What type of measurement is used to denote tire tread depth?

Tire tread depth is commonly measured in 32nds of an inch, which provides a precise indication of how much tread is available on a tire. This measurement system helps in assessing tire wear and determining when tires need to be replaced for safety reasons.

Using 32nds of an inch offers an easy reference for consumers and professionals alike, allowing for quick visual assessments and comparisons. For example, a tire with 8/32" of tread is generally considered to have good traction, while a measurement of 2/32" indicates it is legally worn out in many states. This unit of measure aligns with conventional practices in the automotive industry, emphasizing its relevance and practical application when evaluating tire condition.
