The tires on my car seem to __ very quickly. I need to change them again!

• A. wear out
• B. wear down
• C. wear off
• D. wear in

Answer: (A)

This is about choosing the right phrasal verb to express total deterioration from use. The best fit says the tires seem to wear out very quickly, meaning they become unusable due to wear and thus need replacement soon. Wear out conveys ending life from use, which matches needing to change tires again. Wear down would focus more on something getting thinner or shorter without necessarily reaching the point of being unusable. Wear off refers to a surface layer disappearing, not tires. Wear in is about getting used to something or breaking in, not tires. So the natural, precise choice is wear out.
