High-Speed Stability and Braking

The 103Y service description combines a maximum load rating of 875 kg per tyre with a Y speed rating of up to 300 km/h under applicable conditions. The wide footprint and XL construction are intended to support stable road contact and controlled handling at highway speeds. Braking performance remains dependent on the vehicle, road surface, tyre condition, inflation pressure and driving conditions.

Comfort and Road Noise

Reduced road noise and comfortable operation are key characteristics of the Crugen HP71 EV. Kumho's EV-oriented design incorporates noise-reduction features and technologies intended to manage tread-generated sound. This can be particularly relevant in electric vehicles, where the quieter powertrain can make tyre and road noise more noticeable inside the cabin. :contentReference[oaicite:3]{index=3}
