I'm about to pull the trigger on these. From previous posts I've learned that they run narrow. What I'm not sure about, is it the tread width that's narrow or the sections width? I'm already pushing it with a 255/40/17 on the stock 8" rims. I don't want to go to a 265 unless the section width runs narrower. I'm also concerned about noise. The TL is very sensitive to what tires are on it. My other choice would be the direzza star specs which I've heard were quiet and gripped very well. These are going to be daily driven but I'm getting them specifically for my upcoming trip to Willow. Any opinions??
