Durometer & Tread Depth Gauge

The Durometer & Tread Depth Gauge from LONGACRE is an essential diagnostic tool for mechanics, fleet managers, and automotive enthusiasts who need to assess tire condition quickly and accurately in the field or shop. This dual-function instrument eliminates guesswork when evaluating rubber durometer hardness and remaining tread depth, two critical factors that directly impact vehicle safety and tire longevity.

Engineered by LONGACRE, a trusted name in automotive precision instruments, this gauge combines two independent measurement systems in a compact, portable design. The tread depth function uses a probe mechanism that reads directly in 32nds of an inch, allowing you to verify whether tires meet the legal 2/32-inch minimum threshold or have reached the recommended 4/32-inch replacement point for wet-weather safety. The durometer scale measures rubber hardness on the Shore A scale, helping identify compound degradation and heat cycling effects.

This tool benefits anyone who performs tire maintenance, from independent shops to automotive enthusiasts. Its rugged construction and straightforward dial readout require no batteries or digital calibration, making it reliable in any environment. Whether you're diagnosing premature wear patterns or conducting pre-purchase vehicle inspections, this gauge delivers the precision data required for informed maintenance decisions.
