DIY C-Clamp Bead Breaker Tool

[Gorminrider]

Sounds great and I don't doubt you! But...maybe my tire irons are not shaped correctly...that might be the secret? Mine are cheap-steel, and I had to grind them down to make them work at all..but trying very similar iterations of what you describe they slip out, fly around the shop and running three in place is going to take practise...My BIG screwdriver Might be better in the middle which I didn't try..and, I'll have to hold the tire down because it lifts too.

Also, I'm looking at an old tire to practise on and these come off with a certain amount of tire rubber stuck to the rim. previous experience informs me these are much harder than replacing tires I've worn out ...say on for a mere 7 years...

Following are my detailed instructions for the easiest, fastest, safest way to break a bead on any motorcycle tire.
.................................................. .....The tire irons I prefer are sold under a few different names. The ones I have are marketed by Rocky Mountain ATV/MC under the Tusk name, and are extremely strong, smooth, and slim:

You mean I could have this job done with only three easy payments of $3.49? Sheesh! Probably wouldn't have pulled a muscle in my back either...

I still like 93Bandit's diy breaker though. There's just something very satisfying about successfully using a tool the you made.

That's the floor Jack method I mentioned in the OP. It didn't work for me. Also, that tool looks easier to use than mine. The only issue with mine is the end on the threaded rod flops around while using it, which makes it tricky to line up at first, but once its snug on the tire it works well.

Thank you for the kind words. Its definitely satisfying.

I actually tried the floor jack today and it worked-even on a table...even debeaded both sides though I had to set it up again. It does tends to jacknife as it's working which i don't remember it doing on the youtube video..lighter wheel I guess. I wrapped the strap around the axle. Tire is dated 1999.

That type works quite well. I've seen them with the handles being reduced to just a stub, and you use them by putting a length of pipe on them.
