Question

question 21(multiple choice worth 3 points) (lesson 8.3 lc) you can use a ______ to test tread wear on your tires. ○ penny ○ air hose ○ car jack ○ lug wrench

Explanation:

To test tire tread wear, a penny is commonly used. The method involves placing a penny (with Lincoln's head facing down) into the tire tread; if the top of Lincoln's head is visible, the tread is too worn. An air hose is for inflating tires, a car jack lifts the vehicle, and a lug wrench removes lug nuts—none are for testing tread wear.

Answer:

A. penny
