I've popped beads with the hi-lift method, it works pretty well, but your simple tool is good idea, and I'll have to buy one just to give you credit for it.
Thanks Cruiserdrew!
The Hi-Lift jack method is certainly effective, but there are certain times that it will not work, for instance when you have shredded your sidewall.
In South Africa, many of our overland travellers (What you guys seem to call Expedition type people) take along a spare wheel - with a tyre and a spare tyre with no rim on the roof rack, basically to save weight.
If a tyre is so badly punctured or as can often happen destroyed, then you would fit the spare tyre after removing the shredded tyre.
The Hi-Lift Jack on its own is going to cause a lot of frustration if the tyre sidewall/carcass has been destroyed.
Some guys do carry two full spare wheels, but it's horses for courses.
Someone also mentioned that I might have overplayed the effort required by the other Bead Breakers on the market to de-bead a tyre, these being the Tyre-plier and the R&R Bead Breaker. Well I have tried them both and yes: I do believe in my product.
I must say that there is nothing to beat the size, cost, efficiency and efectiveness of the Bead Buster and it works work on even the most stubborn tyres and those with shredded sidewalls.
Anyway get one from EOP, give it a bash. It works. BTW it took second prize after Warns Power Winch at the SEMA show last year. That should be endorsement enough.
