Build your own tire bead breaker?

Discussion in 'Mechanical & Technical' started by Mechanical Husbandry, Oct 16, 2009.

  1. Hey folks,
    I'm going to be attempting to build a tire bead breaker this weekend and I was hoping that someone may have some design ideas. I'm thinking of a 2 or 3 foot lever that mounts on a hinge at the base of a wall... It would resemble a giant, stationary nutcracker, with the wheel laid flat at the hinge. Some piece on the lever would push down on the sidewall, so you'd have all this leverage to break loose the bead. Anybody try something like this?
  2. I haven't built one, but I'd be interested in what you come up with...

    my last bead breaking method...well...sucked. and I'm gonna need new tires soon

    Jack your car up. Slide the M/C tire, disk side up under the cars tire and lower the car tire onto the bikes tire. Be carefull not to touch the brake disks(s)
  4. and for front wheels? pieces of 2x4 to keep the disc off the ground?

    this makes me happy.
  5. You might also put a 2x4 between the ground and the bike tire at the edge of the rim to keep the rim from getting damaged.
  6. You can do that, or just use a vice. Before I got my machine, Cobra525 and I just used his bench vise to get the bead to break. Once it's broken, it should be pretty easy to force the rest of the bead to separate from the wheel with just your palm.

    James idea is good too if you're careful. But if something goes wrong, you're going to regret it something aweful.
  7. Motorcycle kickstand, still attached to the bike. This, of course, assumes that the tire you are changing is from a different bike. Or, you could just buy the cheap bead breaker from Harbor Freight.
  8. Oh, good idea. But thinking about that just now...What happens with beads that are super stuck and only free themselves in a big shutter motion? I could see this going wrong really quick.

    pscook, have you tried this mode very often yourself? If so, if this how you do it all the time? Give us more feedback on your experience with this. Could actually help with guys on dirt bikes perhaps?

    Then go to the car method. With the 4x4's to protect the disk's
  10. I hear ya' James. No need for me tho. I actually have a tire machine at home. :thumbup:

    If I had to tho, I would rock the car/jack method most anytime. But even then, I'd rather go with the bench vise first. Just more control that way for me.

    btw folks, please be sure to take the valve stems out before you break the bead.
  11. lol.

    super lol.

    yup! I hear ya! I'm lucky our BMW club has its own machine and a couple of buddy's also have machine's.
  13. I'm sure you know what I'm talking about, when I say coming from us who have done a couple sets by hand and the hard way, it sure is simple as shit to get it done with a tire machine. Off the bike, I could do a set (if both valves are out) in about 15 minutes. Maybe less. (no airing up or balancing involved of course)

    It's like "woah"... ;)

    Even that said tho, with the tire machine, it still takes a bit of getting used to. Used to take me a good while when I first got it. But with every set I do, it gets easier and easier.
  14. another 'interesting' way was to support the rim and tire using a 2x4 (to keep rim and disc brake off the ground) then prop a 2x4 or 2x6 on top of the tire, just up to the edge of the rim. Have a buddy drive his car or truck up this 2x4, the weight pushes the 2x4 down, and presto, bead broken. For best results, do both sides, in a couple locations, for those stubborn tires. Done this a couple times now with good success.

    Also gone the vice or c-clamp route but that takes a lot more work. Interested to see where you get with the homemade unit, thought about doing the same thing next time I need to change. Or as someone said, jus get the $30-$40 one from harbor freight.
  15. Motherfuckeeng luv the last vid. :thumbup:
  16. I had to use my 600 Hurricane in a pinch one time, and it worked pretty well. I learned about this trick from a dirt bike guy, which should be easier because long travel suspension, long kickstand, etc. I purchased a Harbor Freight tire changer (with integrated bead breaker) for $50, then got the motorcycle attachment for another $50. Then I spent $230 on a No Mar bar, clamps, yellow thing and weld on adapters for the HF changer. No looking back, and no more $ out of pocket for tire changes. Actually get to use the tools this weekend to put new skins on the commuter.
  17. Awe, thanks. :thumbup:

    Yeah, with a dirt set-up, I could see how it'd be easier.
  18. I used to use a big C-clamp. It worked OK.
  19. I've used carb cleaner to seat the tires on lots of stuff in the past.

    Just spray some inside the tire and strike a match.


    Then fill the tire with correct psi.
