How tough is it to mount 12" wide tires on Super Bronc Rims (probably about 10" wide). OEM tires are 21 X 12 - 8 and would like something new in that size range. Read here and there that putting these on the rims will even bring tears to some tire shop "experts!" Secondly, I don't want to run the risk of tire shop damaging my rims. Maybe an ATV shop would be an option if I have to take them in? Also, what name brand tires might I want to shop for? Heard a few weird stories about some tires being "out of round" even brand new. I've done riding mower mounts and didn't cry like a baby but then again these are much smaller tires/smaller rims. I'm assuming that breaking and then re-setting the bead on wider rims might be a bit tougher though I can WD-40 the hell out of everything and "man-up" if I need to. The Marine Corps toughened me up many years ago and I survived the SE Asia War Games but I'm no longer as lean or as mean! Help me out with some opinions on how to proceed. I'm assumming too that hard rubber- vs - soft rubber might be a factor in how hard it is to get these puppies onto a rim? Thank you kindly in advance.
