Question 3769
What does the word "tubeless" written on the sidewall of a tire indicate?
- That it is a tire suitable for fitting on a bus.
- That it is a tire designed to be mounted without an inner tube.
- That it is a tire suitable for use when the roadway has water on it.
Show answer and explanation
Correct answer: That it is a tire designed to be mounted without an inner tube.
“Tubeless” means “without an inner tube.” The air is not held in a rubber tube inside the tire, but sealed between the tire and a rim designed for that purpose. It does not mean the tire is suitable for rain or buses. In the image, the word is visible on the front tire’s sidewall.
