Yeah, I see that someone 'ringing' someone matters because that's idiomatic and that should be right but why does it need to be spelled differently?

And I see where you're coming from because 'tire' looks awful to me, like someone can't spell (and I know it's correct for American English but it still looks bad to my eye - like all those 'ize's).

So I still don't know - I guess what I feel is I still don't see why the majority have to adapt because a minority can't?
