Need Good Wheels & Bearings

Hi:
We are designing a roller coaster car that will ride on skateboard wheels. Easy question. Not worried about traction & want hard long lasting wheels with easy rolling bearings. Any advice would be appreciated.

I found a LOT of information here on bearings. Not wheels though so I still need information on wheels.
