Definition
- Noun:
- An inflatable rubber tube that fits inside the casing of a pneumatic tire: An "inner tube" is a hollow, ring-shaped component made of flexible rubber. It is designed to be inflated with air and placed inside a tire to hold the air pressure, providing cushioning and shape to the tire.
Usage Examples
- Noun:
- I had to patch the puncture in my bicycle's inner tube.
- Before the era of tubeless tires, most cars used inner tubes.
- Make sure the inner tube is properly seated inside the tire before inflating it.
Advanced Usage
- Technical Context: In engineering or mechanics, "inner tube" specifically refers to the air-holding bladder within a clincher tire system, as opposed to a tubeless system where the tire and rim create an airtight seal without a separate tube.
- The mechanic explained that the vintage car's wheels require a specific type of inner tube.
Variants and Related Words
- Tubeless (adj): Describing a tire system that does not use a separate inner tube.
- Most modern cars are equipped with tubeless tires.
- Tire/Tyre (n): The outer rubber covering that surrounds the inner tube (or, in tubeless systems, holds the air directly).
