OK. Desperate times call for desperate measures. Can I get a step by step (or blow by blow
) guide? The theory sounds right, but how much and where. Do I blow it in thru the valve stem? Light it with a match? I might as well know the whole scheme and make my dicision.McDenny's

Hello all,
I was reading through and saw this thread and figured I might put my 2 cents in. I have changed allot of tires by hand (worked at a tire shop). Starting fluid and / or either works, but I wouldn't recommend it if you have never done it. It can cause a pretty big explosion and lift the tire several feet off the ground. I have done it but usually as a last resort. The blast can (looks like a propane bottle) works well, just blows a quick blast of air to inflate the tire, as stated before, you should remove your shrader(spelling?) valve when filling the tire for maximum are pressure going it. The straps work well as long as the tire isn't super cold. They sell a soap, I have always called it hardened Murphy's Oil Soap. Its like gold slime, we used it mount, dismount, and air up stubborn tires. You can actually lay this stuff around the bead and seal up the rim to the tire, as you put air into the tire, the tire raise and pushed the soap out of the way. Yes its messy, and yes it takes time to find the thin spots of hardened soap that keep blowing bubbles at you, but it works well. Dint use it in the rain, it is soap, makes lots and lots of bubble, especially on the side of the highway during a rain storm trying to change a semi tire. It is hard to have all this equipment if you don't do allot of tires, allot of the "tools" are expensive to have kicking around for one tire. I know its messy but we have actually used grease to air up a tire, layed a bead of grease around the tire where its meets the rim, (yup, takes allot!!!!) like we did with Murphy's, and air it up, messy, but works and gets you out of a bind
By the way, if you do decide to use either (starting fluid)
- Have your air hose ready with the chuck on it.
- Put the valve stem away from where you put your fuse of fluid (complete opposite where your going to light the "fuse")
- I use my foot and "walk" around the tire, pushing down, and spraying either in as I walk, NOT TO MUCH, you want either that sprays out like paint, not a steady stream
- As you have complete your journey around the tire and the two ends meet, make a line going off the tire onto the ground away from the tire. Some people like to use matches and throw them at the tire, I like a fuse myself. Now remember, you want to far away, but you still have to put air in this when it ignites
- Lite the fuse and in a matter of about 2 seconds it will either go boom, and you will hear air escaping from your valve stem, which means hurry up and install the air line so the bead doesn't fall, or it will just make a loud "hiss", which mean some of the either dried, or not enough.
- I am not responsible for what happens !!!!
Oh, don't try this more then 2 times before you let the tire "cool" the tire will get hot and soft and trying to blow it up several times in a row could cause the tire literally to blow up
Good Luck

I used to do the ether spray and pray method, but using a bead cheeter type tool is definitely the easiest way I have found. One other tip: Use a clip on type of air chuck, get some air blowing into the tire, then hit the dump valve on your bead cheater tool. When done right, the tire is on the rim, gaining pressure, before you figure out it is happening. I made my bead cheater out of an old 7 gallon air tank, and a 1-1/4 inch ball valve, and a short nipple(4"). Total out of pocket less than $100.00. Bead cheetah tool will cost you about $300.00 new, if you can't weld.

I'm surprised no one has mentioned bead sealer, the black rubberized liquid that you paint on a clean rim to prevent slow rim leaks. Get it at any automotive parts store. It doen't dry out like soap and will actually help to hold the tire on the rim when you are running low pressures( to a point)
We always used it on the 4X4s and ATV tires. It will also help to seal when you are trying to get the bead mounted.
I have always found that you are better using a coupla short crank straps instead of one long one so you can tighten up equally, just watch out cause when you break a 2" nylon strap it flies really quick and hard...
I've also used a chain and cable come-alongs...

Hey mighty dodge, I got a question for you. Did you weld the safety blow out valve on the bottom of the propane tank shut? I thought they would blow out at about 45lbs pressure. Just thought I'd ask, no animosity on my part, the rig looks similar to what I did with the old portable air tank.

Sorry for the delay. There was no safety valve on the bottom of the tank. As far as I know it was built in to the valve that I removed.

I've never seen one of these "cheetahs" in action... do you just shove the opening under the tire bead and let 'er rip - or is it attached to the valve? If shoved under the bead, how do you get it out of the way once the tire starts popping onto the rim?

When I use my home made cheetah I fill up the cheetah with 100lbs of air and let my compressor come up to full pressure. Then remove the valve stem core, put the air chuck on the valve so it's putting all the air it can through the valve stem. Put the cheetah nozzle between the rim and tire and open the ball valve. It hasn't failed me yet. The biggest tires I've done are my 16" truck tires.
