I usually find pumping it up way higher than you'd think, usually seats it with a satisfying click. If the max pressure is only 60 or so, you'd be fine to pump it up to 90 or something (just don't ride it like that) and then deflate once it's seated. Tyres are designed to withstand many more PSIs than the max stated, for edge cases, hitting pot holes etc.

I do this with new tyres too and leave it for a while, maybe overnight, to make sure the bastards all good and properly sealed.

For some reason I have it in my head that the components have to withstand twice the rated maximum without popping in a static test, although I'd try to solve the problem properly before using a rim/tyre combination which needs more than it's rated maximum to seat because it's going to be a pain to dismount if it's that tight.

yeah, riding with a very wonky front tyre was a bit foolhardy. i didn't go very far or very fast though.
so last night i took off the extra rim tape, lubed it up and tried again. it actually went on less of the bead like this than before. i decided to add some sealant which (unsurprisingly) had no effect so i went to bed in a bad mood.
then this morning i got a couple of medium-sized children to put some weight on the top of the tyre as i pumped it. this made the tyre mount in a few more spots but really not very much in total. i had a breather then started again (no kids this time) and, unbelievably, it snapped into place!
if i make it to any cx races in january then i'll probably want to switch the tyres which will be something to look forward to!
