Hi, I just picked up a set of used 38" Ground Hawgs on rims for 75$.

Two of the four don't hold air. One will hold for a day or two, and one for a week (according to the seller).
I was wondering how I would go about popping the bead and reseating it with bead sealer, since they're too big to fit in any tire machines I have access to.

I've seen some kind of wedge looking things selling that I guess you just ram in between the bead and the rim with a hammer, anybody ever use these before and how good do they work?

Or any other method of breaking the bead on such large tires without a machine?

Might call up the local tire shops to see how much they'd charge me to fix the tires for me or even if they can due to their size, but would rather save myself the money if I can just do it myself.

Thanks

 

Surely someone has to have some kind of shop secret to fixing large tires without a machine. All I really need is to break the beads on them, give the rim a good clean to get any sand/mud that would be causing a leak out, and pop the bead back again. Think maybe just standing/jumping on the tire near the bead might work? Worth a try I guess... but I only weigh about 110lbs so not sure how good its gonna do
