Your own placard is the authority. You will find it on the printed on the tyre sidewall, next to the pressure range. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tyre.
What changes on this bike
Brompton specs the e-Motiq Electric C Line with a 16in Schwalbe Marathon Racer, which its parts page lists as 35-349; the 349 bead is Brompton-specific and not the same as other 16in bikes.
Brompton marks the Marathon Racer as e-bike compatible and lists it for both the Mk1 and e-Motiq Electric C Line.
At 35 mm this is the narrowest tyre in this group; small, high-pressure tyres lose air faster in proportion, so the pressure printed on the sidewall wants checking more often than on a full-size bike.
