Willie,
You don't pry the bead of a 7.50 tire over the flange. You gotta split the rim. Then the tire and tube slides off (Ha!!) the rest of the wheel. The beads on tube type tires are like an inch or more thick! That be the design.
The raised band that is off center on the rim needs to be worked one way or another I suppose. I was just wondering. Not hurting anything sitting there deflated (I hope!).
Check out this pic of me beginning to press an old 7.50 off of one of my old rims. The flange is off on the other side, of course, which will allow the tire and tube to slide off unobstructed except for the crud and scale (rust) that develops over time. Tons of fun, but I learned a lot. I was eventually able to get six apart, clean em up, paint em, and get the new rubber on. I have one more correct wheel that I still have to work the tire off of. It's worse than the rest. Maybe the wheel's unusable. Plus I've got that RH1 that I've gotta render.
