Sorry to p everyone off with a request re tyre inflation but I can't find the thread which shows how to fast inflate a tyre using flammable materials.
Pls help.
Cheers.

Hullo John,
It was actually re-seating the bead. Is that what you meant or just inflating?
There are videos on Youtube that show it being done.

Yep, the flammable thing will reseat the bead but then you need to get a pretty hefty source of air pressure on to it before the air cools down. Compressor at the ready!
Never actually tried this myself but the videos I have seen show the guys reaching for the air hose quick smart after the kaboom..
Cheers

Actually, I think that's why Mick O said in his
blogs that you leave the valve out (install the valve stem, but unscrew the valve inner bits) - this allows the air pressure to equalise (without sucking the bead back off the rim!), then you can screw the valve back in and reinflate at your leisure.

Just chkd with my local 4WD tyre outlet. They don't recommend propane etc as it has blown out the tyre or damaged the wheel itself in their experience. They reckon that my little megagrunt compressor should be able to do it (reseat).
Up to now I've made do with plugs but after my NT
Gregory NP trip last month when I trashed 3 tyres on sidewalls I've got to upgrade to a real solution.
Will try the compressor on a tyre before making a commitment to purchase a tyre pliers kit ($365).
Cheers.

I have successfully reseated the bead on a 16" GU rim using my ARB Compressor (2002 vintage).
I use a long high volume hose and high flow fittings on the hose, including a shutoff fitting on the end. This allows me to attach either a blower to use cleaning filters etc or the tyre inflation valve which is on a short length of hose. I allow the compressor to reach the shut-off pressure in the reservoir which includes the hose. I connect the valve to the tyre before connecting it to the long hose and compressor. This allows maximum flow of air from the compressor to the tyre to
seat the bead. Coupled with liberal applications of dish-washing liquid it usually works.
I believe the increased air flow from the large volume hose is the key, this backed up with the compressor kicking in before the full rush of air is expired to back up the initial rush. Oh, and the dish-washing liquid.
The biggest problem is explaining to the wife where all the dish-washing liquid went.

If it is reseating the Bead that you are talking about then nothing, bar nothing beats/exceeds a tad of Shellite placed inside the subject tyre.
Run a 'drip line' up and over tyre, along the ground away from the tyre approx 2-3 m3ters or 4 if that makes you comfortable, drop to pne knee and ignite the aforementioned 'drip line' fuse and wait for it all to happen.
Remember - Removing Valve first is mandatory.
CAUTION/WARNING:
This is not the preferred method of completing the bead reseating procedure and I only use it nwhen all else fails.
Also the above procedure should only be used for/with a tyre that is off the vehicle and laying on the ground.
The northern Europeans use a method for when the tyre and wheel is still on the vehicle and because of low pressure/s the tyre bead has been rolled off into the rim.
This method consists of use a spray pack of flammable gas/liquid which the crazy mothers spray into the tyre via the space made by the rolled off bead, and then igniting same with a cigarrette lighter.
Appears to very effective, however they don't show how many fingers are missing or body bitz burnt off.

JB,
here is the blog in relation to the reseating using Butane gas.
Reaseating a tubeless tyre using Butane Gas
If you're looking at Tyre Plyers, definitely have a look at the R& R beadbreaker as an alternative. I used it quite a few times this year and found it an amazingly simple tool to use. I was also able to reseat the tyre with my bushranger compressor. You just need to ensure you have a good lot of goop around the beads (Soap paste made from lux flakes or similar).

Hey mate,
Is the decompression very bad like Muddy has said? ie. Have you had a bead break again because of decompression?
Cheers
Alan

No Al, I haven't actually had one come back off the bead. Because the sidewall is the thinnest piece of rubber on the whole tyre, it tends to soften and deform easily due to the heat generated by the expanding vapour explosion. As a result of ignition, the explosion causes expansion of the air outwards meaning a good deal of the volume has escaped the tyre in the brief moment in time before the bead grips. As the air rapidly cools, it pulls the already hot and soft sidewalls inward and could possibly drag the bead off the rim again. That's why I always have the compressor ready to go. I remove the valve centre mainly because there is a chance it could be blown out like a bullet.
In the words of good old Julius Sumner-Miller from the ABC in the 70's...."Why is it so?" LOL.
Cheers Mick

Thanks for that Mick,
I've never really thought about the explosion temperature as being a factor in the pressure increase, just the explosive force. Yes - Old Julius would have known the answer..
Cheers

Thanks Mick and others for these great responses.
Mick, re the tyre pliers and alternatives, that was going to be my next Q.
Does anyone else know of any other alternatives? A mate says that Malz sells a product (but couldn't recall the brand) which he thought might be superior to the pliers (but it might have been the R&R he was referring to).
Cheers.

Messing with fire you guys must be off your heads !!!!
Try a CO2 inflation devises, they work every time without guessing, will not kill you if you get it dose wrong. Then when the tyre is reseated you can inflate the tyre, all in speed & safety.
Good luck
Dave

Thanks Dave, but what do you mean by a 'CO2 inflation device' pls?
