WD40 + lighter

Yep, the bush way of setting the bead!

Works better with ether BTW.

Kids: I'm a trained professional - don't try this at home!

Seen this before and did it to my wheel barrow tyre,,

I have actually done this successfully on a sport bike tyre once, but every other time I've tried it has not worked. Used starting fluid and it was a hair raising experience.

I have seen a ice-snow machine with bigole bubble tyres use this same method. I think the tyres were running at a ridiculously low pressure and the need to reset the bead was an ongoing affair. I would guess that WD would not have near enough of a flashpoint to create an explosion, or even flame up at all. If the tyre cools down prior to inflation, would not the cooling actually create a vacuum and suck the tyre back away?
I need some science here, and show me the math.

Couldn't believe it worked on my 180/17 Ninja tyre, it just made this popping sound and suddenly the beads were seated and I was glad my fingers were clear. Never got it to work again though.

"Did your eyebrows grew back? "
My bud had a job in our younger years delivering propane to people who lived out in the sticks. I would ride with him between jobs for the heck of it. He was in a ladys house for a long time on one delivery. I got cold sitting in the un heated delivery truck so I banged on the door to get let in. My bud and the lady both where looking inside the oven with the door open. When they got thru discussing the topic they both turned to face me. The lady had no eyebrows or eye lashes and her hair was frizzed.
The look was too much for me and I lost it laughing so hard I had to go back out in the un heated truck.

She did not see the humor.
