I've only driven 2,500 miles on these tires so far, but wanted to enter a review early and then revisit towards the end of tread life. During these 2,500 miles I've driven in several 2-3 snow events as well as a good foot of the white stuff. Absolutely amazing traction. The Michelin Harmony's these replaced (which had plenty of tread left) had me fearing for my life with any snow at all. I couldn't even climb the smallest of hills with them. The Continentals, however, have me feeling like my Altima is 4X4 Jeep.
I've also had the pleasure of driving in an absolute deluge of rainfall, and did not hydroplane or skid at all. Again, huge improvement from the Harmony's.
Cornering on dry pavement is awesome. Great grip, no squealing or skidding.
Finally, the ride comfort is unreal. They are neither stiff nor spongy. And I can't hear the tires at all at any speed, interstate or back road. Car feels brand new again.
I highly recommend these tires!
