Kumho 295/35 R21 107Y Ecsta PS71 2024

The Kumho Ecsta PS71 SUV 295/35 R21 107Y is a high-performance summer tyre designed for powerful passenger cars and SUVs that require a wide footprint, high load capacity and strong high-speed capability. This exact 295/35 R21 specification combines a 295 mm section width with a low 35-series profile and 21-inch rim diameter. The 107Y rating allows a maximum load of 975 kg per tyre and a maximum speed classification of 300 km/h.

This configuration is listed as an XL reinforced tyre and is intended for vehicles where the manufacturer specifies this load and speed combination. Kumho's 2024 technical catalogue includes 295/35R21 107Y XL within the PS71 range, while tyre databases identify this particular size as an asymmetric summer pattern. The combination of a wide tread and low sidewall gives the tyre a more direct road connection than a conventional touring tyre, making the specification more relevant to performance-oriented applications.

Asymmetric tread and wet-road performance

The PS71 uses an asymmetric tread arrangement with four wide longitudinal grooves designed to evacuate water from the contact area. Kumho describes the pattern around wet braking, handling and high-speed stability. The exact 295/35 R21 version carries an EU wet-grip rating of A, with rolling resistance rated C and external rolling noise measured at 75 dB, classified B. These ratings indicate a strong wet-grip focus, while the low-profile construction is intended to maintain stability during faster directional changes.

Dry handling and steering response

The broad 295 mm footprint and 35-series sidewall are suited to drivers who value steering precision and cornering stability. The reinforced construction helps the tyre retain its shape under higher lateral loads, while the asymmetric tread uses different tread zones for handling and road contact. This does not make the tyre a track-specific product, but it gives the PS71 SUV a more performance-oriented character than a comfort-focused touring pattern.

Ride comfort and everyday use

A 21-inch wheel combined with a 35-profile sidewall naturally provides less sidewall cushioning than a taller tyre. On smooth highways this can contribute to a stable, controlled feel, while rough urban roads may feel firmer through the steering and suspension. The 75 dB external noise figure provides a useful comparison point, although actual cabin noise depends on the vehicle, road surface, alignment and tyre pressure. Drivers prioritising maximum softness may prefer a touring-oriented alternative.

Who should consider the 295/35 R21?

This size is most appropriate for a compatible SUV, 4x4 or high-performance passenger vehicle whose manufacturer specifies 295/35 R21 107Y XL. It suits drivers who regularly use highways and want strong wet grip with responsive handling. It is less suitable for off-road driving, winter conditions or buyers primarily seeking maximum mileage and soft ride comfort. The Y speed rating is substantial, but the vehicle manufacturer's recommended tyre specification must always take priority.

Practical choice for UAE roads

For Dwbtyres customers looking to buy car tyres in UAE, this specification is particularly relevant to powerful vehicles running large 21-inch wheels. In hot conditions, maintaining the correct cold tyre pressure and checking alignment regularly are important for preserving tread condition and handling consistency. Kumho's published PS71 information gives a UTQG of 320 A/A, but this rating should not be converted into a guaranteed mileage figure. The exact vehicle placard and approved fitment should be checked before purchase.
