Here's a sure fire method that Michael Olsen used to great success far too many times on their last trip. The usual disclaimer applies. If you use this method you do so at your own risk. (Don't try this at home kiddies!)

Please note that this tyre is firmly secured to the spare wheel mount on the trailer while executing this manouvre.

If you only have to re-seat one side of the tyre, use less gas then you would if reseting both. Remember that Butane is heavier than air and will pool in the bottom bottom of the tyre.

1. Take the can of butane out of your little camp cooker. Place the nozzle from a can of WD40 (flyspray can, anything) on the very top.

2. Take the valve out of the tyre but keep it and the 'supatool' handy at all times.

3. Brush a little soapy water around the bead of the tyre and make sure that the bead and rim is clear of any dirt and twigs etc.

4. With a packet of matches ready to strick and one out to light, spray the butane inside the tyre and then stand back, light the match and throw it. KEEP YOUR FINGERS AWAY from the bead.

5. Tyre will expand onto the rim due to the expanding vapour ignition. The tyre will suck the displaced air back through the valve. Allow it to do this then screw in the valve, attach your compressor and get it pumping.

One other piece of advice, if it does not go pop the first time, make sure the lit match that has fallen inside the tyre is out before you reapply the butane gas.

haha....! It's an easy method and works well.
