use 2 tire removal tools(pry bars)...or smooth,rounded, large screwdrivers,lots of rubber lube, and a lot of patience.after you break loose the tire bead on the rim,take one pry bar and CAREFULLY pry the tire bead up over the rim(careful to not catch the tube) and leave the pry bar right where its at and take the second pry bar and do the same thing a few inches away from the first one WHILE you are making sure the tire bead on the opposite end is UNDER the rim seating area(giving you more room to walk the tire off) with your pry bars.remove tube.make sure the tube(stem) is in the right direction when reinstalling.to take the bottom bead off same as the top bead.
