Mine is 2003 G35 Sedan. Recently when I was driving fast (like on highway), the noise appears from the back tire of passenger side for me. The noise is like "de de de"(not de......). When the car is moving fast, the noise is appearing fast. When the car is moving slow, the noise is appearing slow. When the car is stopped, the noise is disappeared. I hope you can understand what I mean. Does anyone have similar problem?

Thanks for the help.

 

If it was "de de de de, da da da", I would say it was Sting in your tire.

 

You either have a rock, nail, or something stuck in your tire.
