78SUBURBAN: i've never seen one shaped like yours, but it looks like it would work. the idea is that the piece inside of that tool you have (it looks like the top of a screw) needs to fit down inside the valve stem such that the "valley" in that part of the tool fits over the piece inside the valve stem. I think you may be over thinking this. my suggestion is just go out and try it. you can't screw anything up on this.
I just spent an hour or two and how have both beads broken off of one wheel. I'm not sure that this tire will ever hold air again, becuase I've had to chisel around it and gouge it up with a screw driver. And the tire is STILL ON THE RIM!! How can I manage to pry this SOB from the wheel? I'm wanting to conquer this thing and not bring it to a tire store, but I'm about to loose all sanity. What am I doing wrong.. how can I get this tire to slip over the edge of the bead and off the wheel? The tire spoon just isn't wanting to wedge completely between the rim and the tire, even though the bead is broken off both sides. I really am going crazy, can somebody please clarify what I'm doing wrong?
......wonder if their machine will do ok with a tire that already has a broken bead? So its $15 to dismount and mount the tires?
(something about the guys that work there. its like they like a challenge. They've seen, done encountered it all, no tires gonna stop them type mentality) believe me walmart employees will drive you crazy enough with there nonsense
make sure to carry in the tires though to get that price otherewise they charge you for mount/ dimount on the vechicle.
