Sealing tubeless tyres

Anyone got any bright ideas how to get a rear tractor tyre to seal on the rim? The tyres on okay, but just a paper thin gap in one or two places. Don’t really want to call out a fitter just to blow it up. Bear in mind that I only have a 100L compressor, perfectly okay for pumping up tyres, but not for giving a sudden rush of air.

As above, have done the lighter fluid trick a few times, never failed yet. First attempt ended with a little 'puff' and not much else as didn't put in enough lighter fluid, so don't be shy with it.
Obviously you'd need to fully break the bead again to get the fluid sprayed into the tyre.

I use propane from the oxy/propane set.
First time was desperation and it went on with so little drama, just small pumpff, no bang/thump /etc.
Just need to be quick with the airline after.
Sometimes set the valve at the bottom if tyre is on tractor and run gas through the hole with core screwed out, then light torch and direct it through valve core for a split second.

Much less spectacular than when the tyre guys use the cheetah tank.

Must admit it doesnt faze me now at all. Even super cautious dad went "oh that was simple"
Not for everybody I know and you certainly need to respect it but its got me going a few times now.
 
Give a almighty whack in the middle of the tread with a big sledgehammer while air is blowing in, possibly opposite side of the wheel from the leaking section. Also is the wheel on the tractor? Adjust the jack so the Tyre is just carrying a bit of weight.
 
Toilet paper. Wind it around between the rim and bead tuck it in then pour water around to make a temporary seal. It would be better to rest the rim on some bits of fence rail and push the tyre down so you have mainly the top side to attend to.
That’s if you can get any loo roll of course

Have tried the ratchet strap trick but that didn’t work, and have taken the core out, but I can’t get enough air in a short burst. Might have to try the lighter fuel trick, if I’ve got the nerve! How much do you need? The tyre is 16.9 /38.

What do you mean “seal”
(1)Seal to blow it onto the bead or “seal” (2) it once it’s on the bead ?
1
Core out valve / airline direct best , strap works but have to be careful. Better to use scrunched up length of silage wrap round the bead with plenty soap & unwrap once on the bead

2
Corroded bead sealer is excellent stuff for sealing up leaky beads

A good skoosh! Try a 5 second spray first time. If that’s not enough you’ll just get a little whumf and the tyre won’t go onto the bead. So next time do a 10 second spray... If you’re like me you won’t be brave enough to use enough stuff on the first go! :LOL:

Tyre off , wire wheel and clean rim bead spotless ,all rusty bits polished clean , red oxide , red oxide , paint ,and paint again , refit tyre with plenty of that black stuff that tyre boys use , blow up to 35 if you dare ,leave 24 hrs , ,

The rim is good just can’t get the bead to seat. I’m sure it will bang straight on if I can stop the air leaking out.
