The Kumho Crugen HP91, specifically the 275/45R20 110Y model, is a dedicated summer performance tire engineered primarily for SUV-type vehicles. This tire features a generous 275mm tread width, a 45% aspect ratio, and is designed to fit 20-inch rims. With its ‘Y’ speed rating, the Kumho Crugen HP91 is certified to handle speeds up to 300 km/h (186 mph), making it suitable for drivers seeking spirited performance from their SUVs.
In terms of EU tire labeling, this model receives a ‘D’ rating for fuel efficiency and a commendable ‘B’ rating for wet grip. An important factor for both cabin comfort and overall efficiency, its rolling noise is classified as ‘B’, producing an initial sound level of 72 dB. Each tire weighs 17.22 kg (approximately 38 lbs) and boasts a reinforced construction for higher load capacity, ensuring durability and stability for heavier vehicles.
Wet Handling
The Kumho Crugen HP91 truly excels in wet conditions, demonstrating excellent resistance to hydroplaning. Its meticulously engineered tread pattern features both prominent longitudinal and transverse grooves. This intricate design ensures highly effective water drainage, swiftly evacuating water from beneath the contact patch. By minimizing water buildup between the tire and the road surface, the risk of aquaplaning is significantly reduced, enhancing safety and confidence in rainy weather.
Dry Performance
To bolster cornering stability, the Kumho Crugen HP91 incorporates robust, solid shoulder blocks, which provide a firm footprint during turns. Its strong overall tread profile contributes to a comfortable and stable ride across various road surfaces. However, it’s worth noting that in 2018 summer tire testing, this specific model was observed to exhibit less-than-optimal steering response on dry roads for its size class, which could be a consideration for drivers prioritizing sharp, immediate feedback.
