Greetings from Oakland, CA.
Presuming you took a tire off, it must be possible. Is the wheel true in all directions? I guess you have tried obscene amounts of lube on both tire and rim. Is there rust or anything on the rim? Not that it should matter here but are you installing a new tube as well? It¡¯s a good idea.
That¡¯s all I have. Good luck.
