You know I've actually seen someone do that before, but I'm still not entirely sure how that works.

i dont think thats wd40... its starting fluid

Um...dumb this down for me. How does it work?

the explosion acts like shooting air into the tire beading it onto the rim

yea they do that like in artic excursions because the tires have such low air pressure to go across the ice so they can gain traction... they often come off the rim and the explosion makes the air expand and push the tire back onto the rim, simple physics

I would thing starting fluid would be the best choice for that. I will have to keep it in mind!

I've done this a few times, you have to hit it with compressed air right away or the tire will collapse and melt the rubber. all it is, is just the explosive force forcing the bead back on

brake kleen works well too :nod:

Lol no.

The science behind this working has nothing to do with fire, heat, or any other way said above.

The flame creates a sudden low pressure vacuum next to the bead which makes an extreme suction. Since something has to fill that vacuum and the lip of the rim stops air from flowing in from the outside the tire is sucked onto the wheel.

Believe it or not its the same science behind why it farts smell worse in the shower.

no one said anything about fire or heat, they said explosion, and explosions create pressure

Yeah but its got nothing to do with air or explosive force pushing out is my point. Its actually the lack of pressure that make suction bringing the bead back to the seated position.

haha i use this trick all day long at work to bead up those little trailer tires and quad tires. works well. i use wheel cleaner though

that's pretty sweet. So how much air is put into the tire, or does it just seal the bead so you can fill it up?

just re-beads it

Someone else watched the Top Gear Polar special.
