Học thuậtThân thiện
Definition
Noun: A tire iron is a hand tool, typically a metal lever, designed for the specific task of removing and installing the outer casing (the tire) from the metal rim of a wheel. It is used to pry the stiff bead of a tire over the edge of the wheel rim.
Usage
The term "tire iron" refers to the tool itself. It is a compound noun where "tire" specifies the tool's purpose, and "iron" refers to the metal from which it is traditionally made. It is used as a countable noun.
Examples
- "I had a flat tire, but I couldn't change it because I forgot the tire iron in my garage."
- "Using a tire iron requires some force and care to avoid damaging the wheel rim."
- "The mechanic grabbed a tire iron from his toolbox to fix the puncture."
Advanced Usage
- The term is often used in the context of vehicle maintenance, roadside emergencies, and automotive repair.
- In some regions or contexts, a single, long tire iron might be referred to simply as an "iron," with the task understood from the situation (e.g., "Hand me the iron").
