I’ve had a slow leak in my rear tire for a while (-20psi a day) so I decided to put in a new tube. roval alpinist clx rim, specialized turbo cotton 26mm tire. wheel off, tire off, tube out, a little air in the new tube, tube in. tire was pretty easy to get back on the rim with my bare hands. massaged it around, tube definitely down in the channel, put a bit of air, squished it around some more…. But every time I got it towards 40 or 50 psi at least one section of the tire would not be seated quite right, not tucked under the lip and clearly taller. deflate, try again. deflate, try again.

finally gave up and took it to the LBS, they looked at it, plugged in the compressor, POP POP it’s seated at 100psi.

I was leery of pumping it up that high when it wasn’t seated right, but I’m gathering that’s what you do to seat it, and as long as the tube isn’t pinched in there (it wasn’t) it’s safe to do so? so, next time I just wail on it with my floor pump?
