I put the same tires on that you are looking at Continental Extreme Contact DSW 06.
I thought much better than the Hankooks.
Only thing I didn't like was the flat spotting over night when it was cold.
Drive a mile or so and the flat spot evened out and was smooth again
Reasons I went with that tire!
Drove to Denver and back east several times in winter months; work great in snow,
But not a replacement for good snow tires in snowy states.
I'd buy them again.
My new Genesis G90 has Continental Contiprocontact W series tires OEM on it from factory.
smoother from startup with no flat spotting but not sure about tread life and looks like snow is a no-no.
I no longer drive to Denver so don't think that is not a problem here in Arizona
Continental Extreme Contact DSW 06 would be hard to beat on the K900
