tires=tyres
pajamas=pyjamas
on vacation=on holiday
Also, I think the best example of walking the English/Am-glish line is the Harry Potter series. I heard that Scholastic went through the language to make it “universal” as possible but I don’t know if they kept the same text everywhere.
tennis shoes=trainers (though an athelete might also call them trainers)
BTW—My wife hates the term “panties”.
