Kumho Ecsta PS71 EV 255/50 R19 107Y is a summer performance tyre developed for high-performance passenger cars and electric vehicles requiring a 19-inch fitment. This exact configuration features a 255 mm section width, 50-series profile and 19-inch rim, with a 107Y XL service description. Load index 107 corresponds to a maximum load of 975 kg per tyre, while the Y speed rating allows speeds up to 300 km/h under the specified operating conditions.

The Ecsta PS71 EV is designed specifically with electric-vehicle applications in mind, combining high-speed stability, responsive steering, wet-road grip and durability for the higher loads commonly associated with EVs. The tyre's performance-oriented construction is intended to provide confident handling on dry and wet paved roads while supporting the demands of modern high-performance vehicles.

Tread Design and Steering Response

The directional tread design uses wide longitudinal grooves and performance-oriented tread blocks to support stable road contact and responsive steering. The tread configuration is engineered to provide precise handling feedback during lane changes, acceleration and cornering.

Dry-Road Handling and Cornering

The 255 mm footprint provides a broad contact area for dry-road grip and cornering stability, while the 50-series profile balances steering response with everyday road comfort. The 107Y XL specification provides increased load capability suitable for compatible high-performance vehicles and EV applications.

Wet-Road Performance

The tread incorporates wide grooves and multiple traction edges designed to evacuate water from the contact patch and maintain grip on wet roads. The tread compound is developed to support braking, cornering and steering control in changing wet-road conditions.

Electric Vehicle Performance

The Ecsta PS71 EV is designed for electric vehicles, where tyre performance can be influenced by higher vehicle weight and immediate electric-motor torque. Its construction is intended to provide stable handling and durability while maintaining the high-speed performance expected from a premium performance-oriented tyre.

Comfort and Road Noise

The tyre is engineered to balance performance with everyday driving refinement. Actual ride comfort and road noise depend on vehicle configuration, road surface, tyre pressure, suspension condition and driving conditions.

Seasonal Performance

The Kumho Ecsta PS71 EV is a summer performance tyre intended for paved-road use. It is not designed as a dedicated winter tyre, and winter or severe-snow performance should not be assumed unless the physical tyre carries the applicable winter markings.

Load Capacity and Speed Rating

The 107 load index corresponds to a maximum load of 975 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h, subject to the applicable load, inflation pressure and vehicle manufacturer's requirements.
