My gearmotor runs at 9RPM, and i need to turn my wheel at that same speed (or faster) so i have 2, 10" pulleys. Right now i'm using a belt that measures 25 1/2" outside pulley to outside pulley. Once plugged in, the motor pulley turns fine but the wheel pulley starts to turn then stops as the motor continues turning. If i put a smaller pulley on the wheel, will that work better or should i get a longer belt??

The pulleys are the same size so the ratio is 1:1. A bigger driver (motor side) than the driven side will make the driver spin faster and vise-versa.
The belt slippage problem is either belt tension or too much torque for the type of belt. If there is not a way to adjust belt tension or a way to modify current design consider a spring loaded tension arm. If it is torque belt selection might do or go to gear tooth belts and pulleys.

Sounds like you need a shorter belt if the motor pulley is turning and the gearmotor pulley is not.
The motor pulley is not tight enough on the belt.
You could try to put some belt dressing on the belt and see if that stops the slippage before buying a new belt.
Is the motor speed and the gearmotor input speed correctly matched?

Are you sure your belt is too tight? If the wheel does starts and stops, it sounds like the belt is too loose.
It would be cheaper to change the length of the belt than change the diameter of the pulley.

Belt length has nothing to do with your problem unless it is too long to prevent proper tensioning. Is the belt tensioned properly? Does the belt cross section match the pulleys? Is the belt cross section rated for the load?
