Carl,
If you are worried about sizing, I would call and ask.
As Flatheadyoungin wrote, all you really need is a bead breaker, and a set of tire irons. (I prefer the spoon shaped ends, which are much, much less likely to nick the bead.)
You break the bead with the bead breaker, or your 2x4, preferably nicely sanded 2x4, slip one or both irons under the bead, and pop a section of bead over. Then you leave one iron in place, and lever up another section of bead. I have seen little clips on some tire irons to help hold them in place while you are messing with the other one, and it sometimes helps to have a long one for levering the new section of bead up, and a short one for holding the bead up. Alot comes down to how tightly the bead matches the rim.
It is great grunt work, and as SnowRidge mentioned, Murphy's oil soap, or their tire lubricant, which looks suspiciously similar, and you are all set.
All of which begs the question about why you need to do this so often and whether the right sealant or tire pressure wouldn't be more productive in the long run...
I remember a bad set of tubed tires we had when I was kid. 17 flats in six weeks, only one of which was due to a nail like thorn- the rest were due to small cracks on the inside of the tire literally eating away at the tube. Let's just say it was ugly time period.
All the best,
Peter
Pony, are you referring to ernemats post? I looked at this tire changer, but was confused on tire dimensions. I thought my 24. 12. 12 tires would not fit, but maybe I am misreading the dimensions.
So, how hard is to use this thing? Clearly a nice hydraulic unit would be great, but I don't have that kind of money.
Also, can I get these bobcat style 8 ply tires off or just my 4 ply balloons....
Also, my PT... The rims are inset the full depth as they are duallies. The center part of the rim is not in the middle of the rim but on the very edge. Would that mean anything?
