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.
