Home Made Bead Breaker First, let me say it is not my intention to detract from the tire-changing equipment designed and sold by "NYZTYZ". Although, I must admit with a name like that, you have to wonder! :-) However, some of us like to make our own stuff, some of us find that fun. Not to mention cost-effective. Following is what I use, and it works extremely well. I got the idea off someone's website some years ago. It helps to have a garage or shed with exposed beams. First you gotta find a piece of 2X4 lumber about 24 inches long. On one end cut out a piece to make a notch 1 1/2 inch wide and about 1 inch deep. The other end, bevel it a little so that it comes to a flat "point" about 2 inches wide. This will be the part that eventually comes in contact with the tire right next to the rim, and will press down to break the bead. Being rather soft wood, it can't scratch anything. Next, find another piece of 2X4 about 3 to 4 feet long, it isn't real important. It will be used as the fulcrum to push down the bead-breaking "point" described above. You drill a 1/4 inch hole through one end, a similar hole through a convenient wall 2X4 stud, and use a 4-inch long 1/4 inch bolt and nut to secure the fulcrum. You will cut a 1 1/2 inch wide notch about 1 inch deep to match the one you cut in the first piece, and in use they will lock together to prevent them from slipping as you put downward force to break the bead. Two more things to do -- figure out how high to drill the hole in the stud, and how far out to put notch in the fulcrum. To do this put down a piece of scrap 2X4 or 2X6 wood next to the wall where the stud is. Put a second piece parallel to the first, just far enough apart to let the brake disk fit between them, but to support the rims on both sides by the wood. This is how you prevent disk bending or scratching when doing the bead-breaking. Now, with the first piece of wood on the edge of the tire, put the fulcrum in place, into the notch (the fulcrum isn't notched yet) and move both around until you get the proper spacings. Remember, when you notch the fulcrum, it will sit about an inch lower, so take that into consideration when deciding how high to put the 1/4 inch hole in the stud. However, the smarter among you will realize drilling 1/4 inch holes is pretty easy, so it is easiest to drill 3 or 5 holes in the stud, the one you think is perfect, and one or two an inch or two above and below that perfect hole. Then it will be easy to move the bolted point up or down for the best compromise. Mark the fulcrum and cut the notch. Now, you are ready to break beads!! You'll have so much fun, you'll probably ask all your neighbors to break they beads too! :-) With the tire in place on the two scrap boards, and the center of the air valve stem removed, place the bead breaking end of the first piece of wood onto the edge of the tire, next to the rim, swing the fulcrum in place and lock the two notches together, and put your weight onto the far end of the fulcrum. Easy as can be. It does take a few minutes to put everything together for the first time, but once you have it subsequent bead breakings are easy and quick. The only disadvantage, it isn't portable.
