Kumho 235 45 R18 98Y Ecsta Sport PS72 EV 2025

Kumho Tyres positions the Ecsta Sport PS72 as an ultra-high-performance tyre with a strong focus on dry traction, handling precision, braking and high-speed stability. The exact 235/45 R18 98Y XL specification is listed with an asymmetric tread, C rolling resistance, A wet grip and 72 dB external noise. The PS72 is also identified as EV-compatible, making this configuration suitable for vehicles where the additional requirements of electric powertrains need to be considered. 0

Steering Response and Cornering

The 45-series profile gives the tyre a relatively firm sidewall, helping reduce unnecessary flex when the driver turns into a corner or makes a quick lane change. Combined with the 235 mm tread width and asymmetric tread layout, this produces a more immediate steering response than a conventional comfort-oriented tyre.

The 98 load index allows up to 750 kg per tyre, while the Y speed rating is rated for speeds up to 300 km/h under the applicable conditions. The XL construction provides additional load-carrying capability and support, which is particularly useful on heavier performance cars and EVs.

Dry Road Performance

The Ecsta Sport PS72 was developed as a performance-focused tyre, with Kumho highlighting dry-road traction, steering performance and high-speed stability. Its asymmetric tread separates different parts of the contact patch according to their function, helping balance straight-line stability with cornering response. 1

On dry asphalt, the relatively low sidewall and broad footprint help the tyre feel controlled during acceleration, braking and directional changes. It is therefore better suited to drivers who value a connected steering feel rather than the softer response normally associated with touring tyres.

Wet-Road Grip

Wet performance is another important part of this specification. The exact 235/45 R18 98Y version carries an A wet-grip rating, while the tread is designed to maintain effective contact and evacuate water through its groove arrangement. The EU product data also lists 72 dB external rolling noise. 2

This makes the PS72 a useful choice for performance-oriented driving in changing summer conditions. Even with its strong wet rating, correct tyre pressure and adequate tread depth remain essential for maintaining braking and aquaplaning resistance during heavy rain.

EV Compatibility and Everyday Comfort

The PS72 is designed to accommodate modern performance vehicles, including EV applications. Electric vehicles can place additional demands on tyres because of their higher instantaneous torque and, in many cases, greater vehicle mass. The XL construction and performance-oriented casing help provide the structural support required by this type of vehicle.

At the same time, the 45-series sidewall is not intended to deliver the softest possible ride. Sharp road imperfections can be felt more clearly than with a taller-profile touring tyre. The 72 dB external noise rating gives the PS72 a balanced road character, while the EV-compatible version is also available with K-Silent technology in this size. 3

Who Should Choose the Ecsta Sport PS72 EV

The Kumho Ecsta Sport PS72 EV 235/45 R18 98Y is best suited to drivers of performance-oriented passenger cars and EVs who want responsive steering, strong wet grip and stable high-speed road manners from a summer tyre. It is designed primarily for paved roads and should not be treated as an all-season or winter tyre.

For customers using Dwbtyres and looking to buy car tyres in UAE, this specification is particularly relevant when the vehicle requires 235/45 R18 with a 98Y XL rating. The exact 2025 product listing identifies South Korea as the country of origin and 2025 as the production year. 4
