can you please tell us which tires your car has? I've asked once already. Like I said before, I had an SRT-4 which came with BF Goodrich KD/W2 tires, and not long after I got that car those sonsabitching tires were the noisiest things I'd ever heard.

 

Everything on my car is stock including the tires(perilli nero zero). So i went to the dealer with this problem even though i shouldnt. This dealer is the first dealer that i mentioned ealier in post that scratched my paint.They said the noise were normal and mustang are noisy cars to begin with. They did rotate tire but instead front to back they did front side to side.........When i got car back the noise is still present above 40mph.I really dont have time to take it to another incompetent dealer espcially when i have to work 11 hours a day and can only do so on my day off. So no 13' Gt owners out there with same noise? I heard a few on youtube watching peoples self recorded cruising videos. Im starting to think its normal since i have no other signs of driving problems.

 

ISTR after a while the P Zero Neros on my 2010 got noisy after a while. I think the (same) tires on my '12 are starting to, but it's been a while since I drove the car and since it's barfing snow outside I'm not going to right now. plus the drone of the Flowmasters tends to mask a lot of other noises.

 

I couldn't really hear anything unusual in the video, but if it is a wheel bearing it will get worse to the point of obviousness pretty quickly.

One thing you can do is elevate the suspect wheel or wheels and try rocking them in and out a little. There should be no play. If there is, it's a pretty simple matter to adjust it out by tightening the axle nut just enough to eliminate the play.
