I replaced my stock Continental tires that came on my '08 Altima with these tires. Wow, immediate difference in road noise reduction. My ears no longer rang on road trips. I no longer had hydroplane issues either. I drive quite a bit in the winter due to recreational skiing and teaching/patrolling on skis. I found traction to be quite good in all but the worst conditions.
Glare ice was the only condition that I had zero control in. Otherwise, hard pack traction was fine.
I have recommended these tires to other.
