I need to know if the noise that's coming from the front is the tires, or something else. It's definitely a tire noise, but it goes away when I turn the wheel to the right, so I don't quite know for sure that the tire itself is making the noise. They are brand new Perelli tires. I had bought an off brand, and they made the same noise, so I went back to Discount Tire and had them put the Perelli's on, and the noise is still there.

have you checked your wheel bearings? i would check the right front first.

Did you have any luck with this problem? I'm in the same situation. I bought an off brand set of tires as well, although I don't think this is causing the noise. It's definitly coming from the left, front tire and it sounds like a mud tire on the pavement going down the road. It makes the car "buzz" so much that the wood trim on my dash is starting to pop off! It almost sounds like you're driving on the rumble strips on the side of the highway (not quite that bad, maybe mini-rumble strips). I believe the noise started and continually got worse as the guide rod / lower control arm bushing began to deteriorate and eventually fell out. At first I assumed that this threw the alignment of the front/left tire off enough so it wasn't running straight and therefore was noisy. Well, I finally replaced the guide rod bushing yesterday and the noise is just as bad. If I brake hard, or turn left (not right though), the noise goes away. The new bushing joint should be pretty solid now, so I can't believe that the control arm is shifting forward and backwards anymore (like it did with the bad bushing when I braked or turned, which I thought might cause the tire to "temporarily" align itself and maybe make the noise go away). Would a bad bearing cause this (the wheel felt tight, although I'll have to double check later)? Could my grenaded guide rod bushing have put too much stress on the wheel bearing and caused it to fail? My gut feeling is an alignment won't necessarily solve this. I've just never known a bad bearing to make this noise before. Perhaps it's just a "bad" tire?

Both of you need to repack/replace your wheel bearings.

You replaced the front tires and the noise is still there so it has to be the tires????

Probably not the tires then, eh?

this is an old subject and most everyone has gone thru it. from what u said, it is most likely the front wheel bearings.

I went thru the same thing this summer. (i have pirellis too). I thought it was my tires too cuz it really does sound like a tire noise. the noise pitch will change if you turn wheel to left and to right at low speed. go to an empty parking lot and try it.

another way to chk is to remove wheel and open hub. loosen and retighten nut holding outer bearing. put parts back and test drive. chances are it will change sound or even disappear (but will most likely come back later).

thats how i confirmed mine. there are many threads here that talks about this topic. just do search. bearings are fairly cheap.

Yup, def. too loud to be the tires at this point. I originally suspected the wheel bearing when I heard the noise, but when I realised that the guide rod bushing was gone I figured the alignment was way off and the noise was from the tire not going down the road straight. It did really sound like a tire/pavement noise at first. As I was driving home, I was thinking that maybe if the noise stops when you turn left or right depends on if the inner or outer bearing is shot since turning might put different pressure on each bearing.
