wet and dry traction with reliable comfort and solid treadwear performance in daily use.

Compared to all-season tires, it prioritizes maximum warm-weather performance and handling precision over year-round versatility. Overall, it's a solid choice for performance vehicles used primarily for spirited driving and daily commuting in warm weather conditions.
