There is a method that I've heard about but never tried myself - but it's supposed to work. I think you have to use starting fluid - "ether".

With the tire mounted on the rim and with the bead of the tire not set. Now spray the ether / starting fluid and get the stuff inside the tire. I think you guys can already see where this is going.

Stand back from the tire, far back, - then with a cigarette lighter light a flame from the can of ether and direct the flame at the tire. The resulting explosion is supposed to set the bead of the tire.

Like I said, I have not tried this, but the method was related to me by a French Canadian diamond driller (these guys are slightly crazy but know their stuff)...lol. Suffice it too say - it's probably not very safe or easy on equipment. Might pay to have a fire extinguisher handy too. <img src="/forums/images/graemlins/zombie.gif" alt="" />
