Yep, they sound the same, and in Australia you’ll see both used, but what’s correct? Is it tire or tyre in Australia?
It’s a regional thing, and tire is the correct spelling in the US and Canada. In British English the correct spelling is tyre.
Australia is a long way from the US, Canada, and Great Britain, but whether we like it or not as Australians we should use tyre as the correct spelling of that rubber stuff which goes on our rims.
So there you have it, the correct answer is tyre is the correct spelling in Australia, and if you spell it as tire you’re incorrect.
That’s why Tyroola is spelt with a y. Otherwise it would be Tiroola, which looks a bit odd.
Hold on, is it spelt or spelled?
