just got them mounted on the car and after 2 days, i have to say they are an improvement over the Michelins. For the record, I has Michelin Energy SV tires, not Pilot Sports.
The Kumhos seem to stick really well to the pavement in dry conditions. Road noise is less than the Michelins, but oddly i can *feel* the road more closely. The tires don't seem to absorb impact as well, which i actually like. i feel a bit more connected through the wheel and the pedals to what the pavement is acting like below me.
Supposed to get some rain this weekend to test them in the wet.
So far, pretty happy for $65 tires!
