About Kumho Ecsta PS71 EV 255/45R20 101V

Wet-Road Performance

The Ecsta PS71 EV is designed to provide strong grip and stable handling on wet roads. Its tread and compound are engineered around the braking and handling requirements of high-performance passenger cars and electric vehicles, while the longitudinal grooves help manage water in the contact area.

Wet Braking

The exact 255/45R20 101V specification carries an A wet-grip rating. This indicates a high level of wet-road braking performance under the applicable European tyre-label classification.

Dry-Road Handling

Kumho positions the Ecsta PS71 as a high-performance tyre with precise handling and stable behaviour at higher speeds. The asymmetric tread pattern and performance-oriented construction help maintain controlled steering response during cornering and directional changes.

Ride Comfort and Noise

The exact specification has an external rolling-noise level of 71 dB and noise class B. The EV-oriented construction is designed to balance performance requirements with controlled road noise for modern electric and premium passenger vehicles.

Rolling Resistance

The exact 255/45R20 101V EV specification carries a B fuel-efficiency rating. This provides a relatively efficient rolling-resistance classification while retaining the performance characteristics expected from an ultra-high-performance tyre.

Summer Road Use

The Ecsta PS71 EV is a summer tyre intended for warm-weather road use. The exact specification does not carry the 3PMSF severe-snow marking and should therefore not be considered a dedicated winter tyre.

Load Capacity

The 101 load index corresponds to a maximum load of 825 kg per tyre under the specified operating conditions. This capacity is suitable only when the vehicle manufacturer approves the 255/45R20 101V specification.

V Speed Rating

The V speed symbol indicates a maximum rated speed of 240 km/h. Actual vehicle speed should always remain within the limits specified by the vehicle manufacturer and applicable road regulations.

Vehicle Compatibility

The 255/45R20 101V Ecsta PS71 EV is intended for passenger cars, SUVs, and electric vehicles requiring this size and service description. Kumho specifically identifies the EV version as a tyre developed for electric-vehicle applications. Vehicle compatibility should always be checked against the manufacturer's approved tyre size, load index, speed rating, and EV requirements before fitting.
