Just because a mtn tire specs a certain max pressure, doesn't mean the rim can handle it.
New rims?
I figured air pressure was the force that causes such a split, but assumed significant wear from brake pads had to occur first. I'm putting an iffy wheel on my mountain bike right now to keep me rolling until I get new rims for both bikes. Based on your post, I'm going to inflate to the low end of the recommended psi range.
