I just got my spinners for my 16" wheels, mine came with deluxe wheels. How do I remove my old center caps and install my new ones?

 

They just pop on there. If you have the non-spinners on there now, you may need to pry under the edge with a screwdriver to work them loose. Be careful, they're just plastic and can be damaged easily. The spinners are easy to get on and off because you can get some leverage on the "arms". Actually they are TOO EASY To remove, there's already reports of the pony spinners getting stolen. There's a mod on one of the forums for installing PVC caps behind the spinners so that the wheel has to be removed to pull the spinner. The downside is you have to remove the wheels to install the PVC too :P
