How to inflate a tire using WD40

Boats,
That`s about the coolest thing I`ve ever seen! What with all the trouble I`ve had over the years trying to get race tires to take a bead-used WD to lube the bead before, but this guy took one step further. Love it! I`m gonna send that video to our tire specialist on the sprint car team.

Did this many times while drag racing back in the day. Except I used lighter fluid, same result. When you put a 8 inch wide tire on a 10 in wide rim it's about the only way to do it. I would say, If you are thinking of trying this don't use WD40, Petroleum breaks down Rubber. Were as lighter fluid evaporates completely.
