Is tyring a word?
No, tyring isn’t a word. The confusion might arise because of the American English spelling of the noun tire referring to the rubber donut-shaped ring that is fitted to vehicle wheels (the British English spelling is “tyre”).
This is the same spelling as the verb “tire” meaning “make weary or become weary.” In this sense, “tire” is spelled the same in British English and American English. The correct present participle of this word is tiring.
