i have a set of stock steel 16.5's that i can't budge, i took them to the tire place i use, their machine wouldn't break the bead off the rim, next day i took them to a local place that does semi & tractor tires...the bead wouldn't budge, the machine ripped the sidewalls, but the bead still stuck! they laying out behind my shop w/tires still on the rim. guess i'm going to have to cut them w/something,..any ideas...they've been soaked w/oil, for couple weeks b4 i gave up and took them to the tire shop.
