Huge wheels will require a gear reduction from any logical base vehicle. Those Cushman / golf cart wheels are about 4 feet around, that is every revolution moves the vehicle 4 feet. The big wheels may be 10 to 12 feet around. At the same rpm, you will go 3 - 4 times faster and have about 1/3 to 1/4 the pulling/pushing force. It may not move if too heavy and burn out electric motors or centrifugal clutches.
