Just had these mounted last week so very few miles; I have a bit of vibration over 60--nothing terrible--but the car definitely needs an alignment before I can say too much.
Overall I am pleased. I was concerned about poor steering response more than anything based on a few reviews, but with mostly highway driving, I think these tires are the ticket:
Few steering inputs required to keep it straight
Very good wet weather performance
Good dry traction
Good steering response
I'll add further reviews as the miles build; to this point I'd day this is the tire perfect for my driving needs.
