29x2.0 tires popping off 42mm rim

@DavidHood

One thing missing from this conversation is rim width. My KH29 came with a KH Freeride rim which is 47mm wide which really spreads out higher volume tires like the 2.4" Maxxis Ardent. Whereas the Kris Holm 29" XC Rim which is only 38mm wide would be much better suited to the 2" Schwalbe ‘big apple’ tire. I contemplated waiting for the release of the 29" Oracle which comes with the 42mm wide Nimbus 29" Dominator2 Rim. In the end, I want my 29er to be set up for off-road use hence my decision. I have a really nice (see auto sig) 36er for the road. I must admit, my KH Freeride rim and the 2.4" tire is not bad at all on the road. Then again, the whole kit is so much lighter than a geared 36er that you barely notice the knobs.

I’m a bit late to this conversation but having the road tire blow off my new 29" Oracle with the 42mm rim put me to searching the forums for help! When I ordered it I asked UDC to put the Big Apple 29x2.0 on for road riding. I have been very happy riding a Big Apple 26x2.35 on my 26" wheel so ordered one for the 29er. The new tire is rated up to 70psi, so I inflated to 65, and later that night I heard a loud bang (thought someone broke into the house!) which was the tube popping after the tire bead popped off the rim. I replaced the tube and slowly inflated to 40psi and I can see how the bead is getting pushed off the rim. I’ve read about this phenomenon in other threads (Tire options on KH-29).

My questions are: Will this be an issue with every 2.0" tire I put on my rim (such as the Marathon Supreme)? Will this happen (or be less likely to happen) if I get the 29x2.15 or the 29x2.35 Big Apple? I like to ride at higher pressures for speed/efficiency.
