Being a gas caddy I don’t think spraying the interior of the tire with flammable liquid and lighting it off is the way to go.  There might be more excitement generated than you would want.  I have used the ratcheting cargo strap method to expand the bead on my lawn tractor.  In fact I used two of the 1” straps, one on each side to pull the tire in.
