If you can swap your good tires to the Budd wheels.
As crenwelge pointed out and as I suspected too you probably don't have a pilot on the hub to allow you to properly use the Motor Wheels any how.

You can buy the Budd wheel nuts new very reasonably, they're extremely common and often easier/better to replace with new than to clean up old ones.
