Kumho Ecsta PS31 Summer Ultra-High Performance Tire

The Kumho Ecsta PS31 is a summer ultra-high performance tire engineered for driving enthusiasts who demand exceptional handling, confident wet-weather capability, and a dynamic driving experience. Built on a silica-enriched compound blended with high-grip resin, the Ecsta PS31 delivers the dry grip and wet traction that performance-oriented drivers expect from a dedicated summer tire — without sacrificing ride comfort or everyday usability. Designed for sports sedans, performance coupes, and sporty passenger cars, the PS31 strikes an impressive balance between exhilarating performance and real-world practicality.

Advanced Tread Technology:

• Directional tread pattern with solid center rib reinforces block stiffness for improved wet braking performance and precise, responsive steering feedback
• Wide four-channel circumferential grooves rapidly evacuate water from the contact patch to effectively resist hydroplaning in wet conditions
• Optimized lateral groove angles maximize water displacement during cornering while promoting even, consistent tread wear
• Microgrooves with diagonal siping create additional biting edges throughout the tread for enhanced wet traction and efficient water drainage

Durability and High-Speed Performance:

• 3D dimple design minimizes heat build-up on tread blocks, extending tire durability during sustained high-speed driving
• Reinforced internal structure supports high-speed stability and long-term casing integrity
• Computer-optimized tread pattern reduces road noise and vibration for a quieter, more comfortable ride
• Racing-inspired checkered sidewall design reflects the tire's ultra-high performance character with a bold, aggressive appearance

Summer-Use Notice: As a dedicated summer performance tire, the Ecsta PS31 uses a high-grip rubber compound optimized for warm-weather conditions. It should not be used when temperatures consistently fall below 45°F (7°C), as the compound will harden and traction will be significantly reduced. For year-round driving, a separate all-season or winter tire is strongly recommended.

Warranty: The Kumho Ecsta PS31 is backed by a Road Hazard Warranty, covering tires damaged by road hazards within the first 12 months of purchase or until the first 3/32" of tread wear, whichever comes first. No mileage warranty applies to this tire line.

Backed by Kumho's 60+ years of global tire manufacturing expertise, the Ecsta PS31 delivers an impressive combination of exhilarating dry performance, confident wet-weather handling, and a surprisingly comfortable summer driving experience — all at a price point that represents exceptional value in the ultra-high performance category.
