The Kumho Ecsta PS31 is an ultra-high performance summer tire designed for drivers of sports cars, sporty coupes, and performance sedans who prioritize responsive handling and confident grip in both dry and wet conditions. It offers a balance of performance and value, making it a compelling option in its category.
The Ecsta PS31 features a directional tread pattern with a solid center rib, contributing to enhanced high-speed stability and steering response. The tire's design incorporates wide circumferential grooves to effectively evacuate water, reducing the risk of hydroplaning in wet conditions. Lateral grooves are also implemented to maximize water displacement during cornering and to promote even wear. A 3D dimple design helps to minimize heat build-up in the tread blocks, which enhances the tire's durability and high-speed performance. The tire also features microgrooves with diagonal siping to further aid in water drainage.
The tire's internal construction includes a two-ply polyester casing beneath twin wide steel belts and two full-layer nylon cap plies. This reinforced construction improves impact resistance, handling at higher speeds, and overall durability. The Kumho Ecsta PS31 has a UTQG treadwear rating of 400. The sidewall features a racing-inspired checkered design.
