Kumho 2206453 Ecsta PS71 Ultra High Performance Summer Tire

The Kumho Ecsta PS71 is an ultra high performance (UHP) summer tire engineered for passenger cars, sport sedans, and performance vehicles demanding confident grip and precise handling in both wet and dry conditions. Built on racing-derived technology, the PS71 delivers a compelling balance of performance and value in the competitive UHP summer tire segment.

Key Features:

• Asymmetric Tread Design: Optimized for UHP summer applications, the asymmetric pattern delivers confident cornering stability and responsive steering feedback at all speeds
• High-Dispersion Micro Silica Compound: Advanced compound technology maximizes wet and dry grip, improves handling performance, and enhances fuel efficiency
• Four Circumferential Drainage Grooves: Wide main grooves efficiently evacuate water from the contact patch, providing outstanding aquaplaning resistance and short wet braking distances
• Hybrid Cap Ply Construction: Reinforced casing with strengthened, rigid sidewalls promotes precise steering response and high-speed stability
• 3D Block Cooling System: Three-dimensional tread blocks and an integrated cooling system reduce heat buildup during sustained high-speed driving
• Multi-Functionalized S-SBR Polymer: Specialized polymer blend maximizes wet traction and wear performance simultaneously
• Racing-Inspired Sidewall Design: Sport-themed tread and sidewall graphics reinforce the PS71's performance character

The Ecsta PS71 is a summer-only tire and is not rated for winter or snowy conditions. For cold weather driving, Kumho recommends transitioning to a dedicated winter tire. The PS71 has earned recognition in independent magazine tests for its aquaplaning resistance, braking performance, and price-to-performance ratio, and is approved as original equipment (OE) on select Kia, Hyundai, and Skoda models.
