I've had my 05 STI for about 2 weeks now and I want to know if the tire/drivetraing noise I hear is normal. I'm getting what sounds like tire noise but I'm not sure. Most noticable at highway speeds, doesn't change pitch if I push the clutch in. Deifnitely speed related with a 'once per revolution' sort of sound. Hard to tell if it is coming from both ends. It seems to be from the rear but when you turn your head then it sounds like it is coming from both front & rear.
I'm used to tire noise on my previous car, an EVO, but that one used to be loud at low speeds then quiet down at high speeds. The STI is just the reverse.
