Which tool measures tire tread depth and depth cut of a tire (32nd of an inch)?

• A. Depth Gauge
• B. Long Nose Pliers
• C. Duck Bills
• D. Locking Pliers

Answer: (A)

Measuring tire tread depth uses a tool that can read small depths with a scale in 32nds of an inch. A depth gauge is designed specifically for this purpose: you insert the probe into the tire groove until the base rests on the tread, then read the depth from the scale. This gives an exact measurement of how deep the grooves are, which is important for assessing wear and safety, including how much of a cut or wear remains. The other tools are hand tools meant for gripping or holding parts, not for measuring depth. Long nose pliers and duck bills are used to grab or bend, and locking pliers clamp onto objects; none provide a reliable or calibrated depth reading for tire grooves.
