I’d be the first to admit that the crew I travel with are pretty proficient at coaxing even the most recalcitrant of 4x4 tyres back onto rims following outback tyre repairs. Not all of these methods are mainstream or orthodox to say the least. As a general rule of thumb, the larger the tyre (and the more robust the construction), the more difficult the donut is to reseat. Naturally, when you encounter monster truck tyres, you’ve got to rethink the normal processes.

Here are seven techniques we used over a morning trying to reseat a couple of big Michelins on Larry’s Unimog truck. Naturally, the successful one was the method first contemplated but last tried, principally because of the violence involved. It did work and work well however, as with the use of all flammable liquids and naked flames, there is an element risk involved.

Butane, my personal favourite, wouldn’t work on a tyre of this size as we were unable to get sufficient concentration of the gas into tyre to allow ignition. We don’t endorse the techniques but it does give you an idea of methods tried and discounted. Use at your own risk.

(Next time we’re taking a bloody great “bead-bazooka”)






Now you know why blokes only group hug in dire circumstances!


Tyre reseating efforts with volatiles - the good, the bad & the potentially ugly!


Cheers Mick

Mick,i know you didn't have any,and not trying to be funny,but why not 1 or 2 kgs
of Murphys (rubber grease),and they now make a 7kg Bead bazooka.
Have successfully used rubber grease on large ag tyres before.Works good,and is
re-usable.
Regards Barry

Not my tyres Barry and I have not had much experience of larger diameter tyres (until now). Normally too busy reseating my own. Have seen one of the bead bazookas just recently and Larry has purchased one for future trips. These issues arose out of some unforeseen circumstances associated with the Mog's on-board air system. What's represented here are simply a matter of "get me going" alternatives based on what we had with us at the time. We will be a lot better prepared the next time (we were using detergent as a lubricant where needed).



Now that I'm going up to the big 315's I may just need one of those Bazookas myself ;-)

(He who has the most toys wins lol)

Yep, it was a morning we'd all wish we could have been doing something else like surfing the spinifex but time learnt learning things is never wasted.

I should add that this method guarantees a fringe and eyebrow trim lol.

;-)

Cheers mate,

Right or wrong you fixed the problem and as you say will get another fix.

Seeing you all have mastered the repair on a pup, do you reckon you could fix this for us. Boss is a little cranky.



Thanks for the video Mick.

RA. may your hair just go a gray naturally and never go black again.

Yeah I think we've got a patch for that. Holy hell, you best let us know the story to that large disaster. It looks like a very neat plug cutter has been at work. Ran over a verticle pipe end perhaps?

Micko,
you got it in one. A piece of pipe sticking out of the ground. Maybe this is why no one smokes pipes anymore. To expensive. LOL.

Well there's how we fix it. Go find that bloody pipe and knock out the plug. A bit (ok maybe a lot) of Maverick Bond and a lick of silicone around the inside and she's done. What do you reckon RA?

Not surprised the boss was cranky.
That's an amazing puncture in anyone's book.

If the boss was a bit cranky maybe someone could have suggested smoking a peace pipe.....lol



And then run before the boss tried inserting the offending pipe somewhere else....hehehe

i would have thought the petrol would perish the rubber (nylon) inside the tyres, if you put a patch in side it would eat away at the glue and patch, i would assume the "burn" would have got rid of most but as only the vapors burn, any residule would still be inside it and will stay as it cant evaporate ...
Just my thinking ??

It may well do. The secret is moderation in those regards. You don't put heaps in. Given expansion ability, a very small amount is required. I reckon we'd have been lucky to use 80 mils and this probably ensures that most of the fuel would have been burnt off. If it's sloshing around inside, you would be asking for trouble.

These tyres were not actually damaged or patched, they had deflated as a result of an issue in the self inflation and air system on the mog. Unfortunately they also slipped off the beads as well. I'd hate to be retrieving what was actually inside those tyres after we had finished...spinifex, sticks, cap from the butane can, john's wristwatch, the spare keys, a bandicoot!

Don't be silly mate, it's a Mercedes. The minute the smoke detector goes off, Mog HQ in Frankfurt is notified and they send out a water bomber. The great thing is, the vehicle is so technically advanced, when they retrieve the black-box from the charred wreckage, they can tell you what burnt first and how hot it was!

Gott im himmel, diese Jungs sind verrückt!

Does the water bomber also drop a few bottles of booze to drown the sorrow :))

Mick O, Look upon this as just another learning curve in the scheme of remote travel....lol

I would just love to travel around in a 'Mog' but --big tyres get big stakes...umm perhaps you should stay with your 285's....lol

Nonetheless, good video, good times and a good result............just love the group hug, and by the way who was on the bottom???? rotflmao

Somewhere down the bottom of that pile was a couple of Cowangie boys, Jaydub and those disembodied legs belong to his Gregoryship of NSW.

Good times indeed Michael. Time spent learning is never time wasted ;-)
