rattling noise

when i ride i get this rattling noise from my wheels at first it was only back but now its front too.. i have my bearings taped cuz i got my eagles ovalized too and that doesnt stop the rattling ..also i know for sure its not my brake what can it be?
 
my bolts are as tight as they will get shou ld i try different spacer ... also thought it was the spacers.. do skate bearing spacers work ?
