There not hard to take apart if they havent been on alot of years. But you need a breakdown hammer to make it easyer. Remove the tubes valve core leting out all the air then put some luiqed soap on the tire around were it joins the rim. Then take the hammer and try driveing the wedge end between the rim and tire working around it till its broke down do the otherside then find the notch between the 2 rim halves insert a prybar and pry them apart. then use more soap on the tire and liner so the other side of the rim will slide off.I can do this in a short time but i have fixed my own truck tires for years and i have never owned a truck that didnt have some kind of a split rim or you could sell the tires and give the rims away with them.
