Kumho 2268043 Ecsta PS31 235/45ZR18 98W XL Ultra High Performance Summer Tire

The Kumho Ecsta PS31 is an ultra-high performance summer tire engineered for sports cars, sporty coupes, and performance sedans that demand confident grip and precise handling in both dry and wet conditions. Built around a high-technology summer compound with High Dispersible Micro Silica and High Grip Resin, the PS31 delivers enhanced traction across the contact patch at speed.

Key Features:

• Solid Center Rib: Reinforces tread block stiffness for improved high-speed stability, steering responsiveness, and wet braking performance.
• Wide Lateral Grooves: Optimized 0–10 degree angle range maximizes water displacement during cornering and resists irregular tread wear.
• Four Wide Circumferential Grooves: Four full-depth channels work continuously to evacuate water from the footprint and improve hydroplaning resistance.
• 3D Dimple Design: Heat dimples embedded in the tread blocks minimize heat buildup at high speeds, increasing tread durability and reducing wear.
• Diagonal Sipe Microgrooves: Efficiently channel water away from the contact patch, providing an additional layer of hydroplaning protection.
• Racing-Inspired Checkered Sidewall: Bold sidewall styling that reflects the tire's ultra-high performance character.
• Extra Load (XL) Rated: Higher load capacity at 1,653 lbs per tire with a maximum inflation pressure of 50 PSI.

Rated 460 A A (UTQG), the Ecsta PS31 offers a strong blend of treadwear longevity, superior traction, and excellent heat resistance. With a 10/32" tread depth and black sidewall finish, this tire is a compelling choice for performance-focused drivers seeking summer grip without sacrificing everyday drivability.

Note: As a summer performance tire, the Ecsta PS31 is not intended for use in near-freezing temperatures, snow, or icy conditions.
