i ran a 39x18.5 bogger on a 16.5 rim with no safety bead, i got one bead off the rim. thought it was hopeless, got the tire back back on the rim using wrenches and screwdrivers but it wasnt even close to the bead, tried straps didnt come close. sprayed it with starting fluid and lit it and just kicked it once. it popped right on, i was pretty impressed.
