Ok this is simple you spray some lube (WD-40, Honda Polish, cleaner, etc) around the inner metal part of the wheel exposed or soak all around the wheel in soapy water – something like liquid dish soap (this lets the tire sidewall slide over the wheel easy while it’s being inflated). Then you inflate the hell out of the damn thing and it will go BANG, pop back on the bead, and shoot soapy lube **** everywhere lol. That is what they do in the shops... We don’t give a **** about max PSI lol just inflate the ******* thing with a compressor tell it pops back on (use common sense though if it’s getting way to big). If it still won’t and it has a decent quantity of air in it take the tire/wheel with the air in it and throw it/bounce it around tell it pops back on. If you still have no luck take out the air and lube the **** out of it and try again.
