A bead breaker, the longest tar arns (read tire irons) you can get, and some washer solvent bottle plastic to guard the rim as you are leveraging, sweating, and cursing the tire off.

bead breaker

Unread postby usedcartech » 17 Jan 2008, 12:26

The last time I broke a bead on tubeless tire [auto] I used the cars bumper jack. A bumper jack had a metal foot made of flat steel .

I placed it next to the rim and applied pressure by jacking up the car.

back then they only weighted about 5-6000 lbs. so fo coarse the tire lost.

I have seen some info on the Magna V4 site that showes a guy useing a 5 gal plastic bucket to set the wheel on. the top was lined with old garden hose to cushion metal part of the wheel.

? How would you hold the Wheel steady to accomplish the task.

On bead breaking would the right size welders vicegrip work or am i dreaming?

Most shop type tire changers I have seen work use a curved shoe that pushes the bead against the other side of the wheel which goes up against a hard rubber block.

On takeing off the bead I saw a tool that would clamp to the rim [plastic feet?] to act as a stop so you start the bead off without the other end following

What's a good source some of this stuff?

And than there is BALANCING ?

That sounds like it might work if the bucket's not too big.

It's worked for me in the past on Buddy wheels.

Harbor Freight sells a tire changer thingy with a motorcycle attachment thingy but I'd be afraid to use it on aluminum wheels.

Tubeless is the same as with a tube, but a lot more work.

1) place wheel on suitable support
2) remove the valve stem and release all of the air
3) remove the valve stem lock nut
4) break the bead. If you are a big fellow, you can just bear down on most tires to pop them loose, flip the tire over and break the opposite side as well
5) insert the rim protectors
6) insert the tire irons and pry the bead up and over the rim. Most tire manuals recommend starting at, or close to the valve stem and working your way around the bead (using 2 irons-one in each hand)
7) the other bead can now be forced over the rim. It may be helpful to use a tire iron to work the edge over the rim, especially if the tire sidewall is a little stiff. Inspect the rim and use a wire brush to remove any corrosion.
8) lube the tire. paying careful attention to use directional arrow, force the first bead down over the rim
9) force the bead into place
10) at some point during the installation of the tire, you'll probably need to use the tire irons. As with tire removal, start at the valve stem and work your way around the rim
11) MAKE SURE THE TIRE BALANCE MARK ALIGNS WITH THE VALVE STEM, THEN INFLATE THE TIRE TO THE CORRECT PRESSURE
12) check the bead indicator, it should be equidistant from the rim all the way around the wheel
13) let the tire sit for a few minutes and recheck the pressure
14) if the tire is directional, there will be an arrow molded into the sidewall indicating the direction of the rotation
I love getting technical information to scooterists!
