    I have no problem breaking the bead of my front tyre with a vice, but my 100mm vice at home is too small for the rear tyre... if I have to go out to break a bead I'll stop at the tyre shop rather than go to work for a bigger vice.

    I could make a lever type bead breaker - but as an apprentice we had a manual tyre machine, with a lever bead breaker. As a 16 year old I had to swing on this thing to break beads - that was over 40 years ago, and I'm still reluctant to go back there.

    My rear tire was shot too and had a spare used one with hopefully enough tread to wear out the front.
    Anyway, the past 2 out of three times I let a shop mount my tires, the first time they did great, 2nd time they scratch my painted rims, the 3rd time they ruined a bearing.

    So I'm doing it myself for now on.

    I mixed up a solution of bodywash, mineral oil and water, nothing precise. I also sprayed the bead with a penetrating oil and let it sat over night.

    I use the C-Clamp method to break the bead along with a Motion Pro Bead Popper. With the bead popped I sprayed the edges and tire with Pam non-stick spray and rubbed my mixture along with it. I used regular tire tools and didn't have any problem. Also used rim protectors from MP also.

    I stopped in at Harbor Freight and got me a balancing stand and saw a bead breaker there for $40. that looked pretty handy and have also been scouting some newer tire tools that are out there, check out Mojolever.

    With the wheel still on my GS I used two of these so I could replace a bad valve stem.

    Hello, as I am a fond believer in tubes. (yes that is my own dillusional thought process). I have found the best thing for breaking beads in the shop or on the side of a mountain is the best rest beak-brakr.

    I find if I use my kit tools in the shop it helps to sort out what works and what doesn't.

    (no affiliation to best rest, just a happy customer)

    Used the vice last night in peeling the tire off a wheelbarrow rim. Tube is rotten. Now to find a wheelbarrow tube. I got it apart with no other tools.

    I've used my bench vise to break a stubborn bead before. Clamped all the way down and the bead still didn't break. I then added a c clamp on either side of the vice and finally it came loose.

    To break the bead on ATV tires I've seen people use their truck or car; they would line up the tire of their car so it would impact as close to the ATV rim edge as possible. Then drive over it.

    I've done the driving on the bead method as well. I take a solid length of lumber and make a ramp on to the bead, which I then "skillfully" drive my truck up. I do this as a last resort. It has never failed. Apparently, no bead is a match for a 3/4 ton pickup.

    I use a similar method but I substitute the car with a the second step on a starcase, very dependable and easy take the tires off that way..

    I'm surprised no one has mentioned the kick stand bead breaker method.

    I've done this many times, although I sometimes use the C-clamp.

    If you have access to another bike, lay the wheel on the ground, put the kick stand foot down on the bead area, and lean the bike into it. Sometimes it takes more pressure than others, but it has always worked.

    I realize this requires another bike, tough if you're out by yourself, but great if you're riding with someone else, or in your garage with another bike.

    Because the plastic chisel is light, easy to pack, and has no bits to lose or break, I dedicated myself to this method early on. I use a hammer in the shop, or a nice rock on the trail. It takes practice, and you have to work your way around the rim a bit, but it even broke the bead on the 180mm rears on my old Tiger. The only time it failed me was breaking the rear bead on my neighbor's 15" cruiser tire. We had to resort to a vice and a wood block.

    Whatever method you choose, wedge, bead-brakr, 2x4, be proficient enough to do it road/trailside, when it counts. I don't carry a vise, 2x4, or c-clamp on my travels.
