Compared to native rubber, they are softer, quieter, and more comfortable, but they fall short in the same KontiPremiumKontakt 5. Because of the positive wear resistance ratings, I chose it over 5 konts. Good directional stability and handling on any surface; does not jitter when flying at 100 mph through decent puddles. Puddles are completely unaware of speeds up to 80 mph. It brakes perfectly; in a downpour, when braking all the way to the floor from a speed of 120 km/h on the highway in front of colliding vehicles, even the ABS failed to function. The braking is smooth and confident. well-absorbs joints and bumps. All of this is brand-new. Observe further. Definitely a good investment. Golden ratio.
