I got mine done at Les Schwab when I went to radial Firestone T831s. I got the wheels and rims powder coated and they check to make sure they're safe. I stayed there when he was mounting them so I could learn how it was done and do one myself. Pretty much like what's been mentioned already. First check the tires to make sure there's no debris in them. Next just put the tube in and inflate it a little to get it to take shape, put in the flap, put lube on it, lower the tire on the wheel, start the ring and stomp it around to the other side and it will snap in place, cage it and inflate. Pretty easy if you're careful.
