Kumho 245/40 R17 95Y Ecsta PS71 2024

Kumho Ecsta PS71 245/40 R17 95Y XL is an ultra-high-performance summer tyre designed for passenger cars requiring a 17-inch fitment. This exact configuration uses a 245 mm section width, 40-series profile and 17-inch rim, with a 95Y XL service description. Load index 95 corresponds to a maximum load of 690 kg per tyre, while the Y speed rating allows speeds up to 300 km/h under the specified operating conditions.

Tread Design and Steering Response

The Ecsta PS71 uses a performance-oriented tread design developed to provide precise steering response and stable road contact. Its central tread structure supports straight-line stability, while the shoulder areas are designed to maintain controlled response during steering inputs and cornering.

Dry-Road Handling and Cornering

The 245 mm footprint and low 40-series profile provide a broad contact area and relatively direct steering characteristics. The reinforced XL construction helps support the tyre under higher loads and dynamic cornering forces, making this configuration suitable for performance-oriented passenger-car applications.

Wet-Road Performance

The Ecsta PS71 incorporates four wide longitudinal grooves designed to evacuate water from the contact area. Kumho also uses a high-dispersible micro-silica tread compound intended to support wet-road grip and braking performance. The exact 245/40 R17 95Y XL configuration is listed with an EU wet-grip rating of A.

High-Speed Stability and Braking

The reinforced belt and bead construction is designed to provide precise and stable handling at higher speeds. Kumho positions the Ecsta PS71 as an ultra-high-performance tyre with strong dry- and wet-road handling and braking characteristics. The 95Y specification provides a maximum load rating of 690 kg per tyre and a Y speed rating of up to 300 km/h, subject to the applicable load, inflation pressure and vehicle manufacturer's requirements.

Comfort and Road Noise

The low-profile 40-series construction prioritizes steering response and handling over maximum ride cushioning. For this exact configuration, the EU tyre label lists external rolling noise at 72 dB with a B noise classification. Actual cabin noise and ride comfort depend on vehicle suspension, tyre pressure, road surface and vehicle configuration.

Seasonal Performance

The Kumho Ecsta PS71 245/40 R17 95Y XL is classified as a summer tyre. It is designed primarily for warm-weather paved-road driving and performance-oriented applications rather than winter or severe-snow conditions.

Load Capacity and Speed Rating

The 95 load index corresponds to a maximum load of 690 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h, subject to the manufacturer's load and inflation requirements and the vehicle manufacturer's specifications.

Who Should Consider This Tyre?

Kumho Ecsta PS71 245/40 R17 95Y XL is suitable for compatible passenger cars requiring this exact fitment. It is particularly suited to drivers seeking precise steering, strong dry-road handling, wet-road grip, high-speed stability and responsive braking performance.
