I purchased this car with OEM Bridgestone summer hi-per tires that were worn out, it was very noisy inside, rough/hard ride, and it tramlined on pavement changes. The seller warned me not to begin winter on these tires. I researched Tire Rack and this new design had the properties I was looking for. I was a little worried as I read some owner feedback about sluggish turn-in and don't expect a summer UHP tire's performance. After putting a set of 4 on the STI, I couldn't be happier! My car was transformed, dramatic lowering of cabin noise, my wife now wants to go in the STI now, vs it's too loud to talk from before. Just the quiet cabin would have been plenty, but now the comfort level is also much improved. The car no longer transmits every pebble, bump, imperfection to the driver, now it smooths over the small things, and lessens the pothole impacts. I no longer increase grip pressure on the steering wheel when I encounter a seam in the road, the tires don't tramline and sail over joint in the road without diverting their line. The Hankook's have been great in rain, slush, and 4 of snow, traction and stopping are first rate. They aren't much help on ice, but only a studded tire will help on ice? I am extremely satisfied with the Ventus S1 Noble 2 tires, they have made my STI a joy to drive in everyday use.
