Tire Bead Blaster

Finally bought a tire bead blaster, or as I'd aptly call a tire "cannon", as it goes off like a shotgun! Even has some recoil!
Been thinking of getting one for years and should have years ago, but having trouble getting a new tire to seat a few weeks ago, I finally ordered one. I got a 2.3 gallon with trigger release, and when you pull that trigger, it dumps the air INSTANTLY! Today I used it for the first time and I was extremely happy I had purchased it! Any if you guys that change your own tires, even just a couple per year ought buy one....it's that good
Was changing a tire on my 16' trailer 15" wheels and the bead liked a little over an inch getting to bead of the rim. Put air hose on valve stem then pulled the trigger, and BAM, it was sealed and airing up.
Forgot to add....just $65 to my door. Best tool purchase I've made in years!

I have something like that at work, they call it a "cheetah"

I've used them. Work well..There's also rings that gets laid on the tire/rim that sorta does the same thing but are more dependent on the size of rim.. Not as much pucker factor in my opinion.
Also used ether in my younger and somewhat dumber days. It works too but a bit more scary...wouldn't do it today...
