I know getting an oversized wheel and tire back into place is a beast, but as has been mentioned before you will need to be careful getting it off and even more careful getting the pully back on while its on the bike. I don't know how you got the wheel/tire compo on, but I went to Walmart and purchased an automotive scissor jack and place the tire in the cradle of the jack. With the tire on the jack I can raise the tire up very slowly and get the caliper and spacers in place than slide the axel in. I have no strain on me and it's a one man job.
