I've never written a review for anything. Really! But I wanted to share my experience. When I bought the IS it had Eagle GT. After 20K on the GT, the noise was killing me. I read the reviews like your are doing right now. I'm NOT a Firestone fan by any means.
However, I decided to gamble on these tires. When I picked the car up I noticed a big difference in response right a way. I had to go to Ashville, NC right off the bat from Atlanta. Long story short, took the highway heading to NC in the rain and the ride was totally solid and responsive. So, I decided to head over to the Blue Ridge Parkway to catch some curves on my way up to really see what they could do. Again, stable with very little side wall roll when even taking curves at 75 mph. Tracked solid and straight with very little noise even on the Blue Ridge semi rough pavement. I've had more sticky performance tires. But, for the price and all season! Go for it!
