After reading all the negative comments about excessive noise and terrible wet traction I was a bit aprehensive about these tires. Admittedly I have only 2,000 miles on the car but so far here are my observations:
Noise - They are no noisier than the Michelin's on the Infiniti M35x I traded in on the Optima. I do not find the road noise excessive in any way. The car is actually quieter than my wife's Infiniti EX35 riding on Michelin's. Thay may be more a function of the car than the tire but noise is not an issue.
Wet Traction - Had a mjor rainstorm yesterday and went out looking for puddles and standing water. Found plenty with no problems whatsoever. I cruised on the highway at 65-70 with no feeling of lack of control at all. Hit several large puddles at 45 mph on a back road with no evedence of hydroplaning at all.
Snow - Can't help you here. Haven't driven it in snow yet but I'd be surprised if they were as bad as several reviewers have stated.
Am I happy with the tires? So far - Yes. Would I buy them again - probably not as I really like Cooper Tires and I usually buy them as replacement when I need tires.
So any of you out there who have these tires on your car - don't fret. They should do just fine unless they are really terrible on snow, whcih I have not been able to evaluate yet.
