Kumho 255/40 R19 100Y Ecsta PS71 2025

The Kumho Ecsta PS71 in 255/40 R19 100Y is a summer ultra-high-performance tyre designed for drivers who want a responsive feel from a 19-inch wheel without moving into an extreme track-focused setup. The 255 mm width gives the tyre a broad contact area, while the 40-series sidewall keeps steering response relatively immediate and controlled. With a 100 load index, each tyre is rated for up to 800 kg, and the Y speed rating is suitable for speeds up to 300 km/h under the applicable conditions.

The construction is XL, giving this Kumho Tyres specification a reinforced structure suited to vehicles that place higher demands on the tyre. The 40-profile sidewall is low enough to support sharper turn-in and reduce excessive sidewall movement during cornering. The trade-off is that impacts from broken asphalt, sharp road edges and deep potholes can be felt more clearly than with a taller-profile tyre.

About Kumho Ecsta PS71 255/40 R19 100Y

The Ecsta PS71 uses an asymmetric tread layout developed around dry handling, wet-road grip and predictable high-speed behaviour. The tread has broad longitudinal grooves for water evacuation, while the outer shoulder area uses larger blocks to support the tyre when cornering. The inner tread area helps maintain contact with the road when conditions become wet. Kumho identifies the PS71 as an ultra-high-performance summer tyre with strong wet and dry handling and braking characteristics.

Steering Response and Cornering

In this 255/40 R19 configuration, the relatively wide tread and low sidewall work together to give the steering a direct character. Direction changes should feel controlled rather than delayed, particularly on dry roads. The reinforced XL construction also helps maintain the tyre's shape under cornering loads. This makes the PS71 appropriate for performance-oriented saloons, coupes and other passenger cars approved for this exact tyre size.

Wet Road Behaviour

Wet grip is one of the stronger documented characteristics of this size. The exact 255/40 R19 100Y version carries an A wet-grip rating in the European tyre label, with an external rolling-noise figure of 72 dB. Its asymmetric tread and main grooves are intended to move standing water away from the contact area, helping maintain traction during wet-weather braking and acceleration. It is still a summer tyre, so it should not be treated as a winter or cold-weather specialist.

Ride Comfort and Road Noise

The 40-series profile gives the PS71 a firmer road connection than a conventional touring tyre with a taller sidewall. On smooth highways this can feel composed and stable, but rough urban surfaces can transmit more impact through the suspension. The official European label places this size at 72 dB for external rolling noise, so it is not positioned as a low-noise touring tyre.

Who This Tyre Suits

This configuration makes sense for drivers who value steering precision, dry-road cornering and strong wet braking while retaining normal road usability. It is less suitable for someone whose main priority is maximum ride softness or high sidewall protection on poor roads. Before fitting, the vehicle manufacturer’s approved size, load index and speed rating should always be checked. For buyers comparing performance tyres for 19-inch applications, Dwbtyres can use this specification when looking to buy car tyres in UAE. The Kumho Ecsta PS71 is best understood as a road-focused UHP summer tyre rather than a comfort-first touring option.
