You usually can reset the bead without removing the wheel from the vehicle. Jack up your vehicle and wipe away any dirt from the inside of the rim. Attach a compressor and begin airing up. Reach around the back of the tire and grab rubber. (You may need a buddy to help with this.) Pull the tire toward you so it can start holding air. Keep pulling and holding until the bead resets.
You don’t need a big blast of air to do this. A little ARB compressor, pumping out about 1.27 CFM, is sufficient. Be patient. This will take time, but eventually you will hear the bead pop into place. (Make sure no one’s fingers are in the way!) Lower the vehicle and put away your tools.
