first off, you will have to remove the valve stem fitting, then the 90% angle brass fitting, then all the nuts holding the 2 halves together. this is best done with the rim on the truck aired down. this will hold the rim from turning. you WILL NOT beable to do this by hand unless you have a 3/4 impact. after you get the rim nuts REMOVED, raise the truck and remove the outer rim. this is best done with a pry bar and 2 pieces of 2x2 pine. place the pry bar near the lug nut wholes and pry the outer rim up. place the 2x2 between the outer rim and the inner rim. do this across the rim. now that you have the sections held apart, you can use the swing hammer to separate the bead. to get the back side separated, use 2 pieces of 4x4 12 inches long. place the face of the rim on it by flipping over the tire wheel combo and swing hammer the bead. use WD 40 or a soap solution to lube the tire. if you have any ? pm me and i will give you my # so you can call. good luck. p.s. when you go to put it all back together, you will need to make sure the grove in the run flat is lines up with the air inlet pipe. also you will need a 5 gallon bucket or similar item. place on the floor and drop the rim/tire over it. this will hold the rim off the ground so you can reseat the outer rim. if you dont do this, you WILL NOT get it remounted. have fun
