Other forms: tired, tires, tiring
A tire is the black rubber ring around a wheel, filled with air. The part that actually touches the road.
This is the American spelling, and British English writes the same object as tyre, which is one of the neatest spelling divides in the language. Either way it comes with punctures, tread, pressure and the spare in the boot. There is a completely separate verb spelled the same in both countries, since to tire is to grow weary, and to tire of something is to lose interest in it.
1nountireThe rubber covering around a wheel.
“The front tire was flat again.”

Too few real examples of this word to estimate which sense is commonest.
Also accepted in games: tyre
To tire is to fail. Old English tēorian meant to cease or to give out quite as much as to grow weary, so tiring was about running out before it was about sleep.

Built from
From Middle English tiren. From Middle English tiren, tirien, teorien, from Old English tȳrian, tēorian (“to fail, cease, become weary, be tired, exhausted; tire, weary, exhaust”), of uncertain origin. Possibly from Proto-West Germanic teuʀōn (“to cease”), which is possibly from Proto-Indo-European dews- (“to fail, be behind, lag”). Compare Ancient Greek δεύομαι (“to lack”), Sanskrit दोष (“crime, fault, vice, deficiency”).
