Kumho 235/45 R19 99Y Ecsta PS71 2025

The Kumho Ecsta PS71 EV in 245/45 R19 102W is a summer ultra-high-performance tyre developed specifically with electric vehicles in mind. Its 245 mm width provides a broad contact patch, while the 45-series profile gives a useful balance between steering control and everyday ride comfort. The 102 load index supports up to 850 kg per tyre, and the W speed rating is suitable for speeds up to 270 km/h under applicable conditions.

The XL construction reinforces the casing for higher load demands, which is particularly relevant to heavier EVs. The EV-specific version is designed around the characteristics of electric vehicles, where tyre load, efficiency, noise and instant torque can place different demands on the tread and casing. Kumho Tyres lists this exact 245/45 R19 specification as PS71 EV, rather than the standard PS71 version that uses a different 102Y specification in this size.

About Kumho Ecsta PS71 EV 245/45 R19 102W

The PS71 EV uses an asymmetric tread pattern with broad longitudinal grooves and separate inner and outer tread areas. The tread layout is intended to maintain stable contact during cornering while helping channel water away from the contact patch. For the exact 245/45 R19 102W XL EV specification, the European tyre label gives B fuel efficiency, B wet grip and 69 dB external rolling noise with an A noise class. These figures make this version particularly relevant to EV owners who need to balance performance with the additional efficiency and noise considerations of electric driving.

Steering and Road Behaviour

The 245 mm footprint and reinforced XL construction give the tyre a controlled road feel without using an excessively low sidewall. The 45-profile sidewall allows enough sidewall movement to provide some cushioning over ordinary road surfaces while still keeping steering response reasonably direct. Under cornering, the wider contact area helps the vehicle feel planted, making this specification suitable for performance-oriented electric cars and heavier passenger vehicles with an approved 19-inch fitment.

Wet Road Performance

The asymmetric tread uses longitudinal channels to help move water away from the contact patch. The exact PS71 EV 245/45 R19 102W carries a B wet-grip rating on the European label. This places the tyre in a balanced position for drivers who need dependable wet-road behaviour without giving up the handling characteristics expected from a performance summer tyre.

EV Efficiency and Noise

Electric vehicles make tyre rolling resistance and road noise more noticeable because there is no conventional engine sound covering much of the tyre noise. The PS71 EV is specifically marked for EV use, and this exact size carries a B rolling-resistance rating and 69 dB external rolling noise with an A noise class. The reinforced construction also accommodates the higher loads that can come with heavier electric vehicles.

Ride Comfort and Durability

The 45-series profile offers more impact absorption than a very low-profile performance tyre, although the XL construction still gives the tyre a firm and controlled character. Drivers using the car mainly on highways should find the configuration well suited to stable cruising, while urban roads with sharp potholes will naturally place greater demands on the sidewall and wheel. As with any performance summer tyre, tyre pressure and alignment are important for maintaining even wear.

Who Should Choose It

This specification is intended for drivers with an approved 245/45 R19 EV fitment who want a performance-oriented summer tyre with EV-specific construction, controlled steering and balanced wet-road performance. It is not the right choice for vehicles requiring a different load or speed rating, and it is not designed as a winter tyre. For customers using Dwbtyres when looking to buy car tyres in UAE, the Kumho Ecsta PS71 EV provides a road-focused combination of handling, load capability and EV-oriented efficiency.
