Re: Just realised I DO care about the US spelling, after-all
As a left-pondian, let me unequivocally state that in this instance we got it wrong. The vast majority of the definitions of "check" do not define it as a "cheque" and have nothing to do with a bank draft.
It's too late now but US English should have retained cheque. "I need to check on my check" is just too confusing.
OTOH, tyre is just silly.
