I was trying to seat my Geax TNT Saguaro onto my WTB i19 rim today. It had a stubborn dip in the bead and I couldn't work it out with my hands. I figured I would try to put 60 psi with a tube into it to try and get it to seat (I know, probably not the best technique). Well, at 60, it blew off the rim.
I inspected the tube and it had a long gash typical of a blowout. I've been running it for a few weeks, so I don't think it's defective. The tire bead looks completely normal and when I tried to mount again to asses the damage, it still required a plastic tire lever to get the final bit onto the rim.
One ting should add - I was using a 26 inch tube (gotta use them up, right ). I've been using them for a while now with 29" wheels with no problems. Not sure if this could have contributed to the blowoff.
My question is, do you think there might be a problem with the rim? And, given how the tire is still tight (its Geax TNT), would you consider it safe to run it tubeless? I know that if this occurs with a tubeless install it is not a good idea, but given that this might have come from the tube, might this be different (wishful thinking, perhaps)?
Thanks in advance!
