Question

To be legal, a tire's tread must be at least __ inch deep. You can use a ___ to check the depth of your tire tread?

1) 1/16, tread depth gauge
2) 1/8, ruler
3) 1/4, penny
4) 1/2, coin

Answer 1

The legal minimum tire tread depth is 1/16 of an inch, which can be measured using a tread depth gauge or a penny for a quick check. Selecting the right measuring tool, like a ruler or measuring tape, is essential for accuracy in different measurement scenarios.

Step-by-step explanation:

To ensure road safety and legal compliance, a tire's tread depth must be checked regularly. Legally, the minimum tread depth is typically 1/16 of an inch. To accurately measure this, one can use a specialized tool called a tread depth gauge. However, for a quick check, a common household item such as a penny can be used. Insert the penny into the tread with Lincoln's head facing down; if the top of his head is visible, the tread is too shallow.

Measurement tools and their accuracy vary based on what needs measuring. For small objects or distances up to one foot, a ruler is appropriate, with most rulers showing inch markings. For longer distances, a yardstick or measuring tape might be the better choice. The importance of choosing the right measurement tool is crucial for precision.
