What tool can help assess tire tread depth?

A tread depth gauge is a specialized tool designed specifically to measure the depth of tire tread accurately. This gauge provides precise readings, which are critical for ensuring that tires meet safety standards. Adequate tread depth is essential for maintaining traction, especially in adverse weather conditions, and can directly impact braking distances and overall vehicle control.

Using a tread depth gauge allows drivers to determine whether their tires have sufficient tread for safe operation. The deeper the tread, the better the tire will perform in rain, snow, and other variable driving conditions, reducing the risk of hydroplaning and improving overall handling.

While other options like a ruler or visual inspection can provide some insights, they lack the precision and reliability of a tread depth gauge. A ruler may not deliver exact measurements suited for tire tread, and a visual inspection can lead to subjective interpretations that could overlook safety concerns. Hence, employing a tread depth gauge is the most effective method for assessing tire tread depth accurately.
