If not try lubing it- take tyre off and rub something soap based around the tyre beads, something that will not harm the tyre and will dry off in a day or two, even plain water can help but not anything oil or grease based. Liquid hand soap is good.
Then pump up to max pressure, and if that does not work you can safely go up to +50% of max pressure temporarily.
Also the kevlar bead on folding tyres will stretch out a bit over a couple of removal/refit cycles which will help.
