    I have my BMW tool kit with two tire changing tools ,but I cant even break the bead ?? The wheels are aluminum. Its a 1978 R100RS I heard you can lay the wheel down and drive a car onto the tire ,but I tried that on another bike once and nothing happened.. This has tube type tires ,not tubless.

    I'm presuming you have let the air out :evil

    Try using the side stand and the weight of the bike.

    I use big honking channel locks to break the bead. (rather I used to - now I take stuff in to a tire place)

    On the side of the road, use your sidestand as mentioned above. At home, for a really stubborn one, load it in a vice. (95% of the time just laying it on a curb and standing on it bouncing up and down a bit is enough to break it, but maybe I'm heavier than you)

    work it with a big vise is good or a couple of big c-clamps, if your not planning to reuse the tire. You could buy one of the bead breakers. I can usually stand on the tire with my heel on the edge near the rim and keep working on it. Put one heal near the rim edge and your foot to counter the weight at the rim edge.

    When I had to break the bead on a tire that had been on the wheel for 28 years I didn't so much drive a car over it as drop the car on it. Worked a treat.[​IMG]

    I assume you're at home..

    The bead can be broken with just two tire irons/spoons and some determination. And soap..

    Best I've come up with I read here I think.

    Plenty of soapy water sprayed on the rim/bead as you work. A warmed up tire might make it easier also.

    Take one lever and get it in there prying up against the rim. An inch or two away take the other lever and pry down. You may have better luck if you take a small block of wood and put it under the lever that's pressing the tire down.
    It will get you more leverage. I've used a wrench and maybe a deep socket under the lever before, but a block of wood works better. A 1" piece of 2x4 is about right.

    Basically you pry up with one lever stuck in there deep prying the bead down away from the rim while pushing down with the other lever, pushing the actual sidewall down at the same time. Hold pressure, spray soap, more pressure, then move over a bit and do it again.

    It's really a pain, but if you work at it, it will start to move. Figure about 10 minutes a side once you get the technique down. It's the hardest part of changing a tire.

    After you get both beads broke free, you then can get both beads to drop into the center of the rim while you pry the tire off the rim on the opposite side of the rim. I've read that a few zipties around the tire on one side can help.

    I haven't used it yet, but I recently bought a bead breaker from harbor freight.
    The safety beads on my motard rims have a tenacious death grip on the bead. I have no doubt that they would hold a flat tire on the rim for many miles if ridden slowly and transferring my lardness to the good tire.

    Your rim prolly has the same safety lip as this;

    If you want to change your own tyres, make/buy a bead breaker.
    The rear tyre seems to hang on very well, the front less so, from my experience. Seems that different brands are easier/harder to get off.
    A couple of longer tyre irons are good to have at home, but it pays to learn to use what is in the tool kit for roadside repairs.
    Those little air/Co2? bottles are great for pumping up a flat. 3 bottles will give about 32 psi.

    I made this bead breaker to take on the bike when touring into remote areas.

    What was that T shirt picture with the vultures? Patience my ass, I'm gonna kill something!

    I'm lucky-- I've been able to break the bead by just stepping it off.

    But didn't ADV Inmate "Martian" come up with a bead breaker a couple of years ago that required minimal parts and fabrication? I've looked, but haven't been able to find that post.

    Tires are harder nowadays to get off than they were many years ago simply because most tires are now tubeless and have stronger beads and stiffer sidewalls. I find that it works better to use a real ture lubricant (like Ru-Glide) and longer, 16" tire irons with the double-recurve ends (like Motion-Pro). And do your own tire changes to keep in practice.

    Like mentioned above, I found that using a hard-heeled boot and working/jumping could eventually break the bead... but that doesn't mean the tire is flexible enough to be pulled over the rim after that.....




    I had a tire that had been on, and full of air, for so long that I had to resort to this:

    ...course, you cannot re-use the tire..... :evil

    After I broke the bead with the weight of the car I did exactly that. The rubber was so hard after 28 years I didn't want to risk damaging the rim. Rubber and textile cuts easily enough but the bead wire was tough. Very neat, looks like you used a disc cutter ?

    I made a bead breaker and it works great, prior to this I would pay to have tubeless tires changed after a bad experience changing a K100 tire. Also get a gallon of tire mounting lube at Napa (about $15), makes removing and mounting tires much easier and works better than soapy water...

    I can't believe no one has said this yet, but make sure that after you break the bead, all the way around, make sure that the tire bead goes down into the valley of the rim, opposite the point where you are trying to lever the tire up over the rim. It's the only way you can get it up and over. Thankfully I've never had to do it on the side of the road, but in the shop I use several c-clamps to collapse the tire. Until I realized these couple of details, I had no success.

    Hello rom Germany, not the best explainer
    but i used a dupple latter, the v-form, i took the weel to the end, where the two latter parts are connected and with two peaces off wood, i could give enough pressure on the tyre.
    But sometime you need a hammer, means a second person ore take these straps,you take to secure load and keep the pressure on the ladder.

    I need to know how to do this road side. A learned skill that should be known. But I'm having the shop that ordered my new tire do it next week for $20. Mount, balance out the door. I've got to order a new front tire soon & will probably attempt myself.

    For roadside, or home, get some rim protectors otherwise things can get ugly quick.

    Pretty good explanation and a great idea to break the bead.

    Here in the UK, we take our wheels to a tyre depot (every town has one) and it's done professionally. In forty five years riding I've have never ever changed a tyre nor known anyone (perhaps trials riders do) to bother with it. It wasn't until I joined international motorcycle forum some years ago that I realised this wasn't the case in America.

    I have seen the sidestand method demonstrated at a Horizons Unlimited meeting and it was impressive. OK in emergencies. I carry a can of Tyreweld which works a treat. My last experience of a roadside puncture was on the way to Liverpool Docks to catch the Isle of Man ferry. Something as thick as an HB pencil pierced the rear tyre of my Pan and two plugs and two tiny gas cylinders failed to cure it. I rode for miles with almost no air in the tyre then finally dumped an aersol can of Tyreweld in and it lasted for days until I could get a new tyre fitted. Marvelous stuff!
