Definitely take the wheels off and lay the wheels flat on the ground. Put both of your knees on the lower half of the trim ring and use the side of your hands to gently heave/bop them into place. Leave all jewelry off, especially wedding ring and wrist watch. I just did this with my NOS 14x7 Rally trim rings (real deep dish ones not the recent GM ones) and it worked well. The sides of my hands hurt for a week, though..."I feel yo pain" (In my best Bill Clinton accent)
