Except British English is spoken by, oh, I dunno, India, which easily outpaces the US by a factor of like 4.

And let's get down to it - both spellings are correct.

And if you must claim one to be "correct", then tyre wins by a huge margin, as it's the original form and I would assume a result of the French/Middle English amalgamation starting on 1066, so predating "tire" By some 700+ years.

So by age and number of speakers, "tyre* would handily be "more correct".

All this before even discussing the "synthetic" form created by Daniel Webster, whilst "tyre" would've developed organically. Let's not be prescriptivist.

In the end though, the greater import is there is no "correct" form - they're both correct, in context. If you can't handle that, maybe you should go back to school and take a linguistics class, along with some history, social skills, and respect for the cultures of others. That's usually called Kindergarten (or do you misspell this too?).
