Kumho 255/45 R20 105V Ecsta PS71 2024

Kumho Ecsta PS71 255/45 R20 105V XL is a high-performance summer tyre designed for compatible passenger cars and SUVs requiring a 20-inch fitment. This exact configuration uses a 255 mm section width, 45-series profile and 20-inch rim, with a 105V XL service description. Load index 105 corresponds to a maximum load of 925 kg per tyre, while the V speed rating allows speeds up to 240 km/h under the specified operating conditions.

Tread Design and Steering Response

The Ecsta PS71 uses an asymmetric tread pattern developed to provide stable road contact and responsive steering. Its tread structure is designed to support predictable directional response during straight-line driving, lane changes and cornering, while the reinforced XL construction helps maintain stability under higher loads.

Dry-Road Handling and Cornering

The 255 mm footprint provides a broad contact area for dry-road grip and stable cornering. The 45-series profile gives the tyre a relatively direct steering character, while the performance-oriented tread design supports controlled handling during acceleration, braking and cornering on paved roads.

Wet-Road Performance

The Ecsta PS71 incorporates four wide longitudinal grooves designed to evacuate water from the contact patch. Kumho's performance-oriented silica compound is intended to support wet-road grip and braking. The exact 255/45 R20 105V XL configuration carries an EU wet-grip rating of A, although actual performance depends on tyre condition, inflation pressure, road surface and vehicle setup.

High-Speed Stability and Braking

The reinforced internal construction and asymmetric tread are designed to provide stable road contact and controlled handling at higher speeds. The 105V specification provides a maximum load rating of 925 kg per tyre and a V speed rating of up to 240 km/h, subject to the applicable load, inflation pressure and vehicle manufacturer's requirements.

Comfort and Road Noise

The 45-series profile prioritizes handling response while retaining practical road comfort for everyday driving. For this exact 255/45 R20 105V XL configuration, the EU tyre label lists external rolling noise at 73 dB with a B noise classification. Actual cabin noise and ride comfort depend on suspension setup, road surface, tyre pressure and vehicle configuration.

Seasonal Performance

The Kumho Ecsta PS71 255/45 R20 105V XL is classified as a summer tyre. It is designed primarily for warm-weather paved-road driving, with an emphasis on dry handling, wet-road grip and high-speed stability rather than winter or severe-snow performance.

Load Capacity and Speed Rating

The 105 load index corresponds to a maximum load of 925 kg per tyre. The V speed rating corresponds to a maximum rated speed of 240 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 255/45 R20 105V XL is suitable for compatible passenger cars and SUVs requiring this exact fitment. It is particularly suited to drivers seeking responsive steering, strong dry-road grip, reliable wet-road traction, stable highway handling and reinforced load capability.
