Butane question for <span class="highlight">Mick</span> <span class="highlight">O</span>

As always your videos and blogs are a good and informative read....thanks

Question is that if you are not towing and therefore no A frame to securely bolt the rim and tyre to be reseated...

then is the BANG so large that it needs to be secured?
Or done carefully lying flat out in the open supposdly safely away from other gear and people ("apart from the volunteer match thrower")....will it / does it shift much?
Or on reflection maybe done under the towbar tongue with a hydraulic jack holding it down?

talking Landcruiser size rim etc here

curious on these scenerios

Thanks
