ratteling noise on my pro model

Hello,my pro model has this rattling noise when its moving. I never had it when it was new but once,after a trick I was doing which I forgotten, it had that rattling noise. Do you know what I mean by that noise?Whats that?How do I stop that?
 
I have locked my folding mech tight, once I took out the break for fun and the 2nd day I scoot,it had that sound.
If I tighten the wheels too tight,won't it spin super slow?
I had this problem before I got my headset.
