I've been trying to set the beads on my spare 31x10.5x15 tires but not matter what I do they just won't seat. They are on 10 inch wheels but still, I didn't think they would be this hard. They are my spares and I won't be driving on them full time. I need to get them both done so I can mount my rear tires on my current wheels though. Any suggestions? I tried using 3 ratchet straps and it almost seemed to work. I even tried the starting fluid trick. I hope putting the rest of my 31x10.5's on my 7" wheels won't be this much of a PITA.
