Wheel
noun
What part of your car are car rings? The wheels, of course!
But 車輪 isn't just for cars! You'll spot this word rolling along with bicycles, motorcycles, carts, strollers, trolleys… you name it. It has a slightly formal or technical tone, so in everyday talk, you'll more often hear タイヤ (tire) when talking about vehicle wheels.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
