Brake Noise Or Tire Noise?

[01Y87]

I had the tire shop replace my Eagle GA's and turn the rotors. Now there is a noise. Its hard to describe but its like a whiney noise that changes pitch with car speed (low pitch noise at low speed, high pitch at higher speed). I do not notice this noise when cruising or without brakes applied. Now, the new tires have those little "hairy" thingys all over them so could those produce noise? I don't think the problem is the tires themselves and they are the same size as original. Could the problem be with the pads or calipers? I have heard some people have noise when putting new pads on till they get settled in and he did take out my outboard pad to show me the wear so he did have to re-assemble the pad and caliper. BTW, my brake pads are a little low....

Since the rotors were re-surfaced could it just be a temporary thing till they wear in?

is it like a hum like hum....hum....humm and then gets faster with your speed?

I have had new pads that did that for 15 -20 miles or so. It is not uncommon for them to make a little noise at first like you mentioned. I would take it back and have them check it out. I have had a bad bearing that sounded the same way as well. Hopefully it is just the pads settling in.

what brand designation of tire did you get (ie: goodyear eagle f1...etc.)??

those "hairy" things.....are mold flash... from the tire molds getting worn alowing the tread rubber and etc. to flow into crevaces during final cure...they can make noise if located on the sidewall or crown edge. if not... the tread pattern itself can "sing" ...but i have to know the brand of tire.

It is a Goodyear Eagle GA. And the hairy things were covering the entire tread surface as well as the edges. I have put about 100 miles on them so far and many of the ones on the actual tread surface have worn off but the noise persists.

Its a very odd noise....
