Repairing Front Tractor Rim

[roscoe erf]

Have you watched the video to the very end …..
WOW - I thought I knew a bit about wheels and tyres, but ……a potential 22 hour delayed reaction from heat being applied to a wheelnut…..

Go on, bore yourself and watch the whole 9 minutes and 50 seconds without skipping - it might just save a life.

no you've already bored me

“No Air” = Vacuum.
It would appear that in a pyrolysis situation then the matter of which the tyre is created begins a reaction which gasses off and creates the dangerously high levels of pressure (not air pressure) within the tyre.

Now being aware of this possibility I would certainly not recommend that heat be used around a complete tyre / rim assembly.

Each to their own and may Darwinism not prevail.

Well I managed to fix the rim, I used a hydraulic jack to get it most of the way up then just went at it with a big sledgehammer to get that final bit. It seems to hold air still without a tube in it. Thanks for all the advice.

Nice one ….

If a big hammer cant fix something, its unfixable.

Haha well said

Job's a good'un then.

If in doubt tw4t it . ha ha

you watch it and tell me what is causing the tyre to explode heated air thats trapped if there is no air or a way for it to escape at a rate that exceeds the expansion it won't explode the same as any pressure vessel

Let us know where to send the flowers...

When people say they exploded after breaking the bead, yes the tyre might be off the bead but is it off enough to let the air out. If not it would just take enough pressure to pop it back on the bead, then I can understand it exploding as the air has nowhere to go.

I altered the centre's on two tractor back wheels a few years ago, took the screw in valves out, plasma cut the middle out and welded the the new centres in. They will of been hot at times, and they never tried to inflate as the air could just come out the valve.

don't waste your breath mate these experts know everything they've watched a video

Seems that there are different ways to produce “carbon black” fillers and probably no practical way of determining the proportion of each within any particular tyre.
Some may be far safer than others regarding pyrolysis.

The Potential of Pyrolytic Biomass as a Sustainable Biofiller for Styrene-Butadiene Rubber

This chapter explains the significant potential of the pyrolytic biomass char for use as a sustainable carbon black replacement filler for rubber materials. The manufacture of rubber filler is not only energy-consuming, contributing significantly to global CO2 emissions, but uses nonrenewable...

A local lad, a new driver, came round a corner too fast and saw me with my old rear wheel steer Loadall, bounced off his nearside bank and crashed into my front wheel. My wheel looked very much like the OP's. His father called out the local ag tyre company. I had envisaged that he would take off the tyre and tube and get me to heat it up with the gas so that he could hammer it back into shape. He said that it shouldn't be heated. He belted it back cold with a sledge hammer. Given the age of the machine (1984) the result was perfectly respectable. The little hatchback was a write off, it was an old banger.

It was a tyre fitter of 30 years experience that warned me about it, after tracking down a slow puncture to a bad weld on a rim bolt lug.

My father did a whoopsie on the JD 6400 with frontloader we used to have and a frontrim looked similar. I don't remember if it was heated up or not but we beat the thing back in shape, the tubeless tyre sealed perfectly and the tractor did pretty heavy loaderwork, not had a problem until we sold it a good few years later.
