Title: tip for getting a tire off the bead
Post by verslagen1 on 09/12/08 at 17:25:13

Now that we know how to get a stubborn tire off in an unsafe manner (just fill it with 125 psi and it'll come right off in very small pieces)

Here's a tip from the BMW riders...

Very interesting. Turning that long board on edge and cutting a small bird's mouth where it crosses the upright board would double the strength of the pry board (to eliminate the cracking sounds) and keep the upright from slipping loose and breaking your leg.

Pressure treated lumber (at least in this neck of the woods) is all garbage like cottonwood. Very soft and weak. Spend your money on fir and larch, and I'll bet that widget will work like a charm.

It's a play on the lever - one of man's basic tools, and so dammed ingenious, I'm gonna build one to use for the Savage!!!

Thats the biggest Rube Golberg bead breaker I can imagine. Mine didnt want to let go, so, Naturally,

Pull the Shrader valve
block the whole thing off the ground with a 2X4 under the middle & whatever it takes to put on the sides to keep it stable, I dont tremember what I used.
Another 2X4, Long enough to deal with the pressure needed, mine was 8 feet long.
a short piece of 4X4, across the tire, just as close to the rim as possible & not catch on it.
The rope is only wrapped around & tied, so you can play with it & get the space between boards when it starts pressing hard on the tire. Its like a BIGGO nutcracker, with a 4X4 across the main "cracker" handle.

If it's so tuffa nut to crack, then, yea, stand the boards on edge, the lower one will require braces nailed to it to keep all the rasslin from knocking it over. If the rope isnt real stout, go around a few times. I started with not enough slack & had to re-do the rope, allowing the board ends to be further apart when the 4X4 was starting to press hard on the tire. No car should be needed, IMO.

This is all overly complicated. Go to Harbor Freight and buy a large "C" clamp, one big enough to get around the tire's body easily. Heck, buy two if you think you really need it. I have never needed more than one.

A "C" clamp has more than enough mechanical strength to break any motorcycle bead loose.

By far. I had the stuff in the garage & [popped that tire off the rim between a workbench & a car in a 15 X25 shop.+ I had the bike in there./ The description is more cumbersome than the doohickey. I even have a biggo C-Clamp, but I hate those things. Windy windy wind,, too harrd on my fingers & wrists. They are gtting pretty creaky & achy..

I went with a tire changer machine similar to the HF one, combined with a NoMar mount/demount bar. Breaking beads is simple with it; if one is careful there is no way you can scratch the rim, and actually getting the tires off of the rims is very easy.

The tricky part is mounting the new ones ;) Mind you, this is all for tubeless tires on my lil CBR, I've not had to use it yet on the S40's tires...

My 1500 suzuki front tire came loose just by putting my knees on it.

Changed both tires on my KLR650 recently and used a "C"clamp to break the bead. Three tire irons,Windex and talcum powder too.

I had my '81 GL1100 with me when I was stationed in South Korea back in the day.

Didn't have my bead-breaker there, so I took the scissor jack out of my Mazda, set it on the tire, then started to jack the car with it.

The beak broke easily. It worked pretty good.

YMMV!

The old bumper jack method is what my dad (and I used to do) used to break a car tire from the rim. Back in the day when there were such things as bumper jacks. He also would just drive one of the front tires up onto the flat tire to pop the bead. I think tires, cars and brain cells were different back then in the mid-50's though.

I guess since he's no longer on this plane it's safe to tell that he has, when stranded in the middle of nowhere, broken down the tire, patched the tube, re-mounted tire and tube and then blew it up with old fashioned lung power. Dedication to getting the job done. Did I mention we were on the extreme low end of the monetary food chain when I was a wee lad? But things got done.

As I've always said:

"Where there's a will there's a greedy relative".

did my rear tire recently,I put the whole thing in my vice, a few wooden shims between the jaws to bring the bead to the right level,
piece of cake.
