Wide Rims new tyres re-seating beads

Hi David
Just put a rope around the centre tyre,tie it off with a reef not then put a long stick under the rope and twist.
Good luck

Hi David

Just yesterday I had my Coopers fitted back from 7 inch steels on to the 8inch GQ alloys and was sitting watching what my tyre man was doing. He would inflate the tyre with the normal compressed air and then he also had a container with a spout in which there was more compressed air. This he would put on the edge of the bead and release a small amount of high pressure air into the tyre and it would reseat immediately.

There is another way to the rope idea. That is, to place a small amount of lighter fluid(or unleaded petrol) around the bead of the tyre and then use a match or spark igniter. The explosion will suck the remaining air out of the tyre pulling it on the bead. A tad dangerous I admit but I have seen it work.

Dear Outnabout,
years ago our local tyre fitter had a soft rubber donut shaped ring about a foot or so diameter and 2" - 3" in cross section. To help seat a bead he would slip this over the rim so that it would fill the gap between the tyre and the rim. He would then pump up the tyre normally and this rubber ring would either pop off the rim as the tyre filled or he would take it off as it got close to seating the bead.

I now use a modified version. I went to a bicycle shop and bought a tube of 13-14'' diameter and use that. It works very well. Partially pump up the bicycle tube so it's about 2'', then slip it over the rim. You have to turn it inside out a bit to get the teat on the outside. With a little soapy water you can then pump up your tyre (I have used my Blue Tongue compressor). Put more air in the bicycle tube if you have to fill a bigger gap. Be careful that the tube doesn't get pinched as the bead seats. One bicycle tube will stretch over 13",14",15" and 16" rims. Rus.

I haven't used it on new tyres; what sort of gap are we talking? Could you put a tube in the bare tyre and pump it up for a day to help puff it out? Rus.

easy done , get some soapy water and put some on the inside tyre , then put the tyre on something either side to raise the center off the ground , then put your foot in the middle of the wheel and hammer the edge of the rim with a rubber malot. Just enough to make a seal. The turn the wheel the other way , connect your compressor ( make sure th evalve is out ) and pump air into it whilst aplying pressure to the center of the rim again.

Hi David,

Seen that problem with 265's on 8 inch wide rims a fair bit at Peake. Thats the main reason I liked the 7 inch on the farm truck and the Prados.

Nothing beats a big fast whoosh of air. I inflate one of my other tyres with about 80psi, and use a hose between that and the flat tyre. It works best if both valves are removed. I actually use a 3-way hose so I can top up with air from the pump as I go. I heard from somewhere that you can get a high-flow valve fitting from the tyre shops.

When out in the bush, we use plugs so we try to avoid the problem, and are not fixing tyres at beer o'clock :-))

You can always fit some Prado rims on the 80 :-))

Cheers

What I do is spray the rim with a lonoline based lubricant then place the wheel valve down on a 15" rim or 1" smaller than the repiar, walk around the tyre until the bead is on the safety ridge then carefuly turn the wheel over place it back on the smaller rim the bead will drop down enough to seal seal on the non valve side, then inflate it. you will be better of with a rush of air from a storage system like a gas bottle connected to your compressor. Good luck. Eric.

Try soapy water and lift the rim up and down while inflating it
has worked for me maybe, but not on the same size Tyre, but it will work.
Liquid works as a seal

Worth a try

Seen at a local mechanic a pressure vesser as used on a water pump with a 1 1/2 inch tap and a flattened piece of stainless as a nozzle, pressurize the vessel and turn on the tap.
Have heard of a motorbike tube being used.
reseated a truck tyre using heaps of patroleum jelly once

Forget the butane, petrol, gellignite, nitro etc etc., its SHELLITE that does the trick.

A guy was doing it in the Tibbooburra Caravan Park one evening when I pulled in.

The key point is REMOVE THE VALVE, then suirt a tad of Shellite inside the tyre, run a 'fuse' trail out and over tyre to a safe distance, light fuse and pretend you have just dropped a mortar down the tube.

Produces a lovely 'thump' thats audible to all and sundry

AND it works every time.

Also this dude wasn't any fingers or sporting singed eyebrows.

G'day David,

Just check with Darren, he used the butane gas to seal the bead on one of
the 16X8" rims while on Hay River. He certanly would know what is the
right amount :)
