I normally only buy Michelin or Yokohama tires, but I went out on a limb with these Bridgestones and I'm glad I did.
These tires are one of the best I've ever owned. They have excellent dry and wet traction as well as fantastic cornering and steering response. Driving a powerful rear wheel drive sedan, I can't break the tires loose when it's dry. Even when it's wet, they still grab the road.
I couldn't believe how well these tires corner. Taking an on ramp at 90mph and I felt nothing but in control. Highly recommended for spirited drivers.
They ride nice and the noise levels are above average. They are not as quiet as a lot of my other tires I've owned, but I'll take a little noise to have a secure feeling.
I can't speak for tread life since I've only done a little over 1,000 miles.
These are my summer tires only, so I can't comment on snow/ice traction.
Bottom line; if you're looking for a grippy tire with great handling, these are for you!
