I was very reluctant to use these tires due to the lack of extensive reviews and tests, and the...........well, not the best around, reputation Kormoran have.
I haven't used them in snow or ice, so I cannot comment on these areas. Also, I cannot comment on the Handling section as defined here, because I didn't take them to their limit. In general though, their handling is pretty decent with a progressive feeling as you enter a turn with ever more speed.
They have done approximately 2000km on mostly wet surface and with temperatures averaging 7 degrees C.
Through heavy rainfall, with water at 2-3cm depth and speed at 70km/h, they just cut their way through like a knife on butter. No pulling, no insecurities whatsoever. Very impressed there.
I tried emergency braking from 90km/h to a complete stop on semi-wet surface. ABS did not engage, a praise to the traction of the tires in my opinion.
Their real con in wear I think. They were at 8.6mm on installation and after 2000km the fronts are down to 8.1 and the rears at 8.3mm. So, the rubber forecast isn't favourable.
I consider myself a normal-and-a-bit--spiritied kinda guy. With these things in mind, I found the tires very satisfying on both dry and wet surfaces, although I did not get the "What? Is that all you got?" provocation that PS3 used to give me in the past.......
For normal driving, I'd say there is nothing wrong with them. I also drove them to my car's max speed, 190km/h for 20km. No shaking, no weird instabilities or sounds. All ok here.
On consumption now, I get the same consumption, 4.6lt/100km, that I had with Energy Savers+ (but keep in mind that the latter have 63000km on their clock AND 5.4mm of tread!!!)
To sum up now: according to ME, the tires outperform their label F consumption, E wet, and 69db in both dry and wet surfaces for the average driver. I have no idea about their behaviour on snow and ice. Wear does not seem promising (although these are my first ever set of winter tires and I have no idea how long top ones last). Low price for them (180 euros an installed 4 set).
Would I buy them again? Yes, unless my biases beat the facts. I'll return with more info as I use them more.
