Relax there son.
I do know what a 'Mog Wheel looks like - I've handled them before. Again - I use ether. I've NEVER had one de-seat, NEVER. I've had one not seat beacuase I either didn't use enough fluid or I was too late with the flame. Maybe some have had that problem, I'm just trying to figure out why.
That "pop" you speak of was a flame up and not an explosion. You can see in the first attempt that it never seated. Don't get bent out of shape.
As an aside - try and not immediately attack a man's knowledge of his livelihood. It's somewhat immature and "common". Learn to take some advise and critique. (I'm "expert" enough to know that that was 3 or 4 bad attempts at that exercise and you or your boy were standing too damn close to a combustive process.)
If you'd read what I said you would see that I too use ether. The first time I did it though I used the spray that someone who does it for a living had just successfully used himself.
If it wasn't an explosion then why did the tyre seat? If it didn't seat then why did it take air normally (hissed air out of the valve only until the airline went on) until I let the airline off? How you can say you can see it didn't seat, when a) it did, b) you weren't there and c) in your comprehensive list so far in this thread of what you have seated, you have never actually done that size radial on those rims?
Having done that size tyre and wheel many times (but only them, so I won't presume to know anything about how any others go on), I know that they will fall straight off again unless you give it air within a few seconds. If I stood further away I wouldn't be able to get the air on quickly enough. Thank you for your concern though.
If you still insist that I'm not seating it or it wouldn't fall off, then there would be subsequent movement of the tyre toward the wheel rim as the tyre pressure rises, but there isn't. So, if you are correct, every time I've done it, and all the driving I've done on those tyres since, they must have been unseated all the time. The only thing you could accurately say is perhaps the tyre is too narrow for the rim, but both are a suitable match according to Merc.
Attacking? I'm strongly disagreeing with you, when telling me my experience is somehow wrong. So, thats my experience, take the advice, those tyres fall straight off those rims unless you act quickly.
Did you read that post? Do you know what the profile of a Unimog wheel looks like, to know where the spray is actually going? Obviously not. "Overland Expert"? If you say so
