There is one and only one reason for a wheel on the tongue jack, and that's if you have a lightweight trailer, so that if you have trouble lining up to hook up, you can manhandle the trailer tongue into line with the tow vehicle hitch rather than endlessly pulling the tow vehicle forward to try backing up again. For a trailer that's too big to manhandle that way, the wheel is worthless.
